1999 FORMULA VEE REGULATIONS (PRE-1970)

These rules describe and specify Formula Vee racing cars as they raced in the 1969 racing season.  This is a vintage racing class; the cars shall be presented and raced substantially as they might have been in 1969.

Vintage Formula Vee is a class for single seat racing cars based on components from the standard Volkswagen 120 series Type 1, U.S. model sedan (imported by VW), as originally manufactured and imported from 1961 to 1965.  Since it is a restricted class, all allowable modifications are stated herein.

Any Formula Vee manufactured prior to January 1, 1970, is eligible for Monoposto Racing Formula Vee provided it complies with the following rules.

No component of the engine, power train, front suspension, or brakes shall be altered, modified, or changed, nor be of other than VW manufacture, unless specifically authorized herein.

The bodywork is the original bodywork, or is substantially identical to the bodywork installed when the car was originally manufactured.

The car must originally have been manufactured without a camber compensating device; or with a cable or strap compensating device, a camber compensating spring, or a Z-bar.   Any of these devices may be installed if the car meets thhis "originally manufactured" test.  Zero roll rear suspensions are not permitted.   Exception: The Shadowfax as built by Mr. Harvey Templeton in 1969.

Minimum weight, without fuel or driver is 825 pounds, wheelbase is minimum 81.5"; maximum 83.5" and track is front 51.4"; rear 50.7" (standard VW sedan).  A small tolerance is allowed for cars using the permitted 4.5" rims.   Overall length is minimum 123" and maximum 127" with the body depth at firewall: min. 25" and maximum 34".

The engine shall be a standard VW 1200 powerplant, based on part numbers 111-100-021 and 113-100-025, and of 1192 cubic centimeter displacement.  Any part listed by manufacturer as a current, superseding part for the standard VW 1200 series, Type 1, U.S. model sedan and interchangeable with the original parts may be used.

Engine components shall be assembled in standard configration.  Exceeding the wear limits specified in the VW manual or in other official VW guides is not prohibited provided that the specifications, tolerances, and dimensions specified in these rules are not exceeded.

Balancing of all moving parts of the engine is allowed provided such balancing does not remove more material than is necessary to achieve the balance except on those compponent parts where minimum weights are herein specified.

a. 1192 cc engine dimensions:
