BC Racing DS Series Coilovers for the 1989-1994 Mitsubishi Eclipse (D27A) blend street-tuned ride quality with track-ready adjustability, giving you more body control than any OEM damper without the harshness of a pure race kit. Every kit is extensively tested on the Eclipse D27A chassis and refined until it balances ride quality with performance, the reason Eclipse coilovers from BC Racing are the best-selling adjustable kits in their segment worldwide.
DS Series kits pair a mono-tube damper with BC”s proprietary digressive piston design, increased low-speed damping for flat corner entry, compliant high-speed response over expansion joints and potholes. The finished shock body is silver, visually distinct from the BR Series, and ride height is adjustable independent of spring preload. BC Racing takes pride in choosing spring rates and damper valving that balance comfort and performance, you never end up with the oversprung, harsh-riding kit some brands ship as their only option. Drivers who want to deviate from the factory setup can order Swift Springs, spring rates, and valving at checkout; BC will re-valve the dampers to match whatever you specify, a level of ization most brands reserve for their top-tier race kits.
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 ization options, and a damper design any suspension shop can rebuild instead of replacing. These Eclipse coilovers arrive tuned for the D27A 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.
