1998 SVRA Supplemental Regulations and Class List
Competition Group Three
(updated 3/7/98)
1. Eligibility: Recognized series produced sports cars and sedans in
production prior to 1968. Other cars by invitation.
2. Background and philosophy: Group Three consists mainly of medium
displacement sportscars that represent the ‘Golden Age’ of club racing in the
USA. These cars were the main stay of the SCCA production car classes. Cars
are expected to be prepared to the SCCA standards that were in effect at the
end of the eligibility period (1967). Similar models prepared to the FIA or
other regulations are included, but may be reclassified accordingly. Group
Three classes generally follow the SCCA classes of 1967, with some adjustments
for cars that were either not recognized by the SCCA or have specifications
that significantly change their relative performance.
3. Modifications: As listed in the SVRA General Rules and Regulations, the
SVRA Supplemental Rules for the make and model, and any period rules that are
appropriate. Cars marked with [ * ] have preparation guidelines published by
SVRA to help define the period standards. All competitors are expected to
obtain and understand these regulations.
4. Approved tires: Avon: 5.0/22-13 & 6.5/23-13 (7290 compound only)
