I've been around the forums a while, I know for the most part what fits and what doesn't, but this I am not sure about. Right now I am running RPF1s 17x9 +45 all around with 245/40 Advan AD08s. The fenders are rolled, tab relocated, and some of the fender liner is cut. I track the car and don't think it rubs on even hardest compression. I am running around -3 camber all around.

I have a pair of Wedssport TC105N 18x8.5 +32 sitting in my room. My question is, would those with 225/40/18 would work if I got another pair in 18x9.5 +35 and 255/35/18? Or stretch a 215 and 245? It seems pretty borderline to me. Or should I just sell the wheels?

 

The 225 and 255 setup should work fine. I have 10 +38 in the rear and run -3.5 camber so you may want to see about pulling the fender ever slightly.

 

You should be able to get it to fit all the way around. May have to flare the fronts a tad or the rear depending.
