[QUOTE="davidd, post: 120254, member: 1177"] I would not buy linings from a supplier that could not cite the exact model of the lining and the coefficient of friction, both cold and hot, of the linings. There is no other way for you to document what works best for you. This is often done in letter code. The Green Gripper is "GF". The letter codes work as follows: E=0.25-0.35 F=0.35-0.45 G=0.45-0.55 H=0.55-0.65 If a lining is labeled "GF" like the Green Gripper it has 0.52 cold and 0.43 hot. The first letter is the cold number and the second letter is the hot number. GF is fine for the street. If you were racing, you might want GG or higher because you need the hot performance to be pretty better than average. HH linings are available, but they require lots of heat and are usually too unstable for normal use. If you have installed disc brake pads on anything the letter code is often displayed on the edge of the friction material in paint. David [/QUOTE]
