Front disc for 17 inch wheels

A 13” rotor is about as big as you’ll be able to go, and depending on the kit/calipers there may still be some 17” rims that don’t fit.

I have doctordiff’s 13” brake kit with the “cobra style” calipers, it works with a 17” rim. I use a spare tire from a G35 that is a 17”, fits fine.
