1998 SVRA Supplemental Regulations and Class List
Competition Group Five
(updated 1/26/98)
1. Eligibility:
a) Under 2.0 litre purpose built racing sports cars (sports
racers) as raced between 1960 and 1972.
b) World Sports Car Championship and World Manufacturer’s
Championship GT’s
and prototypes as raced between 1960 and 1972.
c) USRRC sports cars and Can-Am as raced before 1967.
d) Front engine "specials" as raced after 1959.
2. Background and philosophy: Group Five cars must be prepared as they were
during their competitive racing period. Since racing technology progressed
very rapidly during this period, there may be different specifications that
are period correct. It is SVRA’s intent to provide fair and equitable racing
amongst this diverse group of cars. Certain post 1970 cars may be considered
eligible and some pre-1970 cars with later specifications will not be
accepted.
3. Modifications: Since these cars mostly raced in open categories, there
will be variations within a particular make and model that are period correct.
Group Five cars are expected to have only period equipment and specifications.
It is the responsibility of a competitor to provide documentation for any
specification that is not generally considered appropriate.
4. Approved tires: Treaded racing tires or approved street tires with a
suitable speed rating. Grooved bias-ply slicks with SVRA approved tread
patterns. The approved tread patterns are: Dunlop CR-65 & CR-82; Avon All-
weather; Goodyear G-12. While exact size and aspect ratio are not specified,
entrants must ensure that tire choice is appropriate for the car during the
eligibility period.
