XYZ Racing Street Advanced Coilovers — Porsche 997 TURBO CARRERA-4 2005-2011

The 997 Turbo Carrera-4’s rear-engined AWD architecture creates a suspension loading profile that most coilovers are calibrated to ignore: significant mass behind the rear axle, a comparatively light front end, and Porsche’s PTM distributing torque between axles under hard acceleration. Any suspension upgrade that ignores this balance either dulls the car or amplifies the tension between front and rear traction. The XYZ Racing Street Advanced, a coilover line developed specifically for road use and track-day work, is built for exactly this spread of use.

What the 997 Turbo rewards above all else is predictable weight transfer as the flat-six spins up through boost. The Street Advanced’s 720-way damping adjustment gives owners the range to soften the car for road compliance without sacrificing the composure that makes a 480-500 bhp rear-engined machine liveable on real roads. That adjustment range is not a checkbox on a spec sheet – it is the practical tool through which a Turbo owner aligns the suspension to the way they actually drive.

What this coilover does for your 2005-2011 Porsche 997 TURBO CARRERA-4

With 720 damping adjustment positions, the Street Advanced covers the full spectrum from GT road comfort to committed fast-road dynamics – a range that suits the 997 Turbo’s dual life across motorway and mountain pass. Adjustable ride height lets owners bring the wide-body shell down to a more purposeful stance without compromising tyre clearance across the fat rear rubber. Because the PTM manages front-to-rear torque electronically, a consistent and predictable suspension platform works with that system’s calibration rather than introducing behaviour the electronics have to compensate for. On demanding roads where the Turbo’s rearward weight bias becomes most apparent through long corners, the Street Advanced keeps the nose tracking honestly without killing the planted rear feel.

About the Street Advanced coilover

The Street Advanced is XYZ Racing’s most widely deployed coilover line, developed by the company’s engineering team over several years and validated through use in professional race environments worldwide before reaching the road-use catalogue. Its defining characteristic is the 720-way damping adjustment, which gives drivers a broad window within which to find their preferred setting rather than being committed to a single factory rate. The product was built around the demands of everyday road driving and track days – a balance that makes it directly relevant to 997 Turbo owners who want genuine adjustability without a kit developed solely for circuit conditions. Construction is to OE fitment dimensions, allowing the Street Advanced to replace the factory dampers in place without modification to the bodyshell or subframe.

Fitment for the Porsche 997 TURBO CARRERA-4 (2005-2011)

This kit is specified for the Porsche 997 Turbo Carrera-4, chassis code PO04-2, across the full 2005-2011 model range. That span covers both the 997.1 and 997.2 Turbo generations. Before ordering, confirm your factory suspension specification – 997 Turbo models fitted with PASM have different damper installation requirements from cars without it.
