I have S-04s in 305 rear and 265 front. I know this is not a square set up but the tires cover the rims perfectly. Attached are my alignment specs. I am dropped on Teins just like Fuct, and I have rear camber arms and tow bolts!
I don't think you can get a better tire for the money. I pushed them very hard this past weekend on a mountain run and they performed better than I had expected, especially with a 170 more whp!
