034Motorsport 2-Piece Floating Rear Brake Rotor Upgrade Kit for G8X BMW M2/M3/M4

The 034Motorsport 370mmx24mm 2-Piece Floating Rear Brake Rotor Upgrade Kit for the BMW G8x BMW M2/M3/M4 is a complete replacement brake rotor kit, designed to work flawlessly with the factory rear calipers found on the BMW G8x M2/M3/M4. Weighing in at approximately 18.3 lbs, our lightweight design retains proper thermal mass in the rings to adequately capture heat, while utilizing 36 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.
