Product details
Version RR is the road race coilover for the 2006 to 2013 Lexus IS250 RWD, built around four assembled coilovers with aggressive spring rates and valving. The springs are 24.8 kg/mm at the front and 20 kg/mm at the rear, and the shock stroke is 20 to 30 mm shorter than on the street kits.
Race-focused parts show up throughout the set. Upgraded bumpstops keep the shock from bottoming out over uneven pavement, and 36 levels of damping adjustment let you move from a soft cruising setting to a firm one for the track. Mounts, collars and spring perches are machined from 6061-T6 billet aluminum, and custom rates are available if the standard springs are not what you want.
The same coilover is also listed for the 2008 to 2013 Lexus IS-F, the 2006 to 2012 GS430, GS450, GS350 and GS300, and the 2006 to 2013 IS350 RWD. Confirm the IS250 fit with the year, make and model checker before ordering, and lock every collar with both spanner wrenches once the height is set.
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.
