Tilton Twin Disc Clutch Kit – BMW E46 M3 – Organic Disc / 8.5” Flywheel / ARP Hardware
The Tilton ST-215 Twin Disc Clutch Kit is engineered from the ground up for serious street and street/strip performance. Unlike modified OEM clutches that rely on stamped steel components and add-on floaters, the ST-215 is a purpose-built, high-performance clutch system rooted in Tilton’s motorsport pedigree.
Featuring a lightweight billet aluminum clutch cover adapted from Tilton’s OT-Series racing clutches, the ST-215 offers superior heat management, strength, and noise control. Heavy-duty straps securely connect the pressure and floater plates to reduce unwanted chatter—ideal for high-output engines in daily driven or weekend track cars.
The included Tilton Engineering steel flywheel is a purpose-engineered solution that balances performance and drivability. With a larger diameter than the OEM flywheel, this unit delivers increased rotational inertia for smoother power delivery and more predictable clutch engagement.
Key Features:
- Purpose-built twin disc clutch for high-performance use
- Available with organic friction discs
- Lightweight aluminum clutch cover with racing tech
- Heavy-duty straps for reduced noise and improved durability
