Ferro-Carbon is a unique, high-tech family of friction materials developed and manufactured by Hawk Brake for the racing community. Hawk Pads do not require an extensive "bedding-in" procedure. Keep in mind however, that all disc brake pads require a short period of bedding-in before being used to the maximum of their potential.

Black (M): Medium torque racing compound with high initial bite. Black is a good all-purpose, low cost racing pad. Requires gentle initial application of the brake pedal to avoid locking. Recommended for very light sedans, small formula cars, and sports racers. 100-900° F (200-700° F optimal).

Blue (E): Also known as Blue 9012 (the original Blue compound). Medium/High torque racing compound with medium initial bite. The wide temperature range and good brake modulation have made it the #1 pad material for SCCA. Recommended for Production, IT, F2000, Formula Ford, S2000, CSR, and DSR. 250-1000° F (350-800° F optimal).

HP Plus (N): Designed as an autocross (Solo II) and track day (Solo I) compound. Very wide temperature range makes it suitable for all forms of autocross, yet still streetable. Expect an increase in dust, noise, and rotor wear. 100-800° F (100-600° F optimal).
