Product details
The Circuit Pro 3-Way coilovers are approved for the 2008 to 2014 Subaru Impreza WRX on the GH8 chassis as a sedan or hatchback, with 16 kg/mm springs at both ends. Three-way independent adjustment provides 11,664 combinations. Check the fitment against the year, make and model checker before ordering.
Reservoirs are external and standard, so rebound, compression and nitrogen pressure can be set independently, and some vehicles take front reservoirs only where rear space is limited. Shock stroke runs 20 to 30 mm shorter than street kits, and you may choose proven spring rates or supply your own custom rates.
Full soft is the comfortable end of the 36 damping levels, and firmer settings suit track work. Camber and caster are adjustable at the top mounts on MacPherson-strut cars, which replace the stock rubber or plastic parts and reduce flex.
Supported features
36 levels of damping adjustment. Set damping to full soft for a comfortable cruising setting for normal driving.
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.
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.
Standard on MacPherson-strut applications: camber and caster adjustable mounts that replace the stock rubber or plastic mounts to reduce flex.
Oil and gas stay separated within the cylinder for faster, more even heat dissipation, finer damping adjustment, and consistent ride quality.
Mounts, collars, and spring perches are machined from 6061-T6 billet aluminum; steel shock bodies are zinc-plated for added protection from corrosion.
Compatible applications (2)
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.
