yeah my sister has a e46 318i.
would be good with more power, just too heavy and gutless with that engine.
if it were a 225i...........
yeah 2/3rz's are pretty heavy though. the power would almost make up for it if you have stiffer springs. for e.g, the ke's with sr's and 3s's kind of make up for it with stiffer rates. but really, im a novice when it comes to sussy, all i have is cutties and good shocks!
