What is the main advantage of a twin-plate clutch design?

A twin-plate clutch uses two friction discs instead of one. This distributes the torque load across a larger surface area, allowing it to handle significantly more power and torque than a single-plate clutch while maintaining a manageable pedal feel.

What does the 'R-Trim' designation mean for this clutch?

The 'R-Trim' refers to a specific friction material compound that SPEC has chosen for this clutch. This compound is selected for its ability to withstand high temperatures and provide consistent, reliable engagement even under aggressive driving conditions and high horsepower.

Does this kit include everything needed for installation?

This kit includes the clutch discs, pressure plates, a billet steel flywheel, pilot bearing, and alignment tool. It is recommended to inspect and potentially replace other drivetrain components like the release bearing and clutch fork during installation.

Product Details

If you're pushing your 2002-2012 Subaru WRX STi with a 2.0L engine beyond what the stock clutch can handle, it's time to consider an upgrade. This SPEC Mini Twin R-Trim clutch kit is built for those who demand more from their drivetrain, especially when dealing with significant power increases or track use. It's designed to handle the stress of high-performance driving, offering a robust solution for a more reliable and capable clutch system.

This clutch kit features a mini twin-plate design, which helps distribute the load across two smaller clutch discs. This configuration is key to managing higher torque capacities while keeping the overall size and weight manageable. The R-Trim designation indicates a specific friction material compound chosen for its durability and consistent engagement under demanding conditions. The kit includes a billet steel flywheel, which is lighter and stronger than cast iron, helping to reduce rotational mass for quicker engine response. You'll also find the necessary pilot bearing and alignment tool included, making the installation process smoother. SPEC has engineered this kit to provide a solid engagement feel, giving you confidence when launching or shifting aggressively.

When installing a high-performance clutch like this, it's important to ensure your flywheel is properly resurfaced or replaced, and that all associated components like the clutch fork and release bearing are in good condition. This kit is a significant upgrade for serious enthusiasts looking to maximize their WRX STi's performance potential and ensure their drivetrain can keep up with their power goals.
