NASCC - Chevette Class Rules,
2004 to date (Version 2004
written Nov. 2003)
The class will offer close
competition, relatively low vehicle cost, and minimum car preparation
effort. The class will develop driving
and vehicle preparation skills, while maintaining close competition for both novice
and veteran racers alike.
Eligible
vehicles are Chevette/Acadian/Scooter/T1000 built between the years of 1976 to
1987. All parts may be interchanged
between all years with the exception of specific individual items as outlined

between all model years. Rear mud flaps,
extending to within 4" from the racing surface are required.
Suspension
must retain all factory stock components and not be modified. Factory adjustable components may be adjusted
to improve handling (e.g. Caster, Camber, Toe, etc.). Cutting and heating of coil springs to alter
ride heights is allowed. Shock absorbers
are to be stock, or stock replacement units specific
to the models listed (No Racing Shocks Allowed). Brakes must be fully functional and not be
modified in any way. Emergency brake
must be connected to both rear brake assemblies, and must not influence either

the bumper face or interfere with bumper function. Bumper corners must be tied to body panels or
cleanly capped in order to control bumpers hooking with other vehicles.
Must be original equipment only ratios between 2.71:1
and 3.8:1. The 4.11:1 gear ratio (rare) is NOT
allowed. No traction improving
modifications allowed (No welding or shimming of spider gears).
Factory
stock, original equipment, (13" x 4.5") steel wheels must be used (No
mag wheels allowed).
Spec.
Tires only (Bridgestone Blizzak P175-70R13, “WS-15”
or “WS-50”) unless otherwise defined in the sub-regulations.
Western
Canada Motorsport Association (WCMA) cage
specifications must be followed. A
complete spec roll cage must be used.
Roll cage must be padded near driver's head, left side and knee region. Spec cage kit is available. A ¼ inch access hole must be drilled in the
vertical tube adjacent to the B-pillar.

added to improve traction and/or handling.
Ballast should be located in rear seating area or between rear rails or
in spare tire well. Ballast must be securely
mounted to vehicle. Ballast must be
safe, secure and removable. Concrete is NOT
an approved method of ballast. Ballast must be behind driver. Securely
mounted ballast may be added to the under-side of the vehicle between
differential housing and floor providing it does not extend more than 30 cm
from the center of the differential to either side and
not more than 30 cm forward from the centerline of the rear axle. Ballast type
and location is subject to race organizer’s approval.
Must
remain in stock location and be secured with a metal strap or bar, using minimum
5/16" threaded rod or bolts on either side.
Must
be Factory stock or stock replacement manifold only. Exhaust manifold must remain unmodified

reinforcement mounted in any vertical body surface, including any surface
covered or enclosed by original body panels. “Self-expanding” foam may be used
inside rear vertical panels up to the stock bumper height. A short piece of
roll bar tubing may be added to the roll cage by the driver’s left leg to
reduce the left front wheel intrusion in the event of a hard impact to this

The
Chevette regulations are a sub-section of the general Ice Race Rules and
Regulations as defined by WCMA and distributed through the local club, NASCC.
These
WCMA regulations should be consulted from the WCMA web site and specifically

In
order to maintain close competition, the starting grid may be fully inverted
according to point standings and race finish results. Races are to begin from a standing
position. (Standing
start).
For
Chevette Races, it is expected that the top 6, top 10, top 15, or top 50% may
be inverted. Class size, track design
and weather factor in the decision. For
a class size of less than 16 cars, full inversion is expected. For a class size of greater than 25 cars, a
top-N car inversion is expected (N = 6, 10, 15…).
Warnings
or vehicle exemption may result if an illegal performance enhancing
modification is found. Vehicle log-books are encouraged to be used for
reporting any problem areas. Random technical checks may be expected.
