XYZ Racing Street Advanced Coilovers — Subaru IMPREZA GDB STI D-F (PCD: 5 X 114.3) 4WD 2005-2007

The GDB STI’s symmetrical all-wheel-drive layout puts weight low and forward through the nose, and every Hawkeye-era owner knows the moment: trail-brake into a hairpin and the front end wants to push wide before the DCCD sorts the torque split out. The XYZ Racing Street Advanced coilover kit for this 2005-2007 Impreza GDB STI D-F is built to keep that front axle planted without turning the car into a trailer-queen for the daily commute.

Street Advanced sits in the range as the enthusiast street setup with adjustable comfort – not a stripped-out circuit special, but a kit that lets an owner firm the car up for a trackday and wind it back for the motorway run home. For a chassis so many owners still drive daily, that range of adjustment matters more than outright stiffness.

What this coilover does for your 2005-2007 Subaru IMPREZA GDB STI D-F (PCD: 5 X 114.3) 4WD

With 720 ways of damping adjustment on tap, you can tune compression and rebound to suit the job on any given day – soft enough to stop B-road ruts turning into a jarring ride, firm enough to control the nose-dive that comes with trail-braking a car still carrying a turbocharged flat-four over the front axle. Ride height adjusts independently of preload, so you can drop the stance without clipping suspension travel or upsetting the factory geometry on a car that still sees genuine road use. On a 2005-2007 GDB STI D-F, the payoff is sharper turn-in, less body roll mid-corner, and a rear end settled enough for the DCCD to put power down cleanly out of a tight apex.

About the Street Advanced coilover

XYZ Racing’s engineering team has spent years refining the Street Advanced line, running it through the brand’s motorsport programme in multiple countries before releasing it for road use. That testing under race conditions is why Street Advanced sits at the top of XYZ’s street-focused range: built for owners who want one set of dampers that copes with a normal commute and a trackday without a spanner change in between. The signature feature is 720 discrete damping positions, giving far finer control over compression and rebound than a basic 16 or 32-click adjuster, so an owner can nudge the setup incrementally rather than jumping between settings that are either too soft or too firm. On a rally-derived platform like the GDB STI, that fine adjustment range lets the kit work with the chassis’s factory AWD balance rather than fight it. XYZ positions Street Advanced as equipment for drivers chasing both pace and control from the same car, rather than picking one over the other.
