IX. SHOWROOM STOCK

The Showroom Stock (SS) category is intended to provide competition for mass produced stock automobiles. Kit cars and limited
production cars modified by the manufacturer or aftermarket companies and resold through authorized original OEM suppliers
(Saleen, Callaway, BMW Motorsport, Ford SVT, etc.) are not considered Showroom Stock.

The cars classified are the base model unless otherwise specified. Gray market and limited production models will be classified at the
Event Stewards' discretion. No updating/backdating allowed.

Cars are classified in five (5) classes based on performance potential, using the SCCA Showroom Stock specifications as a guideline.
Cars not listed in the SCCA Showroom Stock classification will be reviewed by the Event Stewards during Tech Inspection to insure
proper classification.

The competitor may be required to provide a factory shop manual of the competing vehicle's model and year to aid the Event
Stewards in determining what is the "as delivered" configuration. Should a vehicle's as delivered configuration be subject to
investigation via a protest, track record inspection, or other inspection deemed necessary by the Event Stewards, the competitor must
provide a factory shop manual or risk disqualification or bumping to the appropriate class as deemed appropriate by the Tech
Inspector/Event Stewards.

Showroom Stock automobiles will compete in an "AS DELIVERED" configuration with preparations and modifications allowed
ONLY as follows:


CAR INTERIOR

1. Accessories, gauges, indicators, and/or lights are permitted.

2. Drivers' seat may be replaced with an aftermarket seat.

3. Steering wheel may be replaced with an aftermarket wheel, provided the diameter remains the same as stock.



EXTERIOR -- WHEELS AND TIRES

1. Any type wheel may be used provided wheel size (width and diameter) remain stock. Wheel offset may be +/- 5mm
from stock. Cars delivered with 12 inch wheels may use aftermarket 13 inch wheels with a maximum width of 5 inches
that fit within stock fenders. Cars delivered with wheels greater than 17 inches in diameter may use wheels that are 17
inches in diameter, provided they are the stock width.

2. Wheel spacers are not allowed.

3. Tires shall be of "as delivered" construction, DOT approved with no undertread showing (for safety reasons), and either
be listed in THE TIRE GUIDE or be available in three or more rim diameters.

4. Any size tire that fits on the stock rim is allowed provided it meets the following:

a. The tread fits within the stock fender and wheel well (without modification) as measured by a vertical line dropped
down from the fender lip while the car is at rest on level ground with the wheels pointing straight ahead.

b. The rim width used is among the rim widths recommend by the tire manufacturer for that particular tire size.

1. Any brake fluid, brake pad and/or shoes may be used. Braided stainless/teflon brake lines may be used.

number of shock absorbers must remain as stock. Shocks incorporating load supporting devices and/or external
reservoirs are prohibited.

Modifications of any type, including additions to, removal of or non-stock replacement of the catalytic converters, thermal reactors, or any other pollution control devices are not allowed and the system must be operable.
