FWIW, I have no complaints with StopTech Street Performance pads. Good performance and acceptable dusting imho.

Unfortunately, on Zeckhausen's website, they don't show front or rear fitment for StopTech Street Performance (Centric) pads on OEM 4.6iS calipers/rotors, but it could be worth an email to David to verify.... that is, if these pads catch your interest.
