PARAGON 2-Piece Rear Rotors – BMW M5 (F90) / M8 (F91/F92/F93) – 380 x 28mm
A 380 x 28mm two-piece rear rotor pair for the BMW M5 (F90) and M8 (F91/F92/F93). Each rotor weighs 10.0 kg, and the fully floating ring with an aluminium hat cuts unsprung weight and copes better with heat than the factory iron rotor in hard street and track use.
Two hat finishes are offered. Mil-Spec Hard Coat (clear) anodising keeps its colour under track heat and is the one to pick for circuit work. Mil-Spec Black Coat (dyed) anodising can discolour above 260°C, so it suits street and mixed use.
Note: Not suitable for cars with M Carbon Ceramic brakes (option S2NKA). Bolts on with the factory rear calipers; works with the factory calipers, ABS and brake bias, and takes OEM or aftermarket pads of the same pad depth as the originals. Installation by a professional is recommended.

- 380 x 28mm rear pair, 10.0 kg each
