3 SPECIFIC TECHNICAL RESTRICTIONS AND GUIDELINES. The Technical Regulations for the Audi R8 LMS Cup are very specific with regard to the car adjustments that are authorised (see Regulation C3.2). This document serves to provide specific parameters for a number of the adjustments. This Technical Restrictions/Guidelines document may be updated by the Series Manager at anytime (including during an Event). Once issued (by Bulletin) the new version of the document becomes the only version which is valid and supersedes all past versions entirely. The most up to date version of this Cup Car Technical Restrictions/Guidelines document will be listed in the Event Bulletin. If any part of the text of this Cup Car Technical Restrictions/Guidelines document conflicts or contradicts that within the Regulations then the text within the Regulations shall take precedent. GENERAL ADJUSTMENTS INFORMATION. The following set-up adjustments are authorised and may be made at any time. a. Tyre pressure, within the range included in section TR1 of this Technical Restrictions/Guidelines. Further details are included within TR1 and Regulation C14.8. b. Adjustment of front and rear shock absorbers for bump and rebound, within the designed limits of the original equipment. Further details are included in TR2 and Regulation C6.1. c. Roll bar position, using the existing adjustment holes of the original equipment. Further details are included in TR3 and Regulation C6.3. d. Rear wing position, using the existing adjustment holes in the 2015 wing mounting. Further details are included in TR4 and Regulation C9.1. e. Adjustment of the ASR (Acceleration Slip Regulation traction control) using the cockpit mounted adjusting dial. Further details are included in TR5. f. Adjustment of the ABS (Anti-Blocking System) using the cockpit mounted adjusting dial. Further details are included in TR6. g. Steering column adjustment, within the designed range of the original equipment. Further details are included in TR7. h. Seat, individual adjustments may be made by adding or removing seat cushion padding. Further details are included in TR8 and Regulation C7.3. i. Brake bias, within the range of the 2015 upgrade included in section TR9 of this Technical Restrictions/Guidelines. Further details are included in TR9 and Regulation C13.2. j.

TYRE PRESSURE REGULATION C3.2a & C14.8. Tyre pressure adjustments may be made at anytime (remembering relevant Regulations such as Red Flag etc). The minimum cold tyre pressure must be 1.4 bar for the front Slick tyres and 1.2 bar for the rear Slick tyres. Michelin s recommendation and instructions should be respected. Tyre pressure adjustments on the grid can only be performed by the Competitor Technical crew or representative of Michelin. Audi R8 LMS Cup Cup Car Tech. Restrictions: Published v1.0

4 Michelin Recommendations: Important note regarding the Customer Competition race car tires Michelin Group After a run, the delta of temperature between the inside shoulder and the outside shoulder has to be less than 20 C Exceeding of some of these data levels (e.g. camber) may cause tyre damage or a drop in performance: higher tyre wear, influence concerning balance problems (oversteer/understeer), lap times will finally also drop (less constant). One stint is equivalent to the mileage indicated (including a maximum of 2 pit stops and/or driving under pace car). At this mileage and this speed limit, the integrity of the construction is guaranteed for endurance but not for wear or grip potential. Therefore, depending on the conditions of use, a tyre: Could be worn before achieving the indicated mileage, Could be only partially worn even though the indicated mileage has been achieved. In this case, the integrity of the construction cannot be guaranteed, the tyre must be replaced. These recommendations are valid unless the tyre has been damaged for example puncture or flat spots. The recommendations regarding rain tyres are only for wet conditions and not intended for a drying track. For any use apart from the defined recommendations, please contact Circuit Michelin technical department phone: +33 (0) & +33 (0) Please also see the Michelin technical data sheets for these tyres.

16 TR16. TIMING TRANSPONDER REGULATION C15.4. The timing transponder supplied by the Organiser must be fitted within the inner wheel arch using the existing thread location exactly as per figure 14 below. The figure shows placement on the left but the timekeepers may stipulate either the right or the left as dictated by the circuit configuration. Figure 14: Timing Transponder location. This can be either right or left depending on the circuit. TR17. LAUNCH CONTROL - REGULATION A Audi Sport customer racing has developed a launch control (LC) system that must be used at the start of any Standing Start race in accordance with Regulation A The LC limits the wheel slip to deliver consistent starts that maximise the acceleration off the line. The LC has 7 settings which are controlled by the position of the ASR switch. Only positions 1, 2 and 3 are permitted within the Audi R8 LMS Cup. This can be checked with the use of data after a race. The LC controls the engine speed prior to the start and then regulates slip up to 80km/h. The regulation is deactivated at 80 km/h, or when the throttle is lifted, or when 2 nd gear is selected. TR17.1 USING LAUNCH CONTROL. To enable the LC the following steps are taken: 1. Push Pit Limiter (cruise control) lever up for 0.5 sec. 2. Depress throttle and clutch simultaneously. 3. Lift clutch fully to start keeping the throttle at maximum. To cancel the LC at any time you can: 1. Lift off the throttle. 2. Shift up to 2 nd gear. 3. Push the Pit Limiter (cruise control) lever down. Figure 21 shows the LC request and LC active displays on the dash. Audi R8 LMS Cup Cup Car Tech. Restrictions: Published v1.0
