Corinthian Vintage Auto Racing (CVAR)
Race Car Classification Rules - 2007
CVAR accepts cars built to period regulations AND period practice for class. CVAR classification system based on 1972 SCCA classification. Cars not built to SCCA regulations will be reclassified by regulations committee.
Reasons for rules:
1. Cost containment: By allowing some cars to run with illegal equipment, we encourage others with proper cars to install expensive, illegal and often unreliable parts in order to have someone to race with. By freezing specifications at 1972, there can be no “trick parts” that crop up every year.
2. Rules standardization: By accepting standards that are in line with other VMC (Vintage Motorsports Council) groups, our members can run with other clubs across the country without having to re-engineer their cars. Also, members of other clubs will be encouraged to run Corinthian events.
3. VMC compliance: All VMC groups are working toward uniform tire and preparation standards. As a member of the VMC, CVAR will support those actions.
CVAR CHAMPIONSHIP
CVAR is proud to present our championship series. A winner will be crowned in each class, with a trophy . Trophy allotment based on number of cars entered in class during season. (up to next-to-last race of year). If less than 3 entries during season, 1st place trophy awarded. If 3 to 5 entries, then 1st place through 3rd place trophies will be awarded. If over 5 entries, 1st through 5th place trophies will be awarded. Points to be awarded for:
5 points -- for race entry
1 point - for starting each race on weekend (usually 1 on Sat and 2 on Sunday)
1 point -- for finishing each race (running at finish as determined by scoring)
10 points -- for correct period preparation as follows:
4 points -- for period-correct appearing wheels and tires (60 series or taller treaded tires on production cars). 50-series OK on CP cars.
3 points -- for correct body configuration (no spoilers, wheel flares, fiberglass panels, etc., if not allowed in 1972 GCR and PCS).
3 points -- for correct engine, transmission and suspension for period. Must conform to GCR(SCCA General Competition Rules), PCS (SCCA Production Car Specifications), FIA or IMSA regulations for car period. Alternate period regulations must be provided by driver.
Finishing position points: For last race on Sunday or designated feature race (one per weekend).
2 points -- for 1st through 4th place in class
1 point - for 5th and 6th place in class.
No minimum entrants required for points to be awarded. Overly aggressive/dangerous driving will be closely regulated and points may be deleted by the chief steward and/or race chairman. Irresponsible drivers may be excluded from championship or barred from CVAR events completely. Any driver found to be intentionally cheating will be disqualified from championship and subject to license suspension. For more point details see scoring info at bottom of regs.
Any car not believed to be in the spirit of vintage racing will be ineligible for championship.
Vehicle Regulations Committee decision is final. It is owner’s responsibility to justify questioned modifications by having copies of regulations, photos, etc. Points may be deducted for on-track infractions as determined by race officials. In case of tie at year end,driver with most wins during season is champion. If neither driver has any wins, second place finishes determine winner, etc.

NON-SCCA SPEC PRODUCTION CARS
Production cars built to 1972 or earlier alternate club regulations (RAC, FIA) are legal, but will be classified by the Regulation Committee by anticipated performance levels. Note that these regulations must be followed accurately - no picking and choosing from among several sets of regs. These cars can be re-classified at any time if they turn out to be too quick (cars built to SCCA regulations will not be re-classified). Entrant is responsible for documenting questioned modifications (must be of period practice and legality). Example: Lotus S-7 Twin Cam was not SCCA legal, but they were built by the factory and raced in England with the RAC. CVAR classifies them in C-Production.
SUMMARY OF ALL CVAR EXCEPTIONS TO 1972 SCCA PRODUCTION CAR REGULATIONS:
1. 302 allowed in any Ford product that took 260 or 289.
2. All Tigers run in BP, not CP.
3. All SCCA-approved production 911 Porsches run in CP.
4. Production cars may upgrade to bigger versions of their original carburetors or replace them with Webers with the same number of barrels (i.e. Midget with a single Weber in place of two SUs). Manifolds should be of period design. This regulation may be tightened down in the future.
5. The following cars can be built up from production versions (the SCCA required correct chassis numbers but we do not): GT-350, GT-500, Yenko Stinger, Abarth 124 Spyder, Porsche 914/6
6. Minis may use fiberglass noses in place of metal (but will be penalized 2 points).
7. CP XKE can substitute fiberglass hood in place of optional aluminum hood (with 2 points penalty).
8. 289 Cobra with Webers runs in AP as per 1965 SCCA regs.
9. CP 2.4 liter 911 was only homologated with factory mechanical butterfly injection and must be run as such. Other 911s can run Webers, factory injection or Solex carbs.
10. Wheel flares made from alternate materials will be penalized points.
11. CP TR-6, TR-5 or TR-6 powered TVR can substitute triple Webers for factory fuel injection.
13. Later models of production cars that were SCCA approved in 1972 may be backdated to 1972 specs, but they must be COMPLETELY backdated both technically and cosmetically.

CORINTHIAN CLASSICS: GROUP 4
Purpose: To encourage participation in vintage racing by cars that are of 1950s appearance and technology. They differ in spirit as well as equipment from our other CVAR classes since 1950’s production cars were not allowed as many modifications as they were in the 1960’s. They should, ideally, be suitable for road or racing and many performance modifications are discouraged or not allowed. Although 1961 is the nominal cutoff, some later cars are clearly ‘50’s technology while some 1960-era cars are not and will be excluded from this group. See attached list. Cars built prior to 1962 that are modified beyond these regulations may still be eligible for other CVAR groups. Although racing is not restricted, outright competition is not emphasized in this group as much as in other CVAR groups.
GROUP 4 PRODUCTION CAR REGULATIONS
1. Must have full interior with 2 seats, carpet (if originally installed) and door panels (not aluminum panels). Headliner may be removed for roll bar clearance. Seats, gauges, etc. may be substituted but not removed. Stock dash required but can be modified for instruments.
2. Wheels may be 1.5” wider than stock width as listed in the 1972 SCCA PCS or in manufacturers data. Cars with 16” standard wheels may substitute 15” wheels.
3. Wheels must be of period appearance (modern copies OK) or points will be deducted. No Revolutions or 3-piece wheels.
4. Tires must be treaded and of at least 60-series tall.
5. No body modifications allowed for tire clearance except rolling inside lip of fender. No light weight body panels unless homologated. Bumpers may be removed and windscreens used in place of windshields. No air dams or other aerodynamic devices allowed.
6. Gearbox must have original number of speeds and conform to 1972 or earlier SCCA PCS..
7. Brakes must of original type and size. Example: No disc brakes on 356 Porsche.
8. Carburetors must be of original manufacturer and number.
Internal engine/gearbox parts are restricted to 1972 SCCA GCR and PCS regulations.
9. Roll bars and all safety equipment required. Fuel cells recommended. No points penalty for any safety equipment including roll cages in closed cars. However, cages should not extend through firewalls or bulkheads to tie in to suspension points. No roll cages in open cars.
10. Cars may be lowered, springs substituted and sway bars added. Shocks may be replaced, but changing system (i.e. lever to tube) will result in loss of authenticity points or relocation to other classes.
11. Cars of approved model but not built in 1961 or earlier are allowed so long as they maintain 1961 appearance and mechanical configuration.
12. No replicas allowed (i.e. kit cars of modern manufacture).
13. No racing history is required for any car.
14. Cars outside the spirit of the regulations may be reassigned to other CVAR race groups by Authenticity Committee.
15. All body panels must be original material.
16. All trim, components and overall appearance should be visually similar to 1950s practice.
GROUP 4 MODIFIEDS
1. Must be in a period configuration and use period technology (1950’s) and parts.
2. Treaded tires required of 60-series or taller. 6” maximum wheel width. Wheels should be of period appearance (modern copies like Panasport, American Torque-Thrust, Halibrand, etc. OK).No 3-piece wheels allowed.
3. Brakes must be of period availability (no Willwood, vented rotors, etc.). Disc brakes may be substituted for drums only if fitted to at least one similar car prior to 1962. Proof is responsibility of driver. Any drum brake may be substituted for any other drum brake (including Alfin drums). Alternate period calipers may be used in place of Halibrand spot brakes.
4. The following cars are specifically NOT allowed in Group 4: Lotus 19, Elva Mk.6, Cooper Monaco. They run in BSR, Group 6 or CSR, Group 6 depending on engine.
5. Period sports-racers may be replicated using only period parts (including an original, non-repro production car frame). Owner must furnish documentation on car replicated. Example: Devin-Healery or Triumph, etc.

There will be representatives of the CVAR Authenticity Committee at tech to answer questions, or you can give us a call.
For period SCCA regulations, order the Historic GCR/PCS p/n 5684 ($35 SCCA members, $40 non-members) from the SCCA Merchandise Division. Or download PDF file of merchandise order form at: http://www.scca.org/interactive/index.html#merchandise
These regulations do not override any safety requirements mandated by CVAR. Fuel cells and roll bars/ belt assemblies are approved for all cars and do not detract from originality points. Roll cages in production and Group 4 cars should be contained in driver and trunk compartments.
Fuel cells required in all CVAR cars unless specifically exempted by head of tech due to exceptional authenticity issues. This is an insurance/liability issue.
CVAR CHAMPIONSHIP SCORING
1. All cars will be checked for authentic period preparation at the first event they run of the season. They will be classified and points will be assigned.
2. Cars that are prepared beyond allowable modifications will be penalized points, reassigned to another race group or excluded from competition at the discretion of the Vehicle Regulations committee.
3. Once the car has been scrutinized, it will not have to be checked the rest of the season. At subsequent events, it will be given the same number of points assigned. If illegal modifications are fixed, it is the drivers responsibility to notify Vehicle Regulations Committee so that correct points can be assigned. If a change is made that would make the car illegal, the officials must be notified so car can be penalized points or reassigned. Vehicle Regulations Committee will spot-check for continued compliance throughout the season. If a car is found to have changed to an illegal configuration without notifying the officials, it will be disqualified from championship and driver may be suspended from competition.
5. If a driver is reprimanded or disciplined for driving infractions, all championship points can be taken away by Chief Steward. Driver can also be disqualified from championship or have other disciplinary action taken. The penalty for overdriving is more than the reward for winning.
CVAR Points Deduction Table
These are the number of points that will be deducted from points total for the following illegal modifications:
Wheels/Tires (4 point max)
4 points for treaded tires shorter than 60 series on production/sedan cars.
Exceptions: CP cars can used 50-series tires without penalty. Cars in Group 2 with 15” wheels can run 50-series tires without penalty. This can change if suitable tires become available.
Tires shorter than 50 series in other production/sedan classes will result in reclassification to exhibition group. Vintage group cars must have 60-series or taller tires or they will be reclassified to other race groups. FF1 must run Monoposto-approved tire (see FF1 regs above)or will be moved to FF2..
No height requirement for other formula, sports-racer or slick classes. No hand-grooved tires allowed.
1 point for non-period appearance wheels
2 points for slicks on FV
Wheels wider than SCCA allowed will result in disqualification or reclassification.
2 points for substituting 16” rims for 15” in FIA class. Not allowed in any other classes.
In vintage and production classes, cars originally fitted with 16” wheels can use 15” wheels (XK-120, etc.) without penalty.
Body Configuration (3 points max)
1 point for wheel flares that were illegal in 1972 (alternate material, non-stock shape, excess size). OK for FIA.
1 point for removed door handles
2 points for non-legal hood/scoop configuration
3 points for dams/spoilers (must be removed by following season) if not legal in 1972 or earlier (1974 for FIA).
2 points for not having both seats/door panels/carpet in vintage class production cars (VA, VB, VC). Must be added.
1 point for not having original-type dash in production cars (may be modified)
Mechanical Configuration (3 points max)
Production cars with dry sump are moved up one class, but not penalized points so long as sump tank is not in driver compartment (not allowed). Dry sump on AP/BP production cars (but not A sedans) will result in reclassification to FIA class. CP cars with dry sump will be penalized 3 points but can stay in CP due to safety issues.
2 points for lever shock conversions.
Brakes may not be substituted on production cars. Must be period legal or car is moved to exhibition group.
No aftermarket electronic fuel injection on any car or will be moved to exhibition group.
Other illegal mechanical changes will be penalized according to severity of infraction.
Cars with more than 5 penalty points are not eligible for championship and may be moved to exhibition group.
