XYZ Racing Street Advanced Coilovers — Porsche 964 CARRERA-2 1989-1990

The 964’s engineering shift from torsion bars to coil springs all round – a first in 911 history – created a suspension architecture that accepts conventional coilovers without the bespoke adaptation needed on earlier 911 generations. On the Carrera 2, with the flat-six hanging behind the rear axle and the bulk of the car’s mass loading the rear wheels, spring rates and damping settings carry outsized consequences: they determine whether the 964 rotates accurately into a corner or develops the pendulum behaviour the rear-engine layout can produce at corner exit.

The Street Advanced is the series for owners who run these cars hard – frequent fast-road use, occasional circuit days – without wanting to surrender usability between the two. For a 1989 or 1990 Carrera 2, now over 35 years old and a car that many owners drive rather than store, the emphasis on street capability alongside genuine performance adjustment is the right balance.

What this coilover does for your 1989-1990 Porsche 964 Carrera-2

Height adjustment lowers the 964’s centre of gravity and reduces the body roll that works against the rear-heavy balance in fast corners. The 720-way damping adjustment gives you control over how the car responds to surface changes – softer settings for road use where kickback through the rear axle can unsettle the chassis, firmer settings for circuit sessions where body motion control becomes the priority. With the 964’s rear-engine weight distribution, even modest changes to rear damping stiffness produce noticeable shifts in how the car rotates: the 720-position range gives enough granularity to find what works for this specific layout rather than accepting a fixed compromise.

About the Street Advanced coilover

The Street Advanced is XYZ Racing’s most widely adopted series, developed over years by the company’s engineering team and validated at circuit level before production. The 720-way damping adjustment defines what it is: not a two-position fast-or-slow system, but a genuine performance tool that covers road use and track day sessions from the same hardware. XYZ Racing built the series around regular-use owners who need the ability to recalibrate between driving contexts without specialist intervention. That adjustment range reflects a product iterated against real performance conditions – circuit testing was central to the development process, not an afterthought, and the series carries that provenance into the road-biased spec that Street Advanced is designed to deliver.

Fitment for the Porsche 964 Carrera-2 (1989-1990)

This Street Advanced kit is built for the Porsche 964 Carrera 2 on chassis code PO09, covering the 1989 and 1990 model years – the opening period of the 964 generation before the wider 964 range expanded. The Carrera 2 designation is rear-wheel drive; this kit is specific to the C2 and is not cross-compatible with the concurrent Carrera 4 AWD model. Confirm your car’s build year falls within this window before ordering.
