Hawk Performance's HPS (High Performance Street) compound is a ferro-carbon friction material built to raise brake torque over a stock pad while staying civil on a daily-driven, street-legal car. Hawk publishes it as delivering increased stopping power with a smooth braking feel, consistent brake release, and wear characteristics that stay gentle on rotors. It is a street compound, not a race compound.
The letter before the decimal in a Hawk part number is the compound, not the axle: the F in HB126F.505 means HPS. The number after the decimal is the pad thickness, 0.505 in. Hawk lists the HB126 shape as a front pad on the 1965-1973 Chevrolet Corvette and as a rear pad on the 1966-1973 and 1994 Corvette, so check which end of your car you are ordering for. Bed-in is required before normal use; follow Hawk's published installation and bed-in procedure. Not compatible with carbon ceramic rotors.
