Im getting a set of ADVAN RS Wheels 18x9 wrapped with ADVAN Neova 265/35-18
What offset could I get to concave the most in the middle but still clear the brembo brake calipers safely?
Anyone know? Please help.

 

+29 offset

 

I think you could clear the brakes with the +20 or +22 or whatever they come in but that would require quite a bit of fender work. I would stick with the +29s personally. Search around for them and see how well they look. Many pics of those wheels in +29 on here.
