Re: Brake pads (Helmut Ranff)
Most pads with FF rating is good enough for track use. "FF" stands for friction coefficient at .45 to .55 range for high and low temperature operation. There are some "G" ratings out there, but your rotor won't be ble to take it.
track temperature often exceeds 1000F, at this temperature most pads would develop a "glazing" effect which drastically lowers your FE. Ceramic pads were developed for that purpose.
check your pads for glaze if it's advertised as high-performance, if you see it, get a refund.
