#737, "RE: check out porterfield r4s pads" In response to In response to 3
I've got the R4S with my AEM kit. So far I am very happy with them.
I ordered some KVR carbon kevlar rear pads from SP Motorsports (www.spmotorsports.com). I'll be picking them up from UPS hopefully today. Will post on my evaluations of them when they are installed.
