I have not used this pad/rotor combo, so I cannot speak to it, but just wanted to throw something different out there. And this is not meant to insult or anything, but the more aggressive the pads (i.e. race style pads) the more you need to be smooth on the brakes. Its not uncommon for especially a novice racer to panic and stab the brake lever and launch themselves over the handle bars (I haven't launched myself but definitely had an oh shit moment when the rear gets up and starts coming around). I try my best to follow what Ken Hill preaches, with less brakes for longer and first and last 5% stuff.
And on a side note I have the GPFAX pads with stock rotors and I love them.
No offense taken, I'm not newbie but I'm not expert. The problem I was having is when getting down to that last 25% pull i.e. From slowly "smoothly" pulling the lever in that last portion was unsettling. I wasn't "grabbing brake" and thinking oh shit. As I would come into the braking cones as I always have everything is fine but as I reach that last bit of pull it feels almost like a shimming of the rotors as in warped. But it wasn't doing that in any other application, in fact at one point I think I had my first experience of "brake fade", not sure but I felt for a split second I was at max braking then nothing.
Not arguing and I really do appreciate the feed back. I've got the new pads ordered I'll report back.
