Pagid RST Red brake pads are formulated for iron discs and are an upgrade for StopTech C43 and ST43 calipers with a wide pad area. This is the Wide Annulus pad shape with a wider (taller) pad - 51mm vs 43mm.

The RST4 compound is a semi-metallic resin bonded material containing steel fibers. This compound has a low but stable torque output across all temps. Bite and modulation are strong but the lower torque output often puts this on the rear axle to custom-tailor braking bias, especially on front-engine GT and touring cars.

Pagid RST4 Characteristics
+ medium friction level
+ very good fade resistance
+ stable torque output across all temperatures
+ good pad wear with very good rotor wear
+ high initial bite

Front and rear brake compounds should be closely matched to maintain brake balance. Never upgrade one axle and not the other.
