This flywheel is designed for the VQ35 platform to be used with RPS'S race proven 300ZX Sport and MAX Series clutches. The last flywheel you will ever have to buy. The patented segmented heat shield design will not warp like other common one piece heat shields. All our CYN-R-G flywheels are highly engineered with these benefits like dynamically balanced, crushed Heli coil inserts, stepped dowel pins, and over-sized lock-down bolts that are welded to the ring gear for positive retention. This also features a presicion steel ring for the drive-by-wire pick up signal. Weight: 18 lbs.
