Spec 86-93 BMW 325i Stage 5 Clutch Kit

This is the SPEC Stage 5 Clutch Kit, part number SB105, designed for high-performance applications in vehicles like the 1987-1991 BMW 325i, 1984-1986 BMW 325e, and 1982-1986 BMW 528e. If you're pushing your BMW's engine to its limits and need a clutch that can handle serious power, this kit is built for the job. It's engineered to manage significantly increased torque and horsepower, making it a popular choice for track use or heavily modified street cars that demand more from their drivetrain.

The Stage 5 kit features a sprung hub performance disc, which helps absorb some of the shock and vibration associated with aggressive engagement, while still providing a solid connection. This is paired with a heavy-duty pressure plate that offers a much firmer clamping force than stock. This increased clamping force is crucial for preventing clutch slippage under high load, ensuring all the power from your engine gets to the wheels. The sprung hub design also helps to protect your transmission's input shaft from excessive shock loads, which can be a concern with stiffer clutch setups.

When installing a high-performance clutch like this, it's important to be aware that engagement can be more abrupt than a stock clutch. This is normal for a clutch designed to handle this level of power. You'll want to ensure your flywheel is in good condition, and consider resurfacing or replacing it if necessary. This kit is a solid option for BMW owners looking to significantly upgrade their clutch's capability for demanding driving scenarios.
