ive got some legend calipers/carriers with braided lines and endless pads, 1 caliper i bought brand new and other i had rebuilt at same time just for peace for mind, worked superb on track (havnt used these pads on track so less than 10k road miles) but used slightly lesser project mu model on track and was as good as dc2's ive taken round track with aftermarket kits, you could just utilise your own discs then
