BC Racing ER Series Coilovers for 2003-2008 Nissan 350Z (Z33)

BC Racing ER Series Coilovers for the 2003-2008 Nissan 350Z (Z33) 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 350Z Z33 chassis and refined until it balances ride quality with performance, the reason 350Z 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. 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, spring rates, or fully valving at checkout; BC will tune the dampers to match, which is a depth of ization 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, 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 350Z coilovers arrive tuned for the Z33 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.
