With my new B8's, I have a little bit of strut clearance left (2-3mm), and now considering replacing my 10mm spacers with 8mm spacers. Tire is a little more buried in the fender. Switching the spacers from 10 to 8mm would equate to an ET44 offset (ET52 - 8). This switch would remove my concern with rubbing under hard compression, when Im lapping at the track, going over a curb, etc.

My fenders are not pulled or rolled, and with stock suspension, I had rubbing on front passenger side under hard compression at the track with my square 255/35R18 setup.

I will find out if I rub with my new setup and new Dunlop Direzza Zii StarSpec tires at my first lapping event of the 2015 season next week.

Test fitted the ZII* on 8.5" wheels and it's so close to fitting but under compression is slightly rubbing on the bumper, not the fender.

It looks like I have about 7 or 8 mms clearance from strut to wheel...maybe I could get away an 8mm spacer instead of my 12mm?

ZII Star Specs
8.5" wheels et52
12mm spacers
(Effective et40)
2.5* camber

I think my only two options are to test an 8mm spacer or get adjustable camber plates to see it 3* gets me there...looks like your 3.2* camber is making the difference since all our other specs are almost identical.

Time is really tight for me because I have a track event this Saturday.

Any thoughts/advice? Are there options I didn't mention above to gain a little more bumper clearance?
