The NISMO Light Weight Flywheel (part number 12310-RSR41) is the chromoly disc specified for the BNR34 RB26DETT with the six-speed gearbox. It is not interchangeable with the 12310-RSR21 flywheel used on earlier GT-R models.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eNISMO lists the unit weight at 8.31 kg versus 14.24 kg for the genuine flywheel, with inertial weight reduced from 2.615 to 2.097 kg·cm\/sec². The disc is machined from SCM440H chrome-molybdenum steel, marked with the NISMO logo, and uses factory-style ring-gear chamfering so the starter pinion still engages cleanly. Flywheel bolts and a press-fit dowel pin are included.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eThis flywheel was developed for NISMO single-plate clutch covers and discs. Paired with that hardware, rotating inertia drops far more than a flywheel change alone and engagement becomes more direct than a dual-mass setup. It can be used with an OEM clutch layout, but NISMO recommends it with the matching sports clutch kit. Lighter mass usually brings some extra gear noise or resonance at idle compared with the stock dual-mass unit.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eAt Terra Firma Automotive, we supply this genuine NISMO Light Weight Flywheel as the correct BNR34 six-speed upgrade for RB26DETT owners who want faster engine response without a generic aftermarket disc.
