Spec 83-84 BMW 533 / 85-88 535 / 78-84 633 / 85-89 635 / 84 733 / 85-87 735 Aluminum Flywheel

This SPEC aluminum flywheel (part number SB80A) is what you get when you're looking to shed some weight from your BMW's drivetrain. It's designed to replace the heavier factory flywheel found in a range of BMW models, including the 1983-1984 533i, 1985-1988 535i, 1978-1984 633CSi, 1985-1989 635CSi, the 1984 733i, and the 1985-1987 735i. By reducing the rotational mass at the crankshaft, this flywheel helps your engine rev up more quickly, giving you a more responsive feel when you accelerate.

Crafted from a solid piece of aluminum, this flywheel is significantly lighter than its stock counterpart. This weight reduction isn't just about numbers; it directly translates to improved acceleration and a livelier engine response. While it's a lighter part, SPEC builds these to handle the demands of daily driving and spirited use. It's a well-built component that aims to give your BMW's engine a bit more eagerness. When installing, remember that a lighter flywheel can make the engine slightly less forgiving at very low RPMs, but for most drivers, the improved performance is a worthwhile trade-off.

This flywheel is designed as a direct replacement for the original part, meaning it should bolt up to your existing clutch components and transmission without needing extensive modifications. Ensure you have the correct clutch disc and pressure plate designed for this specific flywheel to get the best performance and longevity out of your new setup. It's a solid option if you're looking to enhance your BMW's performance feel.
