What is the main advantage of a twin disc clutch setup?

A twin disc clutch uses two smaller clutch discs instead of one large one. This design significantly increases the torque holding capacity while allowing for a more compact assembly that can fit within the transmission bellhousing. It also helps reduce rotational mass for improved engine response.

Does this kit include a flywheel?

This SPEC X-Trim Mini Twin Disc Clutch Kit includes the clutch discs and pressure plates. It is designed to work with your existing E30 chassis flywheel, though it is recommended to inspect and resurface or replace the flywheel if it shows signs of wear.

What kind of driving is this clutch kit best suited for?

This X-Trim Mini Twin Disc clutch kit is built for high horsepower applications and demanding use. It's ideal for modified BMW 325i vehicles that are used for performance driving, track days, or situations where the stock clutch would not be sufficient.

About this part

Product Details

SPEC is known for making well-built clutch components that can handle serious power. This X-Trim Mini Twin Disc Clutch Kit is a prime example, built specifically for the 1987-1993 BMW 325i with the M20 2.5L engine on the E30 chassis. If you're pushing your 325i beyond what a stock clutch can handle, or if you're rebuilding the drivetrain for a high-performance application, this kit is designed to get the power down reliably.

This is a mini twin disc setup, meaning it uses two smaller clutch discs instead of one larger one. This design allows for a significant increase in holding capacity while keeping the overall diameter of the clutch assembly manageable, which is crucial for fitting within the E30's transmission bellhousing. The twin disc configuration also helps to reduce rotational mass compared to a single disc of equivalent holding power, which can lead to improved engine response. The kit includes everything you need to get your clutch system updated, featuring high-performance friction materials and robust pressure plates designed to work together seamlessly.

When installing a high-performance clutch like this, it's always a good idea to inspect your flywheel for any signs of wear or damage. If your flywheel is worn or warped, it's best to have it resurfaced or replaced to ensure proper clutch engagement and longevity. This SPEC clutch kit is a solid option for BMW enthusiasts looking for a clutch that can keep up with their modified vehicle.
