Detailed Product Description

The 830-31144R rotor from Dynamite Friction features a vented design that helps maintain optimal braking temperatures by allowing air to flow between the rotor surfaces. The drilled and slotted surface pattern is directional, which aids in channeling away brake dust, gases, and water, improving overall braking consistency. The rotor’s nominal thickness is 30 mm, with a discard thickness of 28.4 mm, ensuring a long service life before replacement is necessary. The rotor’s hat is finished in Geospec silver grey, providing corrosion resistance and a clean appearance. Additionally, the rotor includes a rust resistant coating to further protect against environmental wear.
