Spec 04-10 BMW 325 2.5L/3.0L E90/E91 Stage 2 Clutch Kit

This SPEC Stage 2 clutch kit, part number SB072-2, is built with a sprung, multi-plate design that handles significantly more torque than the factory setup. This makes it a solid choice for BMW 325 models from 2004 to 2010 with the 2.5L or 3.0L engine, especially if you've made other performance modifications or plan to. The sprung hub helps absorb some of the shock and vibration, contributing to a smoother engagement than you might expect from a higher-performance clutch.

The clutch disc in this kit features a high-performance friction material designed for durability and consistent engagement under increased load. Paired with a robust pressure plate, this kit offers a noticeable improvement in holding power, allowing you to put more power down to the wheels without clutch slip. While it's a step up in performance, the sprung design aims to keep drivability manageable for daily use, though engagement will be firmer than stock. It's important to note that a clutch break-in period is typically recommended for new clutch installations to ensure optimal performance and longevity.

When installing this clutch kit, it's crucial to have the correct tools and to follow the manufacturer's recommended procedures. This kit is designed as a direct replacement for the stock clutch assembly, but it's always a good idea to inspect the flywheel for wear and resurface or replace it if necessary. Ensure you have a new pilot bearing and release bearing, as these are critical wear items that should be replaced whenever the clutch is serviced.
