Which Class

[Jean]

I've got to disagree I run my 87 325is in street mod and usualy run in the top three. E30's are really competitive in SM if you really learn how to run your car and yours can compete especially with the set-up your running

Maybe on a local level, but nothing more than that.

^True, maybe if you had a built to the hilt S54, 315/30/17 slicks and really knew how to drive you (Like Erik Strenaliks or Andy Hollis able to drive) you might be able to trophy at Nationals (ie top 1/3, right?)

But the E30 just isn't going to put down power like the STi's and EVO's. Even with custom adjustable rear trailing arms and all, which I plan to do as well.

Would the M3 offset front control arm bushing be illegal? And what about roll center adjuster? Probably not...

16.1 H --> "Subframe bushings may be replaced with bushings of any material as long as they fit the original location. Offset bushings may
not be used."

Why are you looking at the subframe section when asking about CABs? I don't have the rule book saved on the comp at home, only at work, so I'll have to look tomorrow.

I don't know... haha

Ur right, I must look at the right section! lol

And with SM, you have to remember to look back through Stock, Street Prepared and Street Touring as these encompass all the allowed modifications, PLUS what is allowed specifically by SM.

I went back and found it in Street Touring, you are allowed to use M3 CABs.

Thanks!

Il will also do some solosprint. Sorting out what will be the best build for me will be a long rules study!

Well you're in SM already, so just build the car to the extent of the rules which basically means you can do anything to the suspension except modify pickup points or offset the subframe.

Custom control arms, poly bushings, eccentric RTABS (because they are mentioned in the factory manual to repair crash damage) are all legal.

I'll be interested to see what you do, as I'll basically be building my car to the extent of the SM rules, except for some of the weight removal as I still want a car that doesn't suck completely to drive on the street.

Look at my thread in the members ride section! We seem to have a similar project!

Do you have a thread on your project?
