XYZ Racing Street Advanced Coilovers — Subaru IMPREZA GDA/GDB STI A-D/GGA/GGB (PCD:5 X 100) 2WD/4WD 2000-2007

The GD-platform Impreza puts its EJ flat-four ahead of the front axle, and that weight bias defines how these cars behave when you push them: noticeable dive under braking, a front end that loads up early in a corner, and a tail that only comes alive once you trust the symmetrical AWD to put the power down. Factory damping on the 2000-2007 STI was tuned soft for rally-derived compliance, which is exactly what owners start chasing out once the road gets interesting.

XYZ Racing’s Street Advanced coilover is built for that owner – the one who drives a Subaru Impreza GDA/GDB STI hard on the road and the occasional track day, but still wants it to behave on a Monday commute. It is a height- and damping-adjustable kit aimed at sharpening body control without stripping out the everyday usability that makes a GD-chassis Scooby liveable.

What this coilover kit does for your 2000-2007 Subaru Impreza GDA/GDB STI

Drop the ride height and you pull the centre of gravity down over that nose-heavy boxer, which immediately cuts the dive and the front-end roll the GD is known for. The 720-way damping range lets you run a softer setting for broken B-roads and wind it firmer for a circuit session, so the same car copes with both. Tighter damping control keeps the front tyres loaded more consistently through long corners, and the AWD has a more settled platform to deploy traction from on corner exit. Braking feels more planted too, with less forward pitch as the nose stops burying itself under hard stops.

About the Street Advanced coilover

The Street Advanced sits at the heart of XYZ Racing’s range, refined over several years by the company’s own engineering team and validated in international competition before reaching production. It is set up specifically for cars that split their life between normal road use and track days, rather than a stripped-out race-only build. The headline figure is 720 damping adjustment positions, giving a genuinely wide spread between comfort and control from a single set of dampers. The design goal is straightforward: usable speed and confident control for drivers who want more from the car than the factory setup allows, without giving up the ability to drive it every day.
