The VA-generation Impreza WRX and WRX STI put a torquey boxer engine through a symmetrical all-wheel-drive system, and that layout changes how the car loads its suspension compared with a front-drive hatch: power goes down through all four corners under acceleration, and the chassis has to manage that transfer as much as it manages cornering load. Standard dampers on a car this age are worn well past their design window, and the factory spring rates were never chosen with track days in mind.
XYZ Racing’s Super Sport coilover is built for exactly that gap – fast-road driving with regular weekend track sessions, not a full-house race build. It replaces the factory strut and spring assembly front and rear with a height-adjustable, damping-adjustable unit designed to keep the WRX/STI’s all-wheel-drive platform composed without turning the daily commute into a chore.
What this coilover does for your 2015-2021 Subaru IMPREZA WRX/ WRX STI AWD 4WD
With 36-way damping adjustment, you can wind the compression and rebound down for a comfortable daily setting or firm it up for a track session without swapping parts. That range matters on a symmetrical AWD car like the WRX/STI, where body control on turn-in has to be balanced against the traction the all-wheel-drive system is putting down out of the corner – too soft and the nose wallows under the boxer engine’s torque, too stiff and you lose the mechanical grip the AWD layout is there to exploit. Ride height adjustment lets you correct the stance and corner-weight the car after fitting, which matters on a chassis that’s often lowered incorrectly on cheaper kits and ends up with mismatched suspension geometry. The result on your Impreza WRX or STI is a car that turns in with less initial roll, holds a line through faster corners with the AWD system doing its job properly, and still rides acceptably on a motorway run home from the track.
About the Super Sport coilover
The Super Sport line is built to take the harshness out of rough UK B-roads and pockmarked motorways without giving up the control a fast-road or track-day driver wants. Its 36-way damping adjustment covers a genuinely wide range, from a compliant road setting through to a firmer track calibration, so one kit does both jobs rather than forcing a compromise. Ride height is independently adjustable at each corner, which lets you set stance and geometry properly rather than just winding the car down. Construction follows XYZ Racing’s usual damper architecture, built to hold that adjustment range consistently rather than fading after a handful of track outings. It’s positioned as the kit for owners who want their WRX or STI sharper on a Sunday morning drive and usable on a track day, without stepping up to a fully stripped-out competition setup.
Fitment for the Subaru IMPREZA WRX/ WRX STI AWD 4WD (2015-2021)
This kit is built for the SU12-chassis Impreza WRX and WRX STI, AWD models produced across the 2015 to 2021 model years. It covers both the WRX and STI variants of this generation, matched to the AWD platform’s front and rear mounting points and geometry. Confirm your build year and trim against this range before ordering, as suspension geometry changed between chassis generations.
