I’m selling a set of Porterfield R4-S rear brake pads. The R4-S are a replacement for the D1004 rear pads, found on some later-produced 2003 and all 2004-2005 WRX models. These pads have never been installed on my car and are still brand new.
Although Porterfield call these pads carbon kevlar, I believe they’re a ceramic compound. The R4-S is a good pad for daily-driven street cars and produce a low amount of dust and noise. They’re also easy on the rotors, which may be important for some. If you’re interested in more information on the pads, take a look here.
Send me an e-mail if you’re interested in buying. I’ll ship anywhere in the US, PayPal only please.
