What is the primary benefit of a Stage 4 clutch kit?

A Stage 4 clutch kit is built to handle significantly more torque and horsepower than a stock clutch. This makes it ideal for vehicles with engine modifications or for those who frequently engage in track driving or other demanding performance applications.

What specific parts are included in this SPEC Stage 4 clutch kit?

This kit includes a high-performance clutch disc and a release bearing. Please note that it requires a separate E36 M3 pressure plate, which is not included in this package.

What does 'Alt Spline' mean in the product description?

Alt Spline refers to an alternative spline count on the clutch disc. This means it is designed to mate with a specific transmission input shaft or flywheel that differs from the standard configuration for these models.

Product Details

This is a SPEC Stage 4 clutch kit, designed for the 2001-2006 BMW M3 with the 3.2L engine and the 2006-2008 BMW Z4 with the 3.2L engine. A Stage 4 clutch is built for high-horsepower applications, offering a significant increase in holding capacity over stock. This kit is a solid option if you've modified your engine for more power or plan to track your car regularly. It's important to note that this kit requires the use of an E36 M3 pressure plate and features an alternative spline count, so be sure to have the correct components ready for installation.

The Stage 4 clutch kit includes a high-performance clutch disc and a release bearing. The disc is engineered for aggressive engagement and maximum torque transfer, making it suitable for demanding driving conditions. While it offers superior holding power, expect a firmer pedal feel compared to a stock clutch. This is typical for higher-stage clutch kits as they are designed to handle more power without slipping. The alternative spline count is a specific design choice to mate with certain flywheel or transmission setups, ensuring a secure connection.

When installing this clutch kit, it's crucial to follow the manufacturer's instructions carefully, especially regarding the E36 M3 pressure plate requirement and the alternative spline engagement. Proper installation ensures the clutch performs as intended and lasts as long as possible. Given the nature of a Stage 4 clutch, it's often paired with other drivetrain upgrades to fully support the increased power handling capabilities.
