Specifications — CIN020-AR
Product details
The 2014 and 2015 Infiniti Q40 sedan with rear-wheel drive is the approved application for CIN020-AR. Four assembled coilovers are sprung and valved for it, with 14 kg/mm springs at the front, 8.7 kg/mm at the rear, and a separate damping knob on each unit with 36 levels of adjustment.
Asphalt Rally uses an extended shock stroke, an inverted shock on MacPherson fronts, and a 55 mm body for added oil capacity and cooling. Pillowball upper mounts with camber adjustment sit on those fronts, and the adjustable lower mount keeps shock travel intact as the ride height comes down. The kit is also listed for the G37 (coupe and sedan RWD), the G35 sedan and the 2014 to 2015 Q60 coupe. The coilovers are rebuildable, and replacement shocks, springs, mounts and hardware are sold individually. Check the year, make and model checker to be sure the sedan matches yours.
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.
