You Have Asked Two Questions (archive)

Best arrangement for the street is stock everything. I autocross - a lot - and the more I autocross the less I care what I have on the street. You just can't tell, and you are NEVER at the limits, which is the only place a change would help you.

Now, for autocrossing. My car is slightly different from yours (M Roadster), but still has an M3 front suspension.

Get crash bolts for the front. Sorry, no p/n, search the archives. Parts guys will just stare blankly at you. $3 each, one for each side. They will allow you to get .4 degrees more negative camber. Have an alignment shop do this - they got .2 degrees more than I could alone.

Second, set your toe to ZERO. I ran toe out last year, as that is the usual recommendation. But at a test & tune this spring I found that zero toe was 1.6% faster on an autocross course. This was recommended to me by a BMW racer on Team.net. I could not feel any difference.

And you want an adjustable front sway bar. My Dinan was just $130, but it will be different for your car. Set it to full soft, which is the furthest hole towards the end of the bar. I ran at full stiff last year, but the test & tune showed full soft (the common solution to understeer) to be faster.
