Product details

Drivers with a 2011 or 2012 Infiniti Q60 can fit CIN020-C3, and the Circuit Pro 3 Way is the one approved set for that car. Springs are 18 kg/mm in front and 14 kg/mm in back. The dampers arrive valved to the application, and each damper has a knob for its 36 levels of damping.

Mounting runs through the adjustable lower mount, which keeps full travel while the ride height drops, plus pillowball upper mounts that add camber and caster adjustment on MacPherson fronts. Those mounts replace the stock rubber or plastic parts to cut flex. Three independent controls and the external reservoir together produce 11,664 settings. Use the year, make and model checker to confirm the trim, and expect a full alignment once the car is down. The front pillowball mounts are where alignment work starts, because the camber and caster changes are made there.

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.
