What is the main advantage of a twin plate clutch over a single plate clutch?

A twin plate clutch uses two friction discs, which significantly increases the total friction surface area. This allows it to handle much higher torque loads without slipping, making it suitable for heavily modified engines and demanding applications.

Is this clutch suitable for daily driving in my Mazda RX-7?

The OS Giken TS Series clutch features a sprung center hub designed to absorb shock and vibration, which helps improve streetability compared to some other twin plate setups. However, twin plate clutches are generally intended for high-performance use and may have a firmer pedal feel and engagement than a stock clutch.

What else might I need to install this clutch?

When installing a performance clutch, it's recommended to inspect or replace your flywheel, as well as ensure proper alignment. You may also want to consider upgrading other drivetrain components to complement the increased torque capacity of this clutch.

Product Details

This is the OS Giken TS Series twin plate clutch, specifically designed for the 1979-1985 Mazda RX-7 with the 12A engine. If you're building a high-performance RX-7 and need a clutch that can handle serious power, this is the unit you'll want to consider. It's a twin-plate setup, meaning it uses two friction discs instead of the typical single disc found in most street cars. This design significantly increases the surface area for engagement, allowing it to transfer much more torque without slipping.

OS Giken is well-known for making robust drivetrain components, and this clutch is no exception. The TS Series uses a unique sprung center hub design that helps absorb some of the shock and vibration that can come with a twin-plate clutch, making it a bit more streetable than some other high-performance options. The clutch cover is forged for strength, and the pressure plate is designed to provide consistent clamping force. This setup is ideal for rotary engines that are heavily modified for racing or extreme street use, where a stock clutch simply won't hold.

When installing a twin-plate clutch like this, it's important to have a solid understanding of clutch system mechanics. You'll want to ensure your flywheel is properly resurfaced or replaced, and that all alignment is perfect. Because this is a high-performance component, it's often paired with other upgraded drivetrain parts to handle the increased power transfer. This clutch is built to last under demanding conditions, offering a solid solution for RX-7 owners pushing the limits of their 12A engine.
