I was considering buying the BBS LM - maybe 18" because i want to drop the car (eventually Bilstein PSS9s) and don't want to have tire rubbing and have to roll the fenders. I can't seem to find the stats on the rims. Such as how much does it weigh. I was thinking about putting 255 in the back but what would be the sidewall height? Maybe I can get some feed back and which way to go. This is for a 2002 330ci w/ sport package.
