Lightweight single mass flywheel for BMW E82 and E90 models with N54 or N55 engines - no guesswork, no fluff. Choose billet aluminium (14 lb, SB53A-2/SB53A-3) for fast road or track day use, or billet steel (22 lb, SB53S-2/SB53S-3) for sharper throttle response while keeping daily drivability intact.
Direct fit: Bolt-on replacement for stock dual mass units - no machining or adaptation needed
Measurable gains: +10-17 whp depending on material, with faster spool and crisper rev response
Rebuildable design: Replace friction surfaces or reface as needed - built to last, not discard
Clutch-ready: Fully compatible with SPEC BMW clutch kits for matched performance
