Description
This is a pair of drilled and slotted brake rotors for a TR3B (10 3/4 Disc), TR4, TR4A, TR250 and TR6. Give your car the best braking possible, made by TRW. Perfect fit and looks great. Cross Drilling to provide multiple paths to disperse built-up heat and gasses. The TRW cross-drilled holes are bi-angle chamfered at the rotor's outer surfaces to help reduce the cracking caused by repeated, high stress, high temperature brake applications. As for the slots they actually allow the discs to expel built-up brake dust and gases that are generated every time the brakes are applied. Cross Ref.# 586-645, DF7306/7, DF7306-7, DF73067, 209327
