Product details
The Lexus IS-F Circuit Pro 3-Way coilovers use stout springs, 24.8 kg/mm in front and 20 kg/mm at the rear. Those numbers, plus a shock stroke 20–30 mm shorter than street kits, make this a track-leaning choice for 2008 to 2013 cars. Standard external reservoirs provide independent rebound, compression and nitrogen adjustment, giving 11,664 possible combinations, with front reservoirs only where rear space is limited.
Mounts and perches are machined from 6061-T6 billet aluminum, with zinc-plated steel bodies. Each strut has an adjustable lower mount that preserves travel, and a monotube high-pressure design keeps the damping consistent. You receive four assembled coilovers, upper mounts, knobs and spanner wrenches. Compatible applications also include the IS350 and IS250 (2006 to 2013, RWD) and the GS300, GS350, GS430 and GS450 (2006 to 2012). Verify fitment with the year/make/model checker, and plan for an alignment.
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 (7)
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.
