Porterfield Street/Autocross/Race 4C pads

from $130.00

Carbon Kevlar pad sets available for the Alfa Romeo 4C Coupe & Spider in these 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.

*Note: Porterfield pads are a high performance pad, and do not come with wear sensors. These can be installed on the Alfa 4C with no issues and no sensor warning lights. Just tie off your plugs so they are out of the way during install. There are No Returns accepted on any Porterfield pads - so choose carefully and be sure and ask first if you have any questions about compounds.
