Product details

The Circuit Pro 3-Way coilover is built for the 1989-1991 Honda CR-X EF, part CHD010-C3. Springs are rated 18 kg/mm front and 16 kg/mm rear, and the shock stroke runs 20-30 mm shorter than street kits. Four assembled coilovers arrive sprung and valved for this application, with aggressive spring rates and valving.

The 3-way independent adjustment gives 11,664 combinations across rebound, compression and nitrogen pressure on the external reservoir. Damping has 36 levels on one knob per damper. Reservoirs are standard, although some applications get front reservoirs only, where rear space is limited.

Custom spring rates are an option, because the shocks are valved to the rates you select. Advanced pillowball top mounts with camber and caster adjustment are standard on MacPherson-strut applications. The Integra from 1990 to 1993 and the Civic from 1989 to 1991 are also listed, so confirm fitment with the year/make/model checker.

Supported features
36-Way Adjustable Damping

36 levels of damping adjustment. Set damping to full soft for a comfortable cruising setting for normal driving.

External Reservoirs

Standard external reservoirs allow rebound, compression, and nitrogen pressure to be adjusted independently — 11,664 possible combinations. Some vehicles receive front reservoirs only where rear space is limited.

Built for Racing

Aggressive spring rates and shock valving combined with a 20–30 mm shorter shock stroke. Choose proven spring rates or your own custom rates; the shocks are valved to what you select.

Advanced Pillowball Top Mount

Standard on MacPherson-strut applications: camber and caster adjustable mounts that replace the stock rubber or plastic mounts to reduce flex.

Monotube High-Pressure Design

Oil and gas stay separated within the cylinder for faster, more even heat dissipation, finer damping adjustment, and consistent ride quality.

Aerospace-Grade Aluminum

Mounts, collars, and spring perches are machined from 6061-T6 billet aluminum; steel shock bodies are zinc-plated for added protection from corrosion.

Installation

Set ride height with the adjustable lower mount where the application has one; use the spring perch only where the application-specific layout has no adjustable lower mount. Lock every collar with both spanner wrenches. Start damping 18 clicks counterclockwise from full stiff and adjust from there. Professional setup and alignment are required after installation; on MacPherson fronts, establish baseline camber at the elongated lower-mount hole before fine adjustment at the upper plate.
