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

A Stage 4 clutch kit is designed to handle significantly increased horsepower and torque compared to a stock clutch. It uses advanced friction materials like carbon-ceramic to manage the higher heat and stress generated by modified engines, preventing slippage and ensuring reliable power transfer.

Does this clutch kit include a new flywheel?

This SPEC Stage 4 clutch kit includes the clutch disc and pressure plate assembly. It does not typically include a new flywheel, so it is recommended to inspect your existing flywheel for wear and consider resurfacing or replacing it during installation.

How does the sprung hub affect the clutch feel?

The sprung hub in the clutch disc helps to dampen vibrations and shock loads that are transmitted through the drivetrain. This can make the clutch engagement feel a bit smoother and more comfortable for daily driving compared to an unsprung hub, especially with a high-performance clutch.

About this part

Product Details

If you're looking to handle significantly more power in your classic BMW, like a 1974 Bavaria or a 1979 528i, a Stage 4 clutch kit is a serious upgrade. This SPEC Stage 4 kit is built for those who have modified their engine to make substantially more horsepower and torque than stock. It's designed to hold up under demanding conditions where a standard clutch would quickly start to slip.

This particular kit features a sprung hub clutch disc, which helps absorb some of the shock and vibration that comes with a high-performance clutch, making it a bit more manageable for daily driving or spirited canyon runs. The disc itself is a carbon-ceramic material, known for its ability to handle extreme heat and high torque loads without fading. This means you get consistent engagement and reliable power transfer even when you're pushing your BMW hard. The kit includes the necessary components to replace your old clutch assembly, ensuring a proper fit for models like the 1975 3.0Si or the 1983 533i.

When installing a clutch of this caliber, it's important to ensure your flywheel is in good condition, or consider resurfacing or replacing it. This kit is a robust solution for drivers who have invested heavily in engine performance and need a clutch that can keep up. It's a well-built component designed to transfer significant power reliably.
