Product details
On a 2002 to 2004 Subaru Impreza WRX STI, the Kontrol Plus 2-Way is the dual-adjustment option: 36 damping levels at the top plus 24 levels of nitrogen adjustment at the bottom of the external reservoir. According to the page, rebound, compression and nitrogen pressure can be set independently, giving 864 possible settings.
Those settings sit on top of springs rated 9.8 kg/mm in front and 6.1 kg/mm in the rear. KSport describes Kontrol Plus as running 2 to 3 kg stiffer springs and 60 to 150% stiffer damping than Kontrol Pro, so expect a firmer package. The monotube design keeps oil and gas apart for steadier heat dissipation, and the advanced pillowball mounts on MacPherson applications are camber and caster adjustable, replacing stock rubber or plastic parts to reduce flex.
You receive four assembled coilovers, upper mounts, damping knobs and spanner wrenches. The adjustable lower mount sets ride height without limiting shock travel. Lock each collar with both wrenches, start 18 clicks counterclockwise from full stiff and add a professional alignment. The 2002 to 2007 Impreza WRX is also named. Use the year, make and model checker for confirmation.
Supported features
36 levels of damping adjustment at the top of the assembly, plus an additional 24 levels of nitrogen adjustment at the bottom of the reservoir.
Kontrol Plus 2-Way systems run 2–3 kg stiffer spring rates and 60–150% stiffer damping than the Kontrol Pro kit.
Standard external reservoirs allow rebound, compression, and nitrogen pressure to be adjusted independently — 864 possible settings.
Oil and gas stay separated within the cylinder for faster, more even heat dissipation, finer damping adjustment, and resistance to aeration and cavitation.
Standard on MacPherson-strut applications: camber and caster adjustable mounts that replace the stock rubber or plastic mounts to reduce flex and improve response.
Most applications adjust ride height without affecting shock and spring travel, so you can set your stance without bottoming out the shock.

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.
