Will,
Thanks for posting the rule book. I had never seen that, not that I plan on showing a car anytime soon. It seems a bit aribitrary to me that they would allow dealer installed AC, which is also in the accessories brochure, but deduct points for the side stripe kit that so many cars have. It seems like a big jump between stock and the next class (street modified)
STREET MODIFIED CLASS (Up to 15 visible modifications)
Engine - Engine block/Head is to be of same style for year of vehicle (L6 or V6). For example, a L26 or L28 in a 240Z is permitted. No turbochargers, super charges, fuel injection, or nitrous, unless originally equipped.
Interior - Any seats, except race seats, i.e., after-market without seatbelts slots, other Nissan, etc., are permitted. A 4 point mounted roll bar is OK, but not a race ready roll bar with 5 or more mounting points or cages. Stock dash needs to be retained but modifications of stock gauges are OK, if mounted in same place. Must retain interior, any carpet is permitted.
Exterior - Any paint color OK. Any tires and wheels that fit under stock wheel openings (must not protrude past the wheel well by more than ½ inch). Body kits are OK. Any exhaust system with mufflers, driving/fog lights, or suspension modifications are OK.
