XYZ Racing Racing Spec Coilovers — Subaru IMPREZA WRX/ WRX STI AWD 4WD 2015-2021

The WRX and WRX STI’s symmetrical all-wheel-drive layout shifts torque across the centre differential as you load the car mid-corner, and that transfer is exactly where a soft factory damper runs out of ideas. Trail-brake into a fast corner on the standard setup and the front end dives, the rear squats under power, and the chassis never quite settles before you’re back on the throttle. The Racing Spec coilover is built for owners running this AWD chassis in serious track and time-attack sessions, where that settling time is the difference between a clean apex and a wide one.

This isn’t a firmer version of a road kit. It’s a circuit-first platform, built around damping behaviour XYZ Racing has pulled directly from race weekends rather than a lab bench, then applied to the WRX/STI’s strut-type front end and multi-link rear.

What this coilover does for your 2015-2021 Subaru Impreza WRX/ WRX STI AWD 4WD

Fitted to this chassis, the Racing Spec kit controls the nose-dive under hard braking that the factory struts can’t resist, so trail-braking into a corner stays predictable instead of vague. It sharpens the car’s response to the centre differential’s torque split, keeping the contact patch consistent as power shifts front to rear mid-corner rather than letting body roll mask what the diff is doing. Full ride height adjustment lets you set the WRX or STI’s stance and corner weights specifically for a circuit setup, rather than living with the compromise height Subaru chose for road use. The result is a chassis that changes direction with less lag between input and response, which on an AWD platform this heavy is where most of the lap time is actually found.

About the Racing Spec coilover

XYZ Racing built the Racing Spec damper specifically for circuit racing, and the valving and spring settings come from direct involvement in events such as the WTCC rather than generic road-car tuning carried over to a track option. For cars carrying more aggressive upgrades – the kind of modification list you’d see on a factory racing entry or an A-class competition car – XYZ Racing also offers custom-built shock absorbers rather than a fixed off-the-shelf spec. That route means supplying details of what else has been changed on your WRX or STI and which circuit you’re running, so the damper can be built around your actual car rather than a generic AWD template.

Fitment for the Subaru Impreza WRX/ WRX STI AWD 4WD (2015-2021)

This kit is built for the SU12-chassis Subaru Impreza WRX and WRX STI, all-wheel drive, covering the 2015 to 2021 model years. Confirm your build year falls within that span before ordering, since Subaru revised suspension geometry across Impreza generations and a Racing Spec kit for one chassis code won’t carry over to another.
