BC Racing coilover kit for the 1989-1994 Mitsubishi Eclipse (FWD). It comes in 3 series (BR Series, DS Series, RM Series), so you can pick the setup that suits how you drive. Every BC kit is a complete, fully rebuildable coilover system with ride height that adjusts independently of spring compression.
Specifications
- Default spring rates: Standard: front 12 kg/mm - rear 8 kg/mm
- Custom spring rates available on request
BR Series - from $1,774
The BR Series is BC Racing's most affordable full coilover system, and it doesn't cut corners on ride comfort, handling, build quality or ride height. BC Racing tests every vehicle and keeps refining the setup until it is properly balanced, and the off-the-shelf spring rates are picked to sit between comfort and performance, so the car isn't left oversprung. Damping is adjustable over 30 clicks, with compression and rebound set together, which is one of the widest adjustment ranges on the market.
- Highly customizable
- Mono-tube shock design
- Linear piston and damping curve
- Ride height adjusts independently of spring compression
- 30-click damping adjustment (compression and rebound adjusted together)
- Front camber plates standard on applicable kits
- Rear camber plates available on applicable kits
- Custom spring rates and Swift springs available
- Custom valving, or valving matched to custom spring rates
- Fully rebuildable
DS Series - from $2,066
The DS Series uses BC Racing's proprietary digressive piston. It gives more damping force at low piston speeds while keeping a linear feel at higher speeds. That extra low-speed control is what the driver feels most: less roll, pitch and dive, and quicker weight transfer on a technical road course. BC Racing pitches it as the choice for the best driver feel.

- Mono-tube shock design
- Digressive piston and damping curve
- Satin chrome finished shock body

- 30-click damping adjustment (compression and rebound adjusted together)
- Front camber plates standard on applicable kits
- Rear camber plates available on applicable kits
- Custom spring rates; Swift spring compatible
- Custom valving, or valving matched to custom spring rates
- Fully rebuildable
RM Series - from $2,212
The RM Series uses inverted mono-tube dampers front and rear on cars with McPherson strut suspension from the factory. On cars with front struts only, you get an inverted front strut and an upright BR Series damper at the rear. Inverting the strut puts most of its mass up top, on the sprung side of the chassis, which cuts unsprung weight. The RM's much larger inverted piston shaft handles high lateral loads for longer without fatigue. Those loads only really occur on McPherson struts, not on double A-arm cars.

Top plate types
- RA Type: front pillowball or camber top mount, rear rubber or reuse OEM top mount
- RH Type: front pillowball or camber top mount, rear pillowball or camber top mount
- DA Type: front pillowball or camber top mount, rear rubber or reuse OEM top mount
- DH Type: front pillowball or camber top mount, rear pillowball or camber top mount
- MA Type: front pillowball or camber top mount, rear rubber or reuse OEM top mount
ER, HM, ZR and ZX Series kits come with pillowball or camber upper mounts where the car allows it. Camber plates are only included on kits where they apply. Pillowball mounts are rigid motorsport parts: they sharpen handling but add a lot more noise, vibration and harshness than OEM or rubber mounts.
