What is the advantage of a twin-disc clutch over a single-disc clutch?

A twin-disc clutch has two friction surfaces instead of one. This distributes the torque load across both discs, allowing each to handle less stress. It results in a higher overall torque capacity and improved heat management, making it suitable for high-performance applications.

What does 'pull-type' clutch mean for my Subaru?

A pull-type clutch is the standard mechanism used in your Subaru Impreza and WRX STI from the factory. This kit is designed to replace your original clutch using the same actuation method, which generally simplifies the installation process as it doesn't require modifying the clutch fork or release bearing setup.

What is the recommended break-in procedure for this clutch kit?

Refer to the manufacturer's installation instructions for the specific break-in procedure. Typically, this involves a period of gentle driving, avoiding hard acceleration, slipping the clutch, or towing for the first few hundred miles to allow the friction surfaces to properly mate.

Product Details

Built with a twin-disc ceramic design, this Comp1 Clutch kit is made to handle the demands of high-horsepower Subaru Imprezas from 2004 to 2014, and WRX STi models from 2015 to 2016. The ceramic friction material is known for its ability to withstand significant heat and torque, making it a solid choice for modified vehicles or those that see frequent track use. This setup uses a pull-type clutch mechanism, which is what your Subaru came with from the factory, simplifying the installation process compared to a push-type conversion.

This isn't just a single clutch disc; it's a twin-disc setup. Having two friction surfaces means the load is distributed, allowing each disc to handle less stress. This design contributes to a longer lifespan under aggressive driving conditions and provides a more robust engagement. The kit includes everything needed for the clutch replacement, ensuring you have the right components to get your drivetrain back in working order. Proper installation is key, so refer to the manufacturer's instructions for specific details on torque specifications and break-in procedures.

When you're pushing your Subaru's engine to its limits, having a clutch that can keep up is essential. This Comp1 Clutch kit offers the strength and reliability needed to transfer power effectively, especially if you've upgraded your turbo or engine tuning. It's a significant upgrade over a stock clutch, designed for drivers who need a dependable connection between their engine and transmission under demanding circumstances.
