XYZ Racing Street Advanced Coilovers — Porsche 996 CARRERA-4/4S 1998-2001

The 996 Carrera-4 and Carrera-4S share one defining fact with every 911 that preceded them: the flat-six sits behind the rear axle, concentrating mass where the rear suspension has to work hardest under braking, corner entry, and trailing throttle. The 4S adds a second layer with its Turbo-width bodywork and Porsche Traction Management’s all-wheel drive – a genuinely different car to set up compared to the narrow-body RWD variants, and one that responds clearly to suspension quality.

The XYZ Racing Street Advanced coilover for the 996 Carrera-4/4S brings 720-way damping adjustment and ride-height control together in a single package – developed and refined over years by XYZ’s professional engineering team and validated through testing in competitive racing environments worldwide before reaching road application.

What this coilover does for your 1998-2001 Porsche 996 CARRERA-4/4S

A 911’s rear-biased weight distribution means the rear dampers carry a disproportionate share of load through braking and cornering. With 720 adjustable damping positions, you can tune the Street Advanced to suit your use – softer for daily work on UK roads, firmer for a trackday – without fitting different hardware. The Carrera-4/4S’s AWD system manages traction across axles, but how well it does that depends on consistent suspension behaviour through a corner; properly configured damping lets PTM respond to grip rather than reacting to the car pitching and rolling underneath it. A modest ride-height reduction lowers the 996’s centre of gravity, which is meaningful on a car already managing a pendulum dynamic at its tail.

About the Street Advanced coilover

The Street Advanced is XYZ’s most popular and developed road-and-trackday coilover line, the product of years of refinement by XYZ’s professional engineering team. The headline specification is 720-way damping adjustment – 720 discrete positions spanning a range wide enough to cover a relaxed daily setup at one end and a stiffer circuit configuration at the other. XYZ ran this product through professional racing environments worldwide to prove performance before road release, and that testing background informs both the adjustment range and the damper architecture. The Street Advanced targets drivers who want to run the same car to work and to a circuit, with enough range between the adjustment limits to make that transition genuinely count rather than being a cosmetic difference.

Fitment for the Porsche 996 CARRERA-4/4S (1998-2001)

This Street Advanced kit is specified for the Porsche 996 Carrera-4/4S (chassis code PO02), covering the 1998-2001 production window – the original pre-facelift 996 generation with its distinctive headlamp treatment and the wider Turbo-width bodywork on the 4S variants. Both the narrow-body Carrera-4 and the wide-body Carrera-4S are covered under this fitment. The later 996.2 generation from 2002 onward used a revised front end and falls under a separate listing.
