Spec 89-94 Skyline R32 / 93-98 Skyline R33 Push Type Super Twin ST-Trim Clutch Kit

The SPEC Super Twin ST-Trim Clutch Kit features a unique dual-plate design, utilizing a high-performance sprung center hub for each disc. This setup is engineered to handle significantly more torque than a single-plate clutch, making it a robust choice for modified Skylines. The ST-Trim designation indicates a specific friction material blend chosen for its balance of holding power and drivability, aiming to reduce chatter and improve engagement feel compared to more aggressive twin-plate setups.

This clutch kit is built around a billet steel flywheel and includes two high-performance friction discs, along with a heavy-duty pressure plate assembly. The dual-plate configuration spreads the clamping load over a larger surface area, which helps manage the extreme forces generated by higher horsepower engines. SPEC has designed this kit with a push-type release bearing system, which is often preferred for its straightforward integration into the factory or aftermarket clutch hydraulic system. The sprung centers on the friction discs are crucial for absorbing drivetrain shock and vibration, contributing to a more comfortable driving experience, especially in daily driving situations.

When installing this clutch kit, it's important to ensure all mating surfaces are clean and that the flywheel is properly torqued according to manufacturer specifications. Because this is a twin-plate system, proper alignment of the clutch discs during installation is critical. This kit is intended for enthusiasts looking to significantly upgrade their Skyline's drivetrain capacity, and while it offers improved drivability for a twin-plate, it is still a performance-oriented component. Consult the included installation instructions for detailed guidance.
