My wheels are the standard 17x7.5 SSRs. I'm not sure what the offset is, but they require 5mm spacers to fit.
Alas, I'm not really interested in the 2pc rear rotor. My main reason for buying the 2pc fronts is replacement cost since I've about worn out my stock fronts with heat stress cracks.
The fronts take the huge majority of heat & wear, so those are the only ones I really need.
If the rears were crazy cheap (like $200 apiece), I might consider it for the weight savings and esthetics. But more expense isn't worth it to me for this alone.
