Got around to installing my new wheels, BBS LM's (die-forged multi-piece). 19x8.5 front, 19x10 rear. Front weighs 25.1 and rear 25.8lbs (stock 19" GS were about 28 front and 30 rear). Tires on there are Toyo TR1's, not at all happy with them, replacing with Pilot Sports or GSD3's next week. The car really needs to be lowered now as the lighter wheels stand out more than the dark mercury ones did, I'm thinking 2" in the front and 1.5" in the rear? Anyone know how many turns of the collars = 1"?
