I got mine disc's calipers and pads complete from Tim (golfworx) a while back, basically brand new. I'm lead to believe ATE had a part in something, but I'm noot sure which part (or parts) or what pads I have, so I can't really help you on that one. All I know is that they're a hec of alot better than the stocks, and I havn't even really pushed/used them yet. (ie, in enthusiastic driving purposes)
