Product details
An IS-F from 2008 to 2013 can run the Asphalt Rally Spec AR coilover, a setup meant for hard use on paved roads with bumps. The four assembled coilovers arrive sprung and valved for this application, with 20 kg/mm springs up front and 12 kg/mm in the rear.
The AR design centers on an extended shock stroke and, on MacPherson applications, an inverted steel shock that moves the gas and oil away from the brakes and knuckle. Damping offers 36 levels of adjustment, and the 55 mm shock bodies add oil capacity and cooling under sustained loads.
Strengthened steel lower mounts are standard on MacPherson applications, so the lower mounting points are built for regular hard use. Set ride height at the adjustable lower mount, lock every collar with both spanner wrenches, and begin damping from full stiff, backing off 18 clicks. Check fit against the year, make and model checker. The GS300, GS430 and GS450 are also listed for this system.
Supported features
Gravel Rally springs range from 250 mm to 270 mm with extended cylinder length and piston stroke, greatly improving handling over uneven and bumpy roads. Height range varies per vehicle and does not exceed OE ride height.
Asphalt Rally uses inverted shocks on many MacPherson applications, moving the gas/oil chamber away from the knuckle and brakes to reduce heat transfer and unsprung weight.
Strengthened steel lower mounts are standard on MacPherson applications; Gravel Rally adds heavy-duty steel upper mounts on most applications. Wishbone and multi-link applications use the standard aluminum mounts.
Gravel Rally kits use unique hardened-rubber pillowball top mounts on MacPherson applications to absorb repeated impacts from loose surfaces.
Simultaneous compression and rebound adjustment across 36 levels, with carefully selected per-application spring rates and damping to stabilize the car over uneven roads.
Inverted applications use 55 mm bodies for added oil capacity and cooling under sustained stage loads.

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.
