The owner of the car already responded but I thought I would add a little info. I am on clubsports but my ride height is a little higher. I have 275/35/18's (Michelin PSS) on 9.5" wheels as well. I have run them at et22 without any rubbing on the fender liners even at full lock. Unfortunately the KW coilover spring showed signs of slight rubbing on the inside (slight black scuff on the spring). I then added a spacer to achieve et15. The inner rubbing was solved but the tire now slightly rubs the liner at full lock. No rubbing during compression while driving. I think the magic offset for a 275mm tire on a 9.5" wheel is probably somewhere in between et22 and et15. I will report back after I experiment one more time with et17. No matter what, negative camber is necessary to run these sizes.
