Product details
The Version RR Road Race coilover fits the 1998 to 2005 Lexus GS400 (JZS161) and is built for fast corners and hard braking. Four assembled coilovers come sprung and valved for this application, with 24.8 kg/mm springs in front and 20 kg/mm in the rear. Those firm rates and a shock stroke 20 to 30 mm shorter than street kits make this a stiffer setup than most.
Damping uses 36 levels per damper, so you can settle on a comfortable cruise at the soft end and firm up for track sessions. Upgraded bumpstops are fitted to help keep the shock from bottoming out over bumps and harsh pavement. You can run proven spring rates or enter your own custom rates, and the shocks are valved to whichever you choose.
Set ride height on the adjustable lower mount, start damping 18 clicks counterclockwise from full stiff, and tighten each collar with both spanner wrenches. Professional alignment belongs in the install plan. Check fitment with the year, make and model checker before ordering. Also listed for the GS430 and GS300.
Supported features
36 levels of damping adjustment. Set full soft for a comfortable cruising setting for normal driving.
Version RR kits include upgraded bumpstops to prevent the shock from bottoming out over uneven pavement or harsh road conditions.
Aggressive spring rates and valving 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.
Many MacPherson applications have pillowball upper mounts; the patented bearing design combats noise and improves steering feel and response.
Oil and gas stay separated within the cylinder for faster 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.
