Product details
The Kontrol Sport coilover for the 2006 to 2010 Infiniti M45 (Y50, rear-wheel drive) is CIN040-SP. Front springs are rated 18.6 kg/mm and rear springs 9.8 kg/mm, and the four units arrive sprung and valved for this car with 36 damping levels per damper.
The valving is 30 percent stiffer than the Kontrol Pro, and the monotube body dissipates heat faster and more evenly while allowing finer adjustment. Pillowball top mounts with camber adjustment sit on the fronts, and the lower mount keeps full travel while ride height is set. The rear uses a true coilover setup. Aluminum mounts, collars and spring perches are 6061-T6 billet. The 2006 to 2010 M35 is also listed, so confirm your body and year with the fit checker. Spring rates and valving are matched for this car, so the set is meant to work as one unit.
Supported features
36 levels of damping adjustment let you dial the system in for handling and comfort. Adjustment alters compression and rebound together for effective, user-friendly setup changes.
Oil and gas stay separated within the cylinder. Compared with twin-tube construction, a monotube dissipates heat faster and more evenly, allows finer damping adjustment, and resists aeration and cavitation for consistent ride quality.
Many MacPherson-strut applications use pillowball top mounts front and rear, installing to OEM specifications. The patented mount adds adjustability, combats noise, and sharpens steering feel and response.
Most applications adjust ride height without losing suspension travel, so you reach the height you want without bottoming out the shock. Separate rear shock-and-spring applications adjust at the spring perch and lower mount.
KSport's advanced upper pillowball mount is available on many applications, giving separate camber and caster adjustment for alignment work and removing the need for a separate camber kit.
Mounts, collars, and spring perches are machined from 6061-T6 billet aluminum for a lightweight, durable, corrosion-resistant build. 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.
