Application to Nissan GT-R (R35) 2008-2011 The mounting bell of the kit is made of 6061 T6 aerospace aluminum alloy, and the hard anode makes the strength even better. The disc, made of high carbon cast iron, is the same specification and material as a professional racing car. Because of the larger friction area of the brake disc, we have compared with the 30-48 straight lines or lines sold vanes, through CFD and stress analysis, we developed 72 curve vanes design, which has better heat dissipation and hardly distortion can effectively increase surface strength (especially for large brake-area discs). Also, the excellent design of a floating system of Anker Brakes can stabilize and maintain the brake disc in the best position under severe temperature changes in order to prevent overheating and distortion of the disc. Once the Anker Brakes system is installed, simply replace the disc in the cast iron section as necessary. When used with high-performance brake pads and brake fluid, you will have a truly amazing driving experience.
