Product Details

These BC Racing ER Series coilovers fit the 2012-2020 Seat Leon FWD (54.5mm Strut). 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 Seat Leon 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. 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 BC Racing Seat Leon 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.
