Yet another offset question

[JRowe]

I have 16x7 ssr wheels with a 37 offset. Obviously, a 15mm spacer would work well with a 225/45/16 = 22mm offset. However, I may be able to get 20mm spacers for a REALLy good price. Would I run into too many problems with the fender lip and fender liners. It would be on offset of 17mm with 225's. I'm thinking it probably won't work even if I roll the lip. Any thoughts?

I run 225's on 15x7 et17 Kosei's You will need at least 2.5 degrees negative camber in front and rolled fenders to clear if you are low.
