Product Details
These BC Racing ER Series coilovers (True Rear) fit the 1984-1987 Toyota Corolla (AE86) w/ Front Spindle. They put race-grade adjustability in reach of the serious track-day driver, with independent compression and rebound tuning at every corner. Every kit is developed specifically for the Toyota AE86 Corolla and refined to balance ride quality with performance, which is why BC coilovers 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, custom rates, and custom valving are all options at checkout, BC will match the valving of the dampers to whatever springs you pick, something most brands don't offer outside their flagship race lineup.
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 customization options, and a damper design any suspension shop can rebuild instead of replacing. These BC Racing AE86 Corolla coilovers arrive ready to bolt in, with no break-in period and 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.
