Sorry if this is buried in the thread somewhere but does anyone know if Advan RS 17x9 +45 square requires anything more than a fender roll? And what's the BBK fitment? I'm looking at the brembo 4pot caliper specifically.

 

Depends on ride height, tire size, alignment, suspension geometry modifications, the amount of (negative) poke you're after, how much rubbing you'd accept depending on different driving scenarios... There's so many variables, better to look at the hundreds of setups posted on these forums and other websites and make up your mind from there.
