BC RACING COILOVERS HM SERIES - BMW 3 SERIES E46 CONVERTIBLE (98-06) model-M140i (F20 This helps prevent fade duringThe BC Racing HM Series builds on the capabilities of the RM range but adds fully independent 2 way damping adjustment for serious track use. Each HM kit features inverted monotube dampers with separate compression and rebound control, giving drivers the ability to fine tune handling balance with far greater precision. The inverted damper design relocates critical damper fluid and internal components away from heat sources such as brakes and hubs.
