A little disappointed here...
Ran EBC GreenStuffs last weekend at Road Atlanta, they lasted for four 1/2 hour sessions and were gone. Pedal feel was poor, and they didn't hold well when hot. I'm running brake ducts to the fronts, using 550 fluid and braided steel lines, so I figure the weak link was the pads. Maybe I got a poor set, but only 2 hours of hard use and they're gone.
Ran KVR Carbon Fiber pads on Sunday, and was impressed. Ran six 30min sessions, no fade, better grip when hot, and still had pads left to last awhile. And could consistently brake 50m further into each corner.
Just some info for ya'll...
