PARAGON 2-Piece Front Rotors – Toyota GR Supra (Mk5) / BMW Z4 (G29) / M Sport (G-Series) – 348 x 36mm
A 348 x 36mm two-piece front rotor pair for the Toyota GR Supra 3.0, BMW Z4 G29 and G-Series BMWs with M Sport or M Performance front brakes. At 11.3 kg each they are around 1.8 kg lighter than the factory rotor, and the floating ring handles repeated hard stops better on the road or at the track.
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 with no modifications; BMW models need the factory M Sport or M Performance front 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.
