Viperi, not going to thread jack, but I really don't think you're getting that great a deal. I know you dont believe me when I say R1 Premium and Centric Stoptech are the same, but you'll see what Centric part number comes engraved on your rotors.
I just did this mock up for another member for his 2007 FX35. This was for Powerstop Rotors Drilled / Slotted (R1 Premium d/s) and StopTech Street Performance Pads was $467.34 before shipping and $525.01 including shipping.
From your Group Buy Information, the deal it ends up being - $495 before shipping for StopTech performance pads and "R1 Premium Rotors d/s". Maybe you can work with them to get free shipping for our members?
