Product Details
BC Racing ZX Series Coilovers for the 1997-2004 Chevrolet Corvette (C5) bring the same three-axis adjustability as the race-spec ZR Series with valving tuned for drivers who split time between street and track. Every kit is extensively tested on the C5 chassis and refined until it balances ride quality with performance — the reason Corvette coilovers from BC Racing are the best-selling adjustable kits in their segment worldwide.
ZX Series kits share the three-axis damper architecture of the race-spec ZR Series, tuned out of the box for drivers who want race-grade adjustability without the ride harshness on the commute home. 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.
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 Corvette coilovers arrive tuned for the C5 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.
