XYZ Racing Street Advanced Coilovers — Proton GEN-2 2004-2012

The Proton GEN-2’s PR01 platform carries an unusual piece of heritage for its class: the suspension geometry was shaped with input from Lotus Engineering during development, giving the car a natural balance that rewards a considered spring rate upgrade rather than resisting it. The factory damper calibration was set for compliance – Malaysian roads, long journeys, a broad ownership demographic – which leaves real headroom to sharpen without the car becoming difficult to use daily.

That gap is precisely where the Street Advanced sits. With 720 ways to adjust damping, this is a kit that lets you work through the GEN-2’s characteristics methodically rather than accepting a fixed compromise. Set the dampers firmer for a track morning, back them off for the drive home – the adjustment range is wide enough to make that a genuine option.

What this coilover does for your 2004-2012 Proton GEN-2

The GEN-2’s inherent chassis balance is one of the more underestimated assets at its original price point. Where the factory setup allows the body to load up gradually through corners – a product of comfort calibration, not any fundamental limit of the PR01 – the Street Advanced tightens response at the front axle and settles the rear more quickly over mid-corner road surface changes. Body roll reduces noticeably, which in turn makes the steering feel more direct because the tyre contact patch remains more consistent as the suspension cycles. Dropping the ride height lowers the centre of gravity, compounding the handling benefit on a platform whose geometry was always better sorted than the window sticker suggested.

About the Street Advanced coilover

The Street Advanced coilover is XYZ Racing’s most widely adopted product – developed over years by their professional engineering team and validated through competition testing at race circuits around the world before reaching the road-car market. The headline specification is 720 damping adjustment positions: a range that runs from genuinely compliant – suitable for motorway commutes and loaded cars – through to a much firmer setting for spirited track-day use, covering the full spectrum a GEN-2 owner is realistically likely to need. The construction philosophy targets drivers whose priority is speed and control in everyday conditions, without the compromises a full motorsport setup would demand on public roads.

Fitment for the Proton GEN-2 (2004-2012)

The Street Advanced kit is mapped directly to the PR01 chassis, covering the full GEN-2 production run from 2004 through to 2012. Verify your model year against the PR01 chassis code before ordering – the PR01 designation spans the complete GEN-2 range sold in this period.
