What is the primary advantage of the sprung, multi-plate clutch disc in this kit?

The sprung hub in the multi-plate disc helps to absorb torsional vibrations and shock loads. This can make the clutch feel a bit more manageable and reduce drivetrain stress, especially in vehicles with significantly increased power output.

What does the 'Stage 3+' rating signify for this SPEC clutch kit?

A Stage 3+ rating means this clutch is intended for vehicles that have undergone substantial performance modifications and are producing considerably more horsepower and torque than stock. It's built to handle these higher power levels reliably.

Does this clutch kit include a new release bearing and pilot bearing?

Typically, a Stage 3+ clutch kit from SPEC includes the pressure plate, clutch disc, and release bearing. It is recommended to check the specific contents of the ST623F-870 kit to confirm if a pilot bearing is also included, as it is often a separate component that should be replaced during clutch service.

About this part

Product Details

This SPEC Stage 3+ clutch kit uses a sprung, multi-plate design, which is a notable choice for handling significant power increases. It's built for the 2.0L Turbo engine found in the 1990-1995 Toyota MR2 and the 1990-1994 Celica All-Trac. The sprung hub helps absorb some of the shock and vibration that comes with a high-performance clutch, making it a bit more manageable for daily driving compared to a solid hub setup.

The Stage 3+ designation means this kit is designed for vehicles that have seen substantial modifications, pushing well beyond stock power levels. It features a heavy-duty pressure plate and a high-performance friction disc that can handle the increased torque and heat generated by a tuned engine. The inclusion of a GM 26-spline input shaft means this kit is specifically configured to mate with a GM transmission, often chosen for its strength and availability in high-performance builds. This setup is ideal for those looking to put down serious power reliably.

When installing a clutch kit like this, it's important to ensure all mating surfaces are clean and that the flywheel is in good condition, or ideally, resurfaced or replaced. This kit is a complete package, typically including the pressure plate, clutch disc, and release bearing, though it's always a good idea to confirm what's in the box. Proper break-in according to SPEC's instructions is crucial to ensure the longevity and performance of the clutch system.
