Objective:
To provide a cost-effective racing series for Lotus 7 and Caterham 7 cars modified to period standards (1972 or earlier SCCA). All cars must maintain the visual appearance of this era.

Mechanical Preparation:
Lotus 7 cars must use engines supplied by Lotus in production 7 cars.  The engine must be appropriate to the car's year of manufacture.  Lotus TC engines are allowed only in original Lotus Series III and IV cars.  Caterham 7 cars must use 1,600cc, cross flow Formula Ford specification engines. Caterham 7 cars with BDA engines there were registered in the 1999 season will be allowed to continue to compete until they are sold.  At that time they will lose their eligibility.

Engine modifications allowed:
1,600cc crossflow engines can be prepared to Formula Ford regulations with the exception that dual 40mm Weber carburetors and sump lubrication are allowed.  1558cc TC, 1498cc non-crossflow, 1340cc, 997cc and 948cc engines can be prepared to 1972 SCCA GCR with the exception that dual Weber carburetors, dry sump lubrication and roller rockers are allowed. 

Electronic ignition systems are permitted with or without distributor points.  Crank triggered ignition systems are not allowed.  Fuel pumps, exhaust systems, oil systems and alternators are open to OEM parts. 

Transmissions can either be 4 or 5 speed and must be comparable to the gearboxes supplied by Lotus and production 7 cars.  Differentials can be open or limited slip but not locked.  Rear suspension can be live axel or DeDion but must be of Lotus or Caterham production.  Gear ratios are open.  Brakes are open but no cockpit adjustments are permitted.  Suspension and chassis are open to OEM parts. 

Wheels and tires:
Wheels must be 13” diameter and no more than 6” width.  Tires must be treaded and of 60 series or taller.  Yokohama A008RS tires (185/60-13 or 205/60-13) are the spec tire for the series.  Treaded, bias-ply, vintage tires of 60 series or taller will be considered equivalent to the Yokohama spec tire. 

Safety Equipment:
Cars must be presented in a neat, safe and finished condition and must meet all Corinthian Vintage Auto Racing (CVAR) safety requirements.

Eligibility:
All eligibility issues and car preparation points will be determined by the Super 7 Challenge tech committee.  
Rules of the road:
The Super 7 Challenge series believes in the philosophy and spirit of vintage racing.  Furthermore, our events are typically part of Corinthian Vintage Auto Racing weekends.  Accordingly, our expectations of driver behavior mirror those of CVAR.  We believe that sportsmanship and racing enjoyment go hand in hand.  This does not mean our races are parades of cars with no passing.  Our goal is to enjoy close, competitive racing while maintaining a margin of safety.  We hold this same goal for all participants, regardless of financial resources, car preparation or driving ability. 

Driver Etiquette:
Your driving is expected to be the highest standard for the protection of everyone involved.  Drivers will be observed and judged for safe driving by the events Race Chairman, Chief Steward, course officials and peers.  If any driver is driving in a careless, unsafe or erratic manner, they will receive a black flag.  They must immediately report to the hot pit area for a conference with Chief Steward or his designee(s).  If given a second black flag, the driver will report to the hot pit for another conference with the Chief Steward and then return to the paddock for the remainder of the scheduled track season.  If given a third black flag, the driver will return to the paddock and be excused from remainder of the weekend.  If there is any car contact with another car or other object, the responsible driver will be excused for the remainder of the weekend.  They may also be subject to further review and possible additional penalties. 

Unacceptable driving behavior includes chopping, blocking and car to car contact.  Chopping occurs when an abrupt return to the racing line is made after passing another car.  Driver should provide a comfortable margin before moving in front of a car they have just passed.  Blocking is intentionally moving away from the normal driving line in order to prevent a passive maneuver by a pursuing car.  This is not acceptable.  Along that same line, passing maneuvers should never force another car off the racing surface.  When making a close pass, the overtaking car should decelerate enough to be in control enough to allow side by side racing through the next corner of necessary. 
 
In addition, the car in front has the right of way and need not yield to the car behind.  However, if the car ahead is clearly much slower than an overtaking car, as a matter of sportsmanship, the slower car should yield the right of way to the much faster car when it can be done safely.  The responsibility for the decision to pass another car and thus for the safety of the pass, lies with the overtaking car.  Pass must be completed without requiring the overtaken driver to take evasive action to avoid contact with the overtaking car.  This does not relieve the overtaken driver for any responsibility.  Both drivers must be alert (i.e., constantly checking frontal field of vision and mirrors) and be observant to what is occurring around them at all times.  It is the responsibility of the overtaken driver to maintain a consistent and predictable line of course of travel so that an overtaking driver will not find himself committed to the passing line only to have the overtaken car suddenly swerved into that line, resulting in unavoidable card contact.
