SCCA National Solo II® Preparation
Categories
There are several levels of car preparation starting with
"stock" and going to "modified". The SCCA defines what
modifications are allowed in each preparation category. Within a
category of preparation there are several "classes" of cars, which
are group by similar potential within that level of preparation.
The preparation categories are:
- Stock Category (AS - HS, SS)
This category of preparation includes most mass-produced vehicles,
which are normally used on the public roadways. The stock category
allows minor additions, removals, or changes of equipment.
- Street Prepared Category (ASP - FSP)
This category of preparation includes all of the vehicles eligible
for the stock category but allows more modifications in addition to
those allowed for the Stock category. In general a Street Prepared
could still be driven and licensed for street use and may appear
only slightly modified (interior still in place). Generally
updating and backdating of components from an earlier/later year of
the same model is permitted.
- Prepared Category (BP - GP, XP)
The prepared category allows modifications to build a high
performance car which would not normally be driven and licensed for
street use. This category also includes cars prepared to production
club racing rules. Some modifications for Prepared are not allowed
in Street Prepared and visa versa. There are also minimum vehicle
weights specified for all cars.
- Modified Category (AM - FM)
The Modified category includes formula cars, kit cars, and
production cars modified outside of the other categories. These
vehicles are intended solely for competition.
- Street Touring Classes (STS, STS2, STX, STU, SM, SM2)
The Street Touring Street Tire class includes cars with
Stock category allowances and additional popular street
modifications such as lowering kits, wider wheels, some bolt on
engine modifications, etc. The STS (4 seater cars), STS2 (2 seater
cars), STX and STU classes must compete on DOT rated street tires
with a wear index of 140 or greater, while the SM (4 seater cars)
and SM2 (2 seater cars) classes have much more liberal engine
allowances and may use any (race) tire so long as it carries a DOT
rating.
Street Tires: any DOT rated tire with a wear index of 140
or great.
Novice: Anyone who has entered less than 6 events in the
prior 12 months AND has not received a trophy in any class.
