This is a set of four high performance brake pads for the front of any model year Fiat Bertone X1/9, Fiat 124, 128, Yugo and Lancia Scorpion. These are made by a respected performance brake company and are the full race version of their Carbon/Kevlar racing pads, used by Midwest Bayless on all of our competition cars for nearly 10 years. Excellent stopping power for stock brake applications. 17mm, full-thickness pads with wear indicator. For auto-cross and full race conditions. The R4 friction level will give you an impressive increase in stopping ability.
Note that these pads require modest warmth in the pads or rotors, usually one or two braking applications, to achieve full grip. At "cold" they are similar to a stock street pad.
