I have Stoptech front stock-sized rotors waiting to go on my WRX. PN: 126.47018SL/R. I did notice that the box has says Centric rotors made for Stoptech. You can probably buy Centric's for cheaper without the Stoptech price/name as I should have, because I didn't know that Centric acquired Stoptech.

Just a little tidbit of info that I didn't know until the Stoptech rotors arrived.
