BC Racing HM Series Coilovers for the 2001-2005 Honda Civic (EM2/ES1) combine the inverted-damper durability of the RM Series with the independent compression and rebound tuning of the ER Series, BC”s pick for track-day McPherson-strut builds. Every kit is extensively tested on the Civic chassis and refined until it balances ride quality with performance, the reason Civic coilovers from BC Racing are the best-selling adjustable kits in their segment worldwide.
HM Series kits use an inverted mono-tube damper on McPherson-strut chassis (upright on double-wishbone) with external reservoirs feeding separate compression and rebound adjusters. The result: the tuning depth of the ER Series inside the heavy-load chassis architecture of the RM. 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.
Since 2004, BC Racing has grown into one of the most trusted names in aftermarket coilovers, not by racing to the bottom on price, but by pairing that price with real build quality, deep ization options, and a damper design any suspension shop can rebuild instead of replacing. These Civic coilovers arrive tuned for the Civic 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.
