99-18 YAMAHA YZF-R6: Galfer HH Sintered Ceramic Brake Pads (Front G1375) The G1375 compound is the result of many long days at the race track and on the brake dyno. Based on Advanced Ceramics, this compound is meant for the track. It offers very fast heat recovery for more consistent braking which in turn, gives the rider more "feel." This is the pad of choice for most racers at the top of club levels and AMA contenders. These pads are very easy on rotors since they do not have the same levels of metallics in them like many O.E.M. and after market brands.
