Product Details
BC Racing HM Series Coilovers for the 1996-1999 BMW 328i True Rear Coilover 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 328i True Rear Coilover chassis and refined until it balances ride quality with performance, the reason 328i True Rear Coilover 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. The off-the-shelf setup from BC Racing is deliberately balanced, spring rates and valving chosen so the kit feels comfortable day-to-day without giving up performance when you push it. Drivers who want a different recipe can spec Swift Springs, custom spring rates, or fully custom valving at checkout; BC will tune the dampers to match, which is a depth of customization most brands only offer on their top-tier kits.
BC Racing's reputation in the aftermarket suspension world is built on four things: competitive pricing that beats the rest of the fully-adjustable market, customization depth that rivals the top-tier race brands, long-term reliability earned over 20 years of production, and a rebuildable design that keeps the same set of dampers serving you through multiple builds. These 328i True Rear Coilover coilovers arrive tuned for the 328i True Rear Coilover 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.
