BC Racing RM Series Coilovers (True Rear) for 2006-2011 BMW 330i RWD (E90)

BC Racing RM Series Coilovers for the 2006-2011 BMW Coupe are purpose-built for McPherson-strut cars that see serious track time, with an inverted mono-tube damper engineered to outlast a hard season of lateral loads. Every kit is extensively tested on the Coupe chassis and refined until it balances ride quality with performance, the reason Coupe coilovers from BC Racing are the best-selling adjustable kits in their segment worldwide.

The RM Series inverts the mono-tube damper on strut-equipped chassis, putting the heavy internals where the lateral loads are worst. A wider piston shaft than conventional uprights means more consistent damping on long sessions and more fatigue life before rebuild. BC Racing takes pride in choosing spring rates and damper valving that balance comfort and performance, you never end up with the oversprung, harsh-riding kit some brands ship as their only option. Drivers who want to deviate from the factory setup can order Swift Springs, spring rates, and valving at checkout; BC will re-valve the dampers to match whatever you specify, a level of ization most brands reserve for their top-tier race kits.

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 ization, proven reliability, and a fully rebuildable damper design that lasts years instead of seasons. These Coupe coilovers arrive tuned for the Coupe chassis and ready to bolt in, no break-in period, no guessing at setup. Every kit ships with a 2-year manufacturer warranty, lifetime access to BC service parts (pistons, seals, shafts, no unit replacement required when it”s time for a rebuild), and in-house tech support from both BC Racing and the Springrates team.
