3 MEMBERSHIP Membership in Monoposto Racing is open to any person from any country who wishes to be connected with vintage and historic singleseater racing and registers his or her car(s) with Monoposto Racing. As a registered member you may score points in Monoposto-sanctioned events, participate in the various class championships and enjoy the trackside socials and camaraderie. PHILOSOPHY OF MONOPOSTO RACING The philosophy of Monoposto Racing is fairly simple and involves a few basics. 1. Single-seater car owners are expected to participate in Monoposto Racing to enjoy the fellowship and competition with their Monoposto Racing peers. 2. The cars competing in Monoposto events will be restored to the authentic, original condition as defined by the following rules and presented at each event in pristine condition. 3. Specific safety upgrades, such as dual braking systems and onboard fire systems are recommended and strongly endorsed; however, performance upgrades such as oversize engines, bigger tires, etc. are specifically forbidden. Please read the rules carefully and abide by them. We do not want the embarrassment of having to deal with any Monoposto member with an illegal vehicle. Also remember when reading the rules to assume that if it is not specifically spelled out in the rules, it is not allowed. If you have any questions, please contact the representative for your particular vehicle class. PURPOSE OF MONOPOSTO RACING The purpose of Monoposto Racing is to: 1. Preserve, restore and campaign vintage single seat, open wheel racing cars. 2. Create an amateur racing format for sportsmen that equally emphasize participation and competition. 3. Establish and maintain rules and regulations that hold cars to a high standard of authenticity and preparation while requiring or encouraging current safety upgrades. Page 3 of 66

4 4. Organize and promote North America s premier Vintage open wheel racing series for classes in the Formula Classic racing group and the F70 racing group. 5. Provide its membership with the opportunity to become part of a collective racing family. DRIVER QUALIFICATIONS AND LICENSING Most organizing clubs offer some type of licensing and all participating clubs are covered under a national license provided by the Vintage Motorsport Council [VMC]. In Canada and Europe, most licenses are provided by the national racing associations which are normally acceptable by the race organizers at Monoposto events. If you are registering for scoring as a new member, Monoposto Racing will review your racing experience prior to accepting your registration. Remember, that Monoposto Racing, through its Formula Ford class, has one of the best starting points for anyone wanting to race automobiles. It remains the largest, purpose-built racing class in North America after 30 years and continues to be the training ground for virtually all professional drivers on their way up the ladder. In short, it is a great place to start. RACE GROUPS Monoposto Racing has 9 distinctly different classes of cars ranging from Formula Vee to Formula 1 cars. They are essentially broken down into two groups, and at most racing events there will be a race for each of the two groups. Formula Classic Formula Classic is differentiated from Formula 70 by the fact that all the cars must run on treaded tires of specific sizes as noted in the rules. They cannot use any type of down-force in the form of wings or bodywork. Monoposto Classic runs from the late 1950s through to Within the following rules, we have attempted to list as many cars as we are aware of that fit into the specific rules for each class; however, if you come across a car that is not listed, please check with your Class Director to see if your car can be brought into Monoposto Racing. Their names and addresses may be found at Monoposto.com. Page 4 of 66

5 Formula 70 Formula 70 includes cars from the late 1960s to 1979 and FF70 cars produced through They run on slick tires and with wings creating down-force (with the exception of FF70 cars which do not have wings). Note: tunnel hulls and the like creating ground effects are not permitted. These cars are generally much faster than the Classics and can include period Formula I and Indy cars. For each type of car, we have a Class Director. They would be pleased to answer your questions or help you with interpreting the rules, so please feel free to contact them. Their names and addresses may be found at Monoposto.com AUTHENTICITY AND LEGALITY Part of the eligibility consideration is keeping cars legally within the rules. Many things are readily visible such as tire size, etc.; however, the most difficult area, which unfortunately recurs from time to time, is engine legality. Oversize engines are not permitted. The specifications for engine size, etc. are set out in the rules for each class. In addition, you are asked to get from your engine builder a certification letter which indicates the engine in your car has been built to specifications for your particular class. In the case of Formula Ford for example, this goes beyond not only cubic capacity but also into the use of some of the specific engine components. If you have any questions in this area, please carefully review the rules with your engine builder and speak to your Class Director if you require additional help. On a random basis, checks for compliance with the rules will be made on selected cars. The authenticity and correctness of each vintage race car is the primary responsibility of the car entrant. If there are any questionable items related to the vehicle, it is the entrant s responsibility to have original documentation to validate the questionable areas. DRIVER ELIGIBILITY AND QUALIFICATIONS Race series participants must be registered members of Monoposto Racing and have completed the Monoposto Racing registration application for their car. Drivers should have a competition license from SCCA, CASC [Canada], VMC [Vintage Motorsport Council] or their respective race organizing club such as HSR, SVRA, etc. that is acceptable to the organizer of the race(s) he or she wishes to enter. In addition, for a driver to be scored he or she should have evidence of recently having attended a professional driving school and/or had Page 5 of 66

6 some wheel-to-wheel racing experience in comparable cars. Monoposto Racing will review your background and may have further discussions with you prior to granting you permission to be scored in our series. Driver health is very much a critical part of safety and enjoyment of Monoposto Racing. We tend to work hard upgrading our cars, but sometimes fail to maintain our own physical condition. It is vitally important that you have regular medicals and ideally maintain a physical conditioning program so as not to take chances with your life or the life of anyone else. Remember, all racing can be dangerous. Advertising MISCELLANEOUS Only commercial advertising carried on the particular car while racing during its competitive career will be permitted on bodywork and/or wings. We strongly encourage you to carry a Monoposto Racing decal as well as those decals of our series sponsors on your vehicle. Beyond that, advertising on vehicles is limited to the advertising which was carried on a particular car when it raced during its competitive career. Monoposto Race Coordinator There will be a designated Monoposto Race Coordinator at each event. The MRC will coordinate amongst the Monoposto drivers and the organizer and generally assure that any issues that may arise are resolved. Track Technical Inspections Technical Inspections will be performed by the race organizer. These Monoposto Racing Rules and Regulations will be observed. Starting Procedure At virtually all events, we have rolling starts with one pace lap prior to the start. CLASS CHAMPIONSHIP AWARDS Throughout the season, we maintain records of the finishing positions of our members in all Monoposto-sanctioned events on the following basis of scoring. Points accrual will not occur in a season until a member has registered his or her car(s). At the end of the season, the first place finisher in each class is awarded a trophy. Plaques will be presented to the 2 nd and 3 rd place winners as well. At the discretion of Page 6 of 66

7 Monoposto Racing trophies and plaques may not be presented for a particular class when that class has a very limited number of entries over the course of the season. An example would be when there are only one or two entries per race in only two or three races for the season. Championship points are awarded as follows. Points Scoring There will be two points races at each event: the qualifying race (typically on Saturday) and the final race (typically on Sunday.) Each will count toward the class championships. The organizer will grid the Saturday race based on lap times from sessions earlier in the weekend. The grid may be modified by the organizer for safety reasons. The starting grid for the Sunday race will be based on the fastest lap times in the Saturday race so if you are unable to run the full Saturday race, you may still have established a grid position for the Sunday race. If for some reason Saturday qualifying race cannot be held, championship points will not be scored and the race organizer may choose to use results from earlier in the event to set the grid for the Sunday race. In this case, Monoposto will follow the direction of the race organizer. Finishing Position Scoring.. 1st place finish in class - 16 points.. 2nd place finish in class - 14 points.. 3rd place finish in class - 12 points.. 4th place finish in class - 10 points.. 5th place finish in class - 9 points.. 6th place finish in class - 8 points.. 7th place finish in class - 7 points.. 8th place finish in class - 6 points.. 9th place and beyond - 5 points Notes 1. Cars which start a race and are unable to finish will be awarded 5 points. To be eligible for finishing position points, a competitor must complete a minimum of 50% of the total laps of the race. Page 7 of 66

8 2. For class championships, a participant must participate in a minimum of five race weekends. Points will be counted on the basis of the ten races (remember there will be two each weekend) in which the participant receives the highest points. The Class Champion will be the racer who has accumulated the most points. A Class Championship may be won by the same racer in consecutive years. 3. In the event of ties the class championships will be decided by a comparison of the results from the races in which the tied drivers competed against each other. In the event that this cannot resolve the tie there will be co-champions. 4. Scoring will be based on how you finished in your race. Unfortunately, not every competitor in an event will be a registered Monoposto Racing member; however, if you are the among racers registered with Monoposto Racing to finish you will be scored first even if a non-registered racer in your class finished ahead of you. 5. Anyone causing an incident serious enough to require disciplinary action, or otherwise engaging in behavior that threatens the safety of fellow competitors, officials or race attendees will void all championship points for that race. The President of Monoposto Racing in consultation with the Monoposto Race Coordinator will make this determination. 6. Series participants found to be running illegal cars or oversized engines will forfeit all points to date. Cars not in compliance with the rules will be suitably noted in the vehicle log book and Monoposto Racing will retain records to ensure the cars are brought into compliance at future races. SAFETY SAFETY RULES ARE ESTABLISHED BY THE RACE ORGANIZER BUT THE FOLLOWING ARE HIGHLY RECOMMENDED: All cars should: 1. Have SCCA-type roll bars at least 2 inches over driver's helmet; 2.

Any member requesting approval for competition of a car built between January 1, 1970 and December 31, 1972 must do so in writing to the Monoposto Racing FB Class Director. CLASS FB AND F2 TIRE RULES BACKGROUND INFORMATION In 1969 both the SCCA GCR, and the FIA Rules addressed wheels and tires on Formula B and Formula 2 cars as open no limitations or restrictions. As a practical matter the size of the tire was determined by market availability of suitable tires. In the U.S., Formula B cars ran almost exclusively on Firestones and Goodyears. Neither Goodyear nor Firestone manufactures tires today that would match 1969 tires. This essentially leaves Dunlop and Avon as suppliers. Page 16 of 66

17 The tread width aspect ratio is important for at least four reasons: (Tread width aspect ratio is the ratio of the section height to the tread width.) 1. To preserve the vintage look of the cars in our series. Low, wide tires look contemporary. 2. In 1969, the English and European designers tended to run tall tires on wide wheels with narrow treads in search of tread stability. 3. Modern tires tend to have more perpendicular sidewalls; the difference between the sidewall, or section width, and the tread width, is not as great. 4. Tread width is the major factor affecting relative performance in a racing tire. The section width aspect ratio used in the passenger car tire industry generally describes the width of the body of the tire, which is important when you are dealing with body work clearance and ride height. Tire height: the cars we are concerned with are pre-1970, or cars up to 1972, which are prepared to 1969 standards. If the suspension pickup points and geometry are original, most of them will require tires of 22" to 23" in order to maintain reasonable ride heights and roll centers. If a 1969 car works well with 19.5" front tires, it is likely the suspension has been seriously redesigned. Occasionally grooved Avons have appeared with a very aggressive tread pattern with fewer grooves around the circumference of the tire than anything seen in the late 60's. After much consideration the following tire specifications have been adopted: The tires listed should be the proper width to fit the wheels being used. Fitting too wide a tire will cause the tread surface to be concave, which will not be productive. Avon tires listed must be A-11 compound or harder. FB and F2 cars must have front tires with a minimum diameter of 21 inches and a minimum rear tire diameter of 22.6 inches, except for earlier cars with 8" and 9" rear wheel widths. FB cars with 8" and 9" wide rear rims may use rear tires with a 22" diameter. All racing tires, including FB and F2 tires, must have a minimum of 2/32" tread depth to start a race. Rain tires may be used for FB/F2. Avons must be grooved to the approved Avon Pattern, and the Dunlop radials with the S2W construction, must be grooved to the approved Dunlop rain pattern.

19 APPROVED FB/F2 TIRES Avon Bias Ply Minimum Number of Groves with FB Size Pattern 7.0/ / / / / / / Dunlop Radial Minimum Number of Groves with FB Size Pattern 190/535R /570R13 6 Dunlop Bias Ply Approved Size Pattern 175/ CR / CR / CR / CR / CR 65 Tires not on this list may be accepted upon approval of the Monoposto Board. Tread patterns must be supplied by the manufacturer and suitable for all-weather use. The MR Board may disapprove new tread patterns if they do not meet the spirit of historic rules. Recapped tires may not be used. Avon bias ply and Dunlop radial tires are manufactured as slicks and must be hand-cut to the approved Monoposto FB pattern with the minimum number of circumferential grooves as specified above. Alternatively, they may be cut with more grooves to match the Page 19 of 66

20 traditional historic Avon all-weather pattern, which is similar to the Dunlop CR82 pattern. The Dunlop Formula Ford tire uses the CR82 pattern. Additional grooving is not allowed. Page 20 of 66
