I was wondering if the info you gave me was from personal experience or from what others had told you. On the thread I started for "ITR mods for a track day car", you said 225/50/15 would fit on 15x7 wheels with a 38 mm offset. As this is the tire size you and I would both like to run, I would also like to know if it really fits before I order the wheels. When I spoke to Tire Rack, they said a lot of people order just one wheel/tire combo to try out the fit and he said they will accept return if the tire is unsused. Client of course pays shipping both ways. As you and I are both basking in the snow and wanting to run at Mosport, customs clearance is a bit of an issue, but we can wait for the info. I also did a search on a few boards but was unable to find an answer. I also checked out Kosei's Japanese website and they have a new lighter version called a Kosei K-1 Racing TS version, just 4.9 Kg for a 15x7. I also found out that the Buddy Club P1 Racing is the same wheel as the Kosei K-1 currently being sold by Tirerack. Check out the site www.wheelspecs.com and search for wheels from 15x7 min to 15x7 max and less than 14 lbs. Then you can look at available sizes, offsets and weights.
