Porterfield Street/Autocross/Race brake pads

from $89.00

Carbon Kevlar pad sets available for the Alfa Romeo GTV6 / Milano 75 and Alfetta GTV and Alfetta Sport Sedan Chassis.

Choose from the following compounds:

R4-S  • This is a max performance street compound pad that's better than stock while being very easy on the rotors and has a very low dust formula and long life. Good modulation and feeling from these.

R4-1  • A friction level above the R4-Street and for race use, this pad heats up quickly and is great for autocrossers. Also rotor friendly. Expect more dust and noise than with the R4-S.

R4  • Full race ready pad for track days and autocross events. Has great modulation, optimum heat range is 450-1200 degrees. Recommended that street driving be limited to a minimum on these pads. More noise, dust and rotor wear than R4-S because this is an aggressive race compound and in the high bite category of compounds.
