Product details
Circuit Pro 3-Way is the track-leaning coilover for a 2006 to 2013 Lexus IS350 (rear-wheel drive), supplied as four assembled coilovers. Springs are rated 24.8 kg/mm up front and 20 kg/mm in the rear, and the kit is sprung and valved for this application.
Three-way adjustment is the main draw. Damping has 36 levels per damper, and external reservoirs (standard, front only on some applications) let rebound, compression and nitrogen pressure be set independently for 11,664 combinations. The adjustable lower mount keeps full shock travel while the car is lowered. The stroke is 20 to 30 mm shorter than a street kit, which firms up control.
Use the adjustable lower mount to set height, lock each collar with both spanner wrenches, and start damping 18 clicks counterclockwise from full stiff. Pillowball upper mounts with camber adjustment help when setting alignment, and the mounts and collars are 6061-T6 billet aluminum. Confirm fit with the year, make and model checker; the GS430, GS300 and IS250 are also listed for this system.
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.
