What is a Stage 5 clutch and who is it for?

A Stage 5 clutch, like this SPEC kit, is designed for vehicles with significantly increased horsepower and torque, often from engine modifications. It's intended for drivers who engage in aggressive driving, track use, or regularly tow heavy loads, where a stock clutch would fail.

What components are typically included in this clutch kit?

This SPEC Stage 5 clutch kit includes a high-performance pressure plate and a sprung, multi-plate clutch disc. These components are specifically engineered to work together to handle extreme power levels.

Are there any other parts I should consider replacing when installing this clutch?

It's a good practice to replace wear items like the pilot bearing and rear main seal while the transmission is removed for clutch installation. Inspecting the flywheel for damage and resurfacing or replacing it is also recommended for optimal clutch performance.

About this part

Product Details

If you're pushing your 1979-1982 Mazda RX-7 well beyond stock power levels, you need a clutch that can keep up. This SPEC Stage 5 clutch kit is designed for those high-horsepower builds and aggressive driving styles where a standard clutch just won't cut it. It's engineered to handle the demands of serious performance modifications, ensuring your power gets to the ground reliably.

This Stage 5 kit features a sprung, multi-plate design, which is crucial for managing extreme torque and heat. The sprung hub helps absorb shock, making it more manageable for daily driving than some other high-performance options, while the multi-plate setup significantly increases the surface area for engagement. This means more clamping force and better heat dissipation, preventing premature wear and slippage under heavy load. The kit includes a high-performance pressure plate and a clutch disc specifically matched to handle the increased demands of a modified rotary engine.

When installing a clutch kit of this caliber, it's important to ensure all mating surfaces are clean and properly prepped. You'll also want to consider replacing your pilot bearing and rear main seal while the transmission is out, as these are common maintenance items that are easily addressed during a clutch job. This SPEC clutch is a solid option for RX-7 owners looking to maximize their drivetrain's capability.
