Product details
If you chase lap times in a 2009 to 2018 Nissan 370Z, the Circuit Pro 3-Way is the coilover with every dial. Standard external reservoirs allow rebound, compression and nitrogen pressure to be tuned independently, giving 11,664 combinations, although some vehicles get front reservoirs only where rear space is limited.
Springs are 18 kg/mm in front and 14 kg/mm in the rear, and the shock stroke is 20 to 30 mm shorter than street kits. Choose the proven rates or your own, and the dampers will be valved for your selection. A true rear coilover layout is noted for this car. Each damper also carries 36 damping levels from one knob, with full soft offered as a comfortable cruising position.
Up front, an advanced pillowball mount adjusts camber and caster, replacing stock rubber or plastic parts to cut flex. Inside, a monotube design separates oil from gas for even heat dissipation. The kit contains four assembled coilovers, upper mounts, knobs and spanner wrenches. Because the lower mount adjusts, you can lower the car without losing travel. Infiniti G37, G25, Q40 and Q60 years also appear, so verify fitment with the year, make and model checker.
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.

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.
