XYZ Racing Drag Racing Coilovers — Subaru IMPREZA STI GRB/GVB/GRF/GVF 4WD 2007-2014

The GRB/GVB/GRF/GVF-generation Impreza STI puts its EJ257 turbo flat-four through a symmetrical AWD system built to get power down hard off the line, and that is exactly where a factory damper setup runs out of ideas. XYZ Racing’s Drag Racing coilover for the Subaru IMPREZA STI GRB/GVB/GRF/GVF 4WD (2007-2014) is built around one job: load the driven wheels the instant the light goes green and hold that load through the run.

This is not a road-and-track compromise kit. It is set up specifically for 0-400m runs, where launch traction and stability at speed matter more than mid-corner balance.

What this coilover does for your 2007-2014 Subaru IMPREZA STI GRB/GVB/GRF/GVF 4WD

On an AWD car built for symmetrical power delivery, shifting weight onto the front and rear axles at launch is what turns wheelspin into forward drive. The setting on this kit lets you load the driven tyres harder the instant you release the clutch, so the STI’s turbo flat-four stops fighting for traction and starts converting boost into distance. Cutting that initial wheel idle matters more on this chassis than most, because the EJ257 spools quickly once on boost, and torque with nowhere to go just heats the tyres instead of moving the car. Through the back half of a run, the same adjustment keeps the GRB/GVB/GRF/GVF planted at speed rather than floating on springs and dampers that were never set up for repeat full-throttle launches.

About the Drag Racing coilover

XYZ Racing’s Drag Racing coilover is built specifically for 0-400m strip work rather than the road course, and it is supplied in setups for front-, rear- and all-wheel-drive platforms alike. Instead of chasing mid-corner grip, the adjustment is built around weight transfer at launch: the setting biases load onto the driven axle the moment power goes down, so the tyre at the business end of the drivetrain compresses harder into the tarmac. On a 4WD platform like this Impreza STI, both axles benefit from that transfer rather than just one. The result is less time spent with a spinning wheel and unused torque at the start of a run, and a more settled car as speed builds toward the far end. It is a strip-specific tool, built around getting a heavy, powerful AWD car off the line cleanly rather than through a series of corners.

Fitment for the Subaru IMPREZA STI GRB/GVB/GRF/GVF 4WD (2007-2014)

This kit is built for the GRB and GVB hatchback and GRF and GVF saloon Impreza STI, chassis code SU10, across the 2007-2014 production run, covering every 4WD variant of that generation. Confirm your build year falls within that span before ordering; earlier and later STI generations use different chassis and are not covered by this listing.
