PARAGON 2-Piece Rear Rotors – BMW M2 (G87) / M3 (G80) / M4 (G82/G83) – 370 x 24mm
These 370 x 24mm slotted 2-piece rear rotors replace the factory iron discs on the BMW M2 (G87), M3 (G80) and M4 (G82/G83). The floating ring expands without deforming, keeping the pads aligned and the rear end stable under hard braking, with less heat stress and fade. Sold as a pair.
Two hat finishes are offered. The clear hard-anodised hat keeps its colour under sustained track heat, while the black dyed hardcoat suits street and mixed use but can discolour once surface temperatures pass 260°C.
Note: Suits cars with the factory iron M Compound brakes only; it does not fit M Carbon Ceramic brakes (2NK). Bolts on with the factory calipers, ABS and brake bias, and takes OEM or aftermarket pads of the factory pad depth (D). Installation by a professional is recommended.

- 370 x 24mm slotted rear rotors
