BC Racing ER Series Coilovers for 2001-2003 Acura CL FWD (YA4)

BC Racing ER Series Coilovers for the 2001-2003 Acura CL (YA4) put race-grade adjustability in reach of the serious track-day driver, with independent compression and rebound tuning at every corner. Every kit is extensively tested on the YA4 chassis and refined until it balances ride quality with performance, the reason CL coilovers from BC Racing are the best-selling adjustable kits in their segment worldwide.

ER Series kits run a linear twin-piston design in a mono-tube body, with compression and rebound on separate external adjusters. That lets you fine-tune chassis balance corner by corner, stiffer front for turn-in, softer rear for exit grip, whatever the session calls for. Where BC Racing separates itself is tuning philosophy: every off-the-shelf spring rate and damper setup is chosen to stay comfortable on daily roads while still delivering real performance at the track. If you want something different, Swift Springs, rates, and valving are all options at checkout, BC will dyno-match the dampers to whatever springs you pick, something most brands don”t offer outside their flagship race lineup.

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, ization 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 CL coilovers arrive tuned for the YA4 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.
