Clutch Masters lightweight steel flywheel for the RB25DET-powered Nissan Skyline (Japan-spec motor and transmission). CNC-machined from 1045 steel billet in the USA, zero-balanced for true rotation and black-oxide coated to resist corrosion. Shedding rotating weight helps the inline-six rev more freely. SFI 1.2 certified and built to run with a Clutch Masters FX-series single- or twin-disc clutch.
