6 Part 1 General technical rules 1. Accepted cars Only vehicles of the model Porsche 911 GT3 Cup, type 991 Gen I and Gen II (a special series produced by Porsche AG), of the model years and which fully comply with these Regulations are eligible to participate. The vehicles must meet the technical specifications of these Regulations and Appendix J of the International Sporting Code in full. A change of vehicles has to be applied for in writing by the team (entrant) and must be approved in written form by the Series Organiser prior to the change. The decision to approve a change of vehicle is at the absolute discretion of the Series Organiser. Porsche 911 GT3 Cup Cars of model year with a chassis of a Gen II ( ) are also allowed. (Attachment 18) This Porsche Cup cars are considered as Gen I (MY ) cars and must comply with the general Technical Regulations and the Technical Regulations specific for the Porsche 911 GT3 Cup, type 991 Gen I (MY ). 2. Principles of the Technical Regulations in accordance with Art of Appendix J (FIA ISC) These Technical Regulations Technical manuals of the eligible vehicles Technical information of Porsche AG Spare parts catalogues of the eligible vehicles General provisions, definitions and clarifications regarding the technical rules Wiring diagrams of the eligible vehicles 3. General/preamble Everything that is not expressly permitted in these Regulations is prohibited. Permitted modifications must not result in any illegal modifications or infringements of the Regulations. Any permitted changes may only serve the intended purpose. The decision of the Series Organiser shall be final regarding any interpretation of these Regulations. The Series Organiser reserves the right to amend and extend these rules Work may be carried out within the normal scope of vehicle maintenance or for the purpose of replacing parts damaged as a result of wear or accidents. Modifications and built-in components are only allowed within the scope defined further in these Technical Regulations. Parts damaged as a result of wear or accidents may only be replaced by genuine Porsche parts which are dedicated to the eligible vehicles. The use of components manufactured by Porsche AG for other groups of vehicles (e.g. Porsche road vehicles) is prohibited. Standard fastening components on the complete vehicle, such as nuts, bolts, washers, spring rings, spring washers, split pins, may only be replaced by genuine Porsche parts. In the case of threads, the thread type, size and pitch are to be retained. Only Porsche genuine spare parts must be used. This means it is not allowed to use identical parts from the same manufacture without the Porsche parts number indication. If the entrant has doubts regarding any parts to be original, the entrant must check this with the Technical Manager, but it is the responsibility of the entrant to only use original Porsche parts. Parts and bodyshell must not be modified. In case of damage the car must be repaired to its original state. The tools and/or measuring equipment used by the Technical Scrutineers during scrutineering is binding and any appeal or prosecution against the tools/measurement equipment in any way, is not allowed. As described further in these regulations the entrant has the possibility to use the tools/measurement equipment of the organisation, to check his car if it is complying with these Technical Regulation. This way the entrant has the possibility to compare the measuring result, taken with the entrant s measuring equipment, with the results taken with the measuring equipment of the organisation, and adjust the Porsche Cup car accordingly these Technical Regulations. The scales (used to weigh the Porsche Cup cars, drivers, fuel or parts) are included in the kit with tools and measuring equipment used by the scrutineer. Which means, any appeal or prosecution against the scales used by the scrutineer, is not allowed. At the start of the pre event Technical Scrutineering, which means the Technical Scrutineering before the Free Practice session(s), the Technical Scrutineers and/or Series Organiser indicates to the entrant where the ground APPROVED BY KNAF UNDER PERMITNR

7 clearance and vehicle weight will be measured. This can be done by mentioning it in the Supplementary regulation, by bulletin, any other team info or verbal. The ground clearance is measured on a surface indicated by the Technical Scrutineers and/or Series Organiser. This surface can be; a measuring plate, a surface exclusively designated for this purpose or any other surface. This surface is the reference surface and this surface is binding. Any appeal or prosecution against the reference surface in any way, is not allowed. The entrant who engage/signs up for the Porsche GT3 Cup Challenge Benelux championship accepts and acknowledges these Technical Regulations. In any case it is the responsibility of the entrant to be in accordance with these Technical Regulations. 4. Exclusion of a Porsche GT3 Cup car, type 991 The PGT3CCB has the right to exclude a car from competing during an event when the car isn t repaired correctly after an incident. It doesn t matter if this incident took place during a Porsche GT3 Cup Challenge Benelux event, unofficial test drive session or other championship events. The arguments could be: Safety, in the broadest sense of the word. Car is in violation with the Technical Regulations of the Porsche GT3 Cup Challenge Benelux. Any reason that Porsche AG (in the broadest sense of the word) defines by any medium (verbally, phone call, , letter,...) Damaged roll cage Repaired roll cage without Semcon certificate. Damage on the front of the 991 cup car. (Reference: Technical Manual Porsche 911 GT3 Cup type 991) If the carrier is damaged behind the cutoff line (2), it is not possible to carry out the repair work. =>The damaged chassis must be replaced by a new one. Damage on the rear of the 991 cup car. The use of aluminium components influences enormously repairs with respect to the realignment of deformed or bent components. This is due to the significantly lower yield strength and fracture elongation. As a consequence, cracks, dents or creases form faster, which in turn limits the reparability significantly. Even if there are no visible signs, damage in the material can still exist. In the event of just a limited local repair (reforming original contour) the material loses its original strength and therefore no longer possesses the original mechanical properties. Subject to the point of application and demands made of the material in this area, it is possible to reform aluminium sheet to a limited extent. In this case, damage the structure is only apparent when a jig is fitted or by measuring check points on the chassis. Cast aluminium parts that show a deviation of +/- 2 mm are out of tolerance. The chassis must be replaced by a new one. APPROVED BY KNAF UNDER PERMITNR

8 Damage Diagnosis: must be replaced. If casting deviations of greater than reference: 0 mm + / -2 mm are found, the chassis A crack and deformation of more than 2mm in the body is visible in the picture underneath. In the CAD image it is clearly visible that this area is cast aluminium. ->Cast aluminium parts that show a deviation of +/- 2 mm are out of tolerance. The damaged chassis must be replaced by a new one. APPROVED BY KNAF UNDER PERMITNR

9 5. Parc Fermé After the qualifying sessions and de race sessions all cars need to go immediately after the session to Parc Fermé. Parc Fermé is closed, this will be indicated with a red flag. Parc Fermé is open, this will be indicated with a green flag. Both flags will be shown on an easy to see spot, at the Parc Fermé location, at the PGT3CCB spare parts truck, at the PGT3CCB tent or elsewhere. This will be communicated in the Supplementary regulation, bulletin, any other team info or verbal. At least one team member must be present at the outside borders of the Park Fermé, during the whole Park Fermé period. 6. Pre-Event Scrutineering Before the start of each event a pre event scrutineering time table will be made up. It is the teams (entrant) responsibility to attend the scrutineering in time, at least 5 minutes in advance. If the competitor can t attend in time, the Technical Scrutineers must be informed before the start of the pre event scrutineering session. If this isn t the case a penalty will be decided by the Stewards. Per car only 2 mechanics, 1 team manager and the driver of the car are allowed in the scrutineering area. All persons whose car isn t scrutineered at the moment, aren t allowed in the scrutineering area. The Porsche GT3 Cup car will be checked on safety, documentation, additional ballast sealing, car layout, general conformity, camera system If the competitor has the authorisation to leave the scrutineering area, the competitor has the possibility to weigh the car and measure the ground clearance with the official equipment of the organiser. The competitors need to present the Porsche 991 GT3 Cup cars in perfect condition. The team must take with them to the pre event scrutineering: Porsche 991 GT3 Cup car (stickers + camera system + ballast, ) Documentation of the vehicle: -Data sheet -Safety cage certificate -Fuel tank certificate -Drivers racing equipment: -Overall -Underwear -Balaclava -Socks & shoes -Gloves -Helmet -FHR-system ( e.g. HANS) Additional equipment: -Bottle of compressed air -Air jack -Safety system to put under the car -Nut gun / torque wrench -Wrench socket centre lock 7.

13 9. Weights It is the entrants responsibility to ensure that at all times during the event the mandatory minimum weights described underneath are reached. The minimum weight must also be observed when the levels of operating liquids are under minimum level. The Technical Scrutineers shall specify a weigh scale for the checking of weight of the vehicles and drivers. This could be two different scales, one system to weigh the car, one scale to weigh the driver. It is referred to here as the official scale. The official scale is located in the Series Technical Scrutineering tent or in an alternative designated place. This is also the weighing area. This will be announces via the Supplementary regulation, bulletin, any other team info or verbal. The installation of ballast is permitted. Only original Porsche ballast components must be used to add weight to the vehicle to reach the minimum vehicle weight and to reach the minimum driver weight. These must be installed in the provided holders at the position of the passenger s seat in accordance with the illustration in Attachment 1. The ballast weights are identified by spare part numbers (Pn: / / ). The mounting of the ballast cover (Pn: B) is mandatory if the ballast base plate (Pn: A) is mounted. The ballast system must be mounted as described in the Technical manual or Spare parts catalog of the corresponding vehicle Minimum combined weight of vehicle + driver At no time during an event is the combined weight of a vehicle + driver allowed to be less than the mandatory minimum combined weight The mandatory minimum combined weight of vehicle + driver consists of: Weight of the vehicle with empty fuel tank Weight of the vehicle equalisation ballast excluding the weight of the driver equalisation ballast Weight of the inboard camera Weight of the driver Weight of the personal equipment of the driver as it is in the vehicle at the time when the weighing is ordered Weight of the driver equalisation ballast excluding the weight of the vehicle equalisation ballast The mandatory minimum combined weight of vehicle + driver per vehicle model year (GenI/GenII): Porsche GT3 Cup 991 Gen I (MY ): 1315kg Porsche GT3 Cup 991 Gen II (MY ): Will be determined, and announced by bulletin at the first event of the season Minimum vehicle weight At no time during an event is the weight of a vehicle allowed to be less than the mandatory minimum weight The minimum weight of a vehicle consists of: Weight of the vehicle with empty fuel tank Weight of the vehicle equalisation ballast, excluding driver equalisation weight Weight of the inboard camera The mandatory minimum weight of a vehicle per vehicle model year (Gen I/Gen II): Porsche GT3 Cup 991 Gen I (MY ): 1225kg Porsche GT3 Cup 991 Gen II (MY ): Will be determined, and announced by bulletin at the first event of the season Minimum driver weight At no time during an event is the weight of a driver allowed to be less than the mandatory minimum weight Minimum driver weight consists of: Weight of the driver Weight of the personal equipment of the driver as it is in the vehicle at the time when the weighing is ordered Weight the driver equalisation weight, excluding the weight of the vehicle equalisation ballast The mandatory minimum weight of a driver: 90kg It is the driver s responsibility to ensure that the sum of the installed equalisation weight plus his/her actual weight (including the parts of his/her personal equipment in the vehicle at the time of the order to weigh the vehicle) is reached at all times. APPROVED BY KNAF UNDER PERMITNR

14 9.4. Determining the combined weight of the vehicle and driver The Technical Scrutineers may in their absolute discretion decide to weigh the vehicle and driver separately or in combination. If the vehicle and the driver (together with all driver equipment) are weighed in combination, the weight plus 2.0 kg of weighing tolerance shall be added and the result shall be referenced against the mandatory minimum combined weight, which must be reached. If the vehicle and the driver (together with all driver equipment) are weighed separately on the official scale, the two weights plus 2.0 kg of weighing tolerance for the car and 0.5 kg of weighing tolerance for the driver weight shall be added and the result shall be referenced against the mandatory minimum combined weight, which must be reached. Prior to weighing a vehicle, the Technical Scrutineers will give the order to a team member to remove the remaining fuel from the fuel tank Weight changes during qualifying and race During the qualifying and race, the weight of the vehicle is only allowed to be altered by: Changing from slick tyres to wet tyres or vice versa. Consumption of consumable materials and fluids. Damage on the Cup car due to a crash or accident. On the way from the circuit to the Parc Fermé and in the Parc Fermé itself, and on the way to the postqualifying or race Technical Scrutineering, under no circumstances is weight allowed to be added to the vehicle or the driver Verification of the minimum weights by the participants on the official scale Entrants have the opportunity to check the weight of their vehicles and drivers during the event on the official scale with the permission of the Technical Scrutineers. Only the measurements recorded by the Technical Scrutineers shall be deemed accurate for the purposes of compliance with the regulations Personal protective driver equipment during weighing During the weigh-in, each driver must wear his/her complete driver apparel, plus the mandatory Frontal Head Restraint system Weighing of vehicles The vehicles are weighed as follows: Weighing of vehicles is carried out on the official scale. If a driver is given the signal that his/her vehicle has been selected for weighing, he/she must take the shortest route possible to the weighing area and turn off the engine. During weighing the driver is not allowed in any way to influence the weighing result. If a vehicle cannot reach the weighing area under its own power, it must be brought to the weighing area solely by marshals. If this is not possible, then the Technical Scrutineers can assign other persons for this purpose Leaving the weighing area Without the consent of the Technical Scrutineers, the driver is not permitted to leave the weighing area and the vehicle is not allowed to be removed Weighing after breakdown and vehicle remaining on circuit during qualifying and race If a vehicle breaks down during the qualifying session or the race and the driver leaves his/her vehicle, he/she must go directly to the weighing area to determine his/her weight. APPROVED BY KNAF UNDER PERMITNR

15 9.11. Determining the driver weights After qualifying and race, all drivers must go immediately on a direct route from the Parc Fermé to the weighing area to determine their weight. Drivers who are approached by the TV partner for an interview may interrupt their walk to the weighing area for the duration of the interview. Drivers who do not go directly to the weighing area to be weighed will be reported to the Stewards. The Stewards will take the final decision regarding a punishment. The drivers will be weighed individually. Any appeal against the observed weight must be immediately submitted to the Technical Scrutineers. During some events it can happen that the drivers will be weighed in the Parc Fermé, on a no official scale. Any difference between the official driver weight scale and the scale in Parc Fermé will be taken in account Replacement and loss of vehicle parts All vehicle parts that were replaced during the qualifying session and race must be presented to the Technical Scrutineers without request for inspection. The parts that were removed from the vehicle will be marked by the Technical Scrutineers if necessary and are not allowed to be modified in any way afterwards. These parts must remain in the pit or in the Technical Scrutineering tent in sight of the Technical Scrutineers or their assistants until released by the Technical Scrutineers. These parts can be considered when determining the weight instead of the replaced parts. In case of a loss of coolant, the final weight of the car may be only determined by draining all remaining coolant liquid (from engine, coolant reservoir, all radiators, all coolant hoses and connectors) and adding 22 kg to the measured weight of the car Parc Fermé rules for vehicle weighing Vehicles that have been specified for weighing are subject to Parc Fermé Regulations. It is forbidden to add or remove any substance to/from the vehicle after it has been selected to be weighed. The same applies during the weighing process and after the end of the race. Excluded are actions of the Technical Scrutineers Weighing in below the minimum weight If, during the post qualifying or post-race weighing procedure, the combination of vehicle and driver (including driver equipment) is found to be below the currently applicable minimum weight, the vehicle and driver (including driver equipment) will immediately be weighed together for a second and a third time on the same scales and in the same condition after the same session and with the same measuring method (car and driver together or separated). The maximum value of the 3 weights recorded is regarded as the actual weight of the combination of vehicle and driver (including driver equipment). Falling below the minimum weight will be reported to the Stewards and will be penalised Bringing the vehicle to the weighing area It is the entrant s responsibility to ensure that the race vehicle entered by him/her can be brought directly to the weighing area when instructed by the Stewards or the Technical Scrutineers at any time during the event. In any case, Parc Fermé rules apply to the vehicle from the moment of the order until the termination of the weighing process Regulations on the route to and in the weighing area Moreover, Parc Fermé rules apply to the route to the weighing area and in the weighing area itself. In this area, the only activities on the vehicle are those expressly permitted by the aforementioned persons. If a vehicle is not presented for weighing despite a request, the Technical Scrutineers will inform the Stewards Sealing the equalization weight The equalization weight mounded on the passenger side of the vehicle will be sealed by the Technical Scrutineers. Not a single vehicle can start with damaged seals. If the seals are damaged during a sessions the competitor needs to inform the Technical Scrutineers immediately. If a seal is damaged, at least one member of the Technical Scrutineers need to be informed immediately after discovering the damaged seal. If a seal need to be removed to do repair work, at least one member of the Technical Scrutineers need to APPROVED BY KNAF UNDER PERMITNR

16 be informed before removing the seal. The mounting of the ballast cover (Pn: B) is mandatory if the ballast base plate (Pn: A) is mounted. APPROVED BY KNAF UNDER PERMITNR

17 10. Ground clearance of vehicle The minimum ground clearance of the vehicle (with the driver in the vehicle), tyres at 2.0 bar ±0.1 bar air pressure must not be less than the specified dimension, as measured at the specified measuring points, at any time during the event. For the entire duration of the race event the ground clearance of the front axle is to be a minimum of 78,0 mm and the clearance at the rear axle a minimum of 100,0 mm. The measuring points at the front axle are the mounting bolts (M12x105) of the cross member/bodywork in relation to the reference surface and the machined rear surface in the direction of travel on the side section of the rear axle in relation to the reference surface. The ground clearance is allowed to be changed within the existing adjustment range Min ground clearance (All type 991, MY , MY ): Front: 78,0 mm Rear: 100,0mm Measuring point Attachment 5: Minimum ground clearance rear and front axle Porsche GT3 Cup, type 991 Gen II (MY ) Attachment 10: Minimum ground clearance rear and front axle Porsche GT3 Cup, type 991 Gen I (MY ) Measuring method The minimum ground clearance of the vehicle is checked on the measuring surface, using an appropriate height gauges or gauge block. The ground clearance of the vehicle is measured on a surface indicated by the Technical Scrutineers and/or Series Organiser at the start of the event. This can be done by mentioning it in the Supplementary regulation, by bulletin, any other team info or verbal. This surface can be; a measuring plate, a surface exclusively designated for this purpose or any other surface. The measurement is checked with the vehicle in the state that it ended its last session. This means with the same tyres that the driver ended its last driving session. Tyre can be inflated at 2.0 bar ±0.1 bar air pressure. The remaining fuel, left over from the last driving session, must stay in the car for the ground clearance measurement. The ground clearance measurement is done with the driver on board together with his full drivers equipment. If the measuring gauges can be accessed under the measuring points described above, the requirement to comply with the minimum height is satisfied. Any measuring tolerances will be taken into account by the Technical Scrutineers. The Technical Scrutineers may at any time in their absolute discretion check the ground clearance measurement with any set of tyres allocated to the respective start number used during the session that the check is performed during or after. The Technical Scrutineers may also use instruments such as measuring calliper or depth gauges to determine the vehicle height Measurement location The measurement is conducted on the measuring surface during Technical Scrutineering. The measuring surface is available to the participating teams to check the minimum ground clearance during this period after consultation with the Technical Scrutineers Failure to reach minimum height Failure to reach the minimum height will be reported to the Stewards and will be penalised.
