the BBS LM's on my car are 18x10 +20 with 275-35s and they sit well, but the tyres are quite close to the rear strut lower spring cups, and also quite close to the front inner wing plastic at the front bumper on full lock. With 9.5s dependent on tyres you should be fine.
can some one put som pic up??? im in the same dilemma im get the Volk Racing SF WINNING WHEELS IN GLOD WITH SILVER LIP. The size i was thinking 19x9.5 but im not to sure for the offset or the tires size. Has any one got some picture i can see
