OS Giken Nissan Skyline GT-R R4C quad-plate clutch for early BNR32
For the most extreme drag racing applications, while still retaining street drivability, the OS Giken R4C clutch is unbeatable. Power handling is well in excess of 1000hp. In fact it has been tested in drag cars with over 1200hp with no slip apparent. However, due to the multi-plate design, it is still surprisingly drivable for street applications, retaining the same clamping force as the R3C design. Like the R3C it uses a lightweight chrome-moly flywheel, gold-anodised billet aluminium clutch cover and the necessary bearing/carrier set or pull-push converter kit as required.
