Such a car should legally be running in Street Modified, but might be allowed locally to run in G Stock (or STX), where the car will at least have a chance.

In addition to the Evo and the STi, look to see BMW M3s doing well in STU. The M3s get to mount wider tires, and they are lighter. The Evos and STis will have a bit more power.
And because participation is low, you may find cars which are not "natural" STU cars running STU hoping to "cherry pick" a class win. I've seen a few Subaru WRXs which are legal for STX running in STU.

In my region STU has not taken off like STX did. I have tried it, and I don't think the stock clutch in the EVO could handle the allowed power mods over a full season of competition. To be honest, I would prefer to stay where I am (ESP) running street tires just so I could upgrade the clutch.

The fact is that the M3s are allowed by STU rules to run more tire than the AWD cars, and the E36 M3s are lighter than Evos or STis. Lighter car, more tire. The Evos and STis can probably beat the M3 on acceleration and can probably put that power down earlier on corner exit. But the M3 will carry more speed in the corner due to the wider, more lightly loaded, tires.

Food for thought, all that guy in the BMW did was to add coilovers to an otherwise stock M3.

Yes, the rules can be tricky, my region runs Street Novice for first year competitors based on PAX. So that's fun for me! But I'm going to pull out of that and put my car into SM, where it belongs. Unfortunately a $45 hallman MBC puts you into SM. My SM region isn't TOO tough; several WRXs with coilovers, utecs, etc., camaros with big tires, and a talon with a RRE suspension and victoracers. They don't care what you have done with your car unless you pose a threat

In SM, drivetrain, suspension, and brakes are all unrestricted. (Well, suspension must use the stock attachment points.)
Modifications which don't provide a performance advantage are unlikely to be protested.
With all of that out of the way, there are really only two areas that provide any significant performance increase and where an SM car owner might try to cheat:
- Illegal chassis modifications. If they're big enough to make a difference, they're big enough for a competitor to spot them.
- Illegal weight reduction. Again, if it's big enough to make a difference, it's big enough for a competitor to spot it.

I think the Cams, boost controller, etc. put you in SM.... That is where I am...if you are like me and are just doing it for fun and to enjoy your car then it really does not matter what class you are in...Just get in the correct one and have fun...

Jack, you are right, E46 M3 is actually excluded; the E36 M3 is included
