High performance brake pad for drivers in search of maximum braking efficiency and performance. The DS2500 pads have a constant friction coefficient of 0.42 at all temperatures (from 20°C to 500°C), meaning you won't need to build up and maintain high operating temperatures for efficient braking. Formulated to Minimise disc wear. Low in compressibility for a firm pedal feel. Extremely versatile, these pads are ideal for track days, circuit, rally, hill climbs....Pad dimensions: 100.7 x 46.4 x 12,5 mmBrake pads for the following calipers:- ALCON PNF0084X284- JFZ / Sierra Mini GN dual- Thickness 12.4mm- Thickness 12.4mm- Wilwood Dynalite c/pin- Thickness 12.4mmThese FERODO brake pads are equivalent to the following models:- ALCON PNF0084X284- ALCON PNF0084X284.4- PFC 7752
