Raybestos — Raybestos RC 1082 Brake Pads, Mustang, GT, Shelby

Raybestos ST42
Lower mu than ST-41 and ST-43. Extremely stable average and in stop output over a wide temperature range. Has been very successful when used on the rear brakes in conjunction with the ST41 on the front. Best high-temperature wear of all their materials.

Raybestos ST43
Excellent wear rate on rotors and pads. Friction level between ST-47 and ST-42. This is the most popular compound for HPDE, Open Track and Endurance racing.

Raybestos ST45
Lower friction level than the ST-47. Slightly higher friction level than ST-43 while maintaining good rotor and pad wear. Could be used as a great rear to compliment the ST-47 compound.

Raybestos ST47
Has the highest friction and torque available to date. It has been engineered for long-lasting extreme heat situations and maximum rotor life. If you are looking for the most advanced-performing road race brake pad, that will simply out perform all the rest, this is it.
