have used and rate the club racers highly.Mind you, were in a stock evo x.
Have done multiple days on them.
35° ambient temp at sandown, no fade.
Multiple smsp south days, no fade.(did change caliper colour though )
North circuit, no fade.
Best of all, nice and bitey when cold as well.
Temp didn't seem to change this at all, so you get used to it.(I liked it)
Still look near new with the amount of material left.
With a smear of copper/synthetic grease between the pad and pistons, no squeal.
The only downside I see from them, is the cost.
Anywhere from $350 and up depending on caliper.
But, as a dedicated track pad, I don't think this is out of the norm.
Hope this helps any prospective buyers.
