Product Details
BC Racing RM Series Coilovers for the 2001-2006 BMW M3 Coupe are built around an inverted mono-tube damper, putting the larger-diameter body at the top of the strut for greater bending stiffness under load. It is the choice for cars that see serious track time.
The inverted design reduces stiction and improves damper stability under high cornering loads. Ride height stays adjustable independent of spring preload, and Swift Springs or custom 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.
