BC Racing ER Series Coilovers (True Rear) for 2001-2006 BMW M3 Coupe RWD (E46)

Product Details

BC Racing ER Series Coilovers for the 2001-2006 BMW M3 Coupe put race-grade adjustability within reach of the serious track-day driver, with independent compression and rebound control at every corner so you can separate low-speed body control from high-speed compliance.

Compression and rebound are adjusted on separate circuits, so you can dial in body control and compliance independently rather than trading one for the other. Ride height remains adjustable independent of spring preload, and custom rates or valving can be specified at checkout.

BC Racing has been manufacturing adjustable coilovers since 2004 and is one of the most popular coilover brands in the automotive tuning industry for a reason: competitive pricing, deep customization, proven reliability, and a fully rebuildable damper design. Every kit ships with a 2-year manufacturer warranty, lifetime access to BC service parts, and in-house tech support from both BC Racing and the Springrates team.
