XYZ Racing Circuit Master Coilovers — Porsche 964 CARRERA-2 1991-1994

The 964 Carrera-2’s rear-engine layout puts roughly 60 per cent of the car’s weight behind the rear axle – a geometry that makes damper specification critical in a way that simply does not apply to a front-engined saloon or mid-engine sports car. In sustained circuit use, where repeated hard braking loads and unloads the rear axle across dozens of corners, the standard 964 tune was set for grand touring rather than lap-time work. The pendulum physics that made this car both captivating and unforgiving on the road are the same forces a circuit-spec coilover needs to address with precision.

The XYZ Racing Circuit Master coilover kit for the Porsche 964 Carrera-2 1991-1994 is built for exactly that environment. Where most road-use coilover kits offer a simple ride-height drop and two-way adjustment, the Circuit Master provides 9,720 distinct adjustment combinations from a three-knob system – giving you granular, independent control over the car’s damping character at each axle.

What this coilover does for your 1991-1994 Porsche 964 CARRERA-2

The three-knob system lets you separate front and rear damping responses – essential on a platform where the rear axle must simultaneously handle drive loads from the flat-six and manage the inertia of the engine mass hanging behind it. Set your ride height to shift the centre of gravity, then calibrate rear rebound independently from front compression to control how quickly weight returns to the driven wheels after a braking event. On corner entry, a correctly configured 964 C2 rotates predictably; an incorrectly compressed one snaps or pushes wide depending on how aggressively it has been lowered. With 9,720 adjustment options available, the Circuit Master spans the range from an aggressive circuit configuration to a road-usable fast-track setting without requiring a different damper for each use.

About the Circuit Master

The Circuit Master sits at the head of XYZ Racing’s competition product range – the specification platform shared with the brand’s Racing Spec, Drift Spec, and Tarmac Rally variants. Its 9,720 adjustment combinations emerge from three independent control knobs rather than a single catch-all dial, which provides an operating envelope considerably wider than a conventional two-way setup. One design characteristic worth knowing: the third knob uses a small oil hole configuration, meaning damper oil travels through a restricted passage over large inputs – this can produce a faint mechanical sound under those specific conditions. On circuit, where surface irregularities are predictable and the car’s operating loads are consistent, the design is entirely in its element. XYZ’s own racing teams have validated the Circuit Master across international competition over an extended development period, with the production kit reflecting that accumulated data.

Fitment for the Porsche 964 CARRERA-2 (1991-1994)

This kit is built specifically for the Porsche 964 Carrera-2, chassis code PO10, covering the full production run from 1991 to 1994. The C2 designation is relevant to fitment: the rear-wheel-drive layout carries different weight distribution and rear axle loading characteristics from the Carrera-4, and this kit is specified for the C2’s geometry – it is not a shared application across both drivetrain variants.
