The 034Motorsport 380mmx36mm 2-Piece Floating Front Brake Rotor Upgrade for BMW G8x M3/M4 is a complete replacement brake rotor, designed to work flawlessly with the factory front calipers. Upgrading your front rotors will increase overall braking performance in street, track, and HDPE driving conditions, as they keep your brakes cool and strong all day long! Weighing in at approximately 30.0lbs, our lightweight design retains proper thermal mass in the rings to adequately capture heat while utilizing 72 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat. Advantages of J-Slot over Drilled Rotors: Typically, OEM rotors that are drilled are first cast and then drilled, which creates additional stress points that weaken structural integrity, making them more prone to cracking as they go through heat cycles and wear over time.
Fits: BMW S58: M3 (G80/G81), M4 (G82/G83), M2 (G87). Confirm your exact car with us before ordering.
