updated rules have been posted

they can be downloaded at the usual location http://spece46.com/spece46-regulations

please note that a few things (tires in particular) are still being negotiated, and some things (exhaust, ecu tune) are under development. but the rest is pretty well defined at this point, please take a look and let us know if there are any questions.

My Ride: 2003 325i
That's awesome.

I didn't see anything in the rules allowing or disallowing converting a 325i to 330i spec. I know this was discussed in the last thread, and I got the impression that it would be permitted, as most of the parts that differ between the cars would be replaced in a racecar build, anyways. Was a verdict reached on that?

The rules should specifically allow swapping legal components (engine/trans/suspension/brakes/etc) into any E46 non-M chassis (coupe, sedan, touring, or flexy cabrio).

They don't have it in their rules but they do have that in their FAQ section on their website.

I do agree though that it should be covered in the rules

I think it would be worth allowing/requiring the ZHP control arms. Pretty much every E46 is old enough that they need new control arms anyway, the ZHP pieces are more robust, don't alter geometry, and hardly cost more. If you're requiring MCS coils and poly bushings anyway, it doesn't really make sense to keep the standard control arms with the nylon ball joints

Regarding 330 conversions, the hardest part would be getting the 330 trailing arm to work.
