PARAGON 2-Piece Rear Rotors – Toyota GR Supra (Mk5) / BMW Z4 (G29) / M Sport (G-Series) – 345 x 24mm
A 345 x 24mm two-piece rear rotor pair for the Toyota GR Supra 3.0, BMW Z4 G29 and M Sport G-Series BMWs. Each rotor weighs 7.55 kg, saving about 0.77 kg a corner over the factory part, and the floating design resists heat distortion during spirited driving and track days.
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: A direct bolt-on rear replacement with no modifications; BMW models need the factory M Sport rear brakes. 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.
Features
- 345 x 24mm rear pair, 7.55 kg each (about 0.77 kg lighter than OEM)

- CM-250 high-carbon alloy cast iron rings, heat treated to relieve stress and CBN machined flat
