XYZ Racing Tarmac Rally Coilovers — Porsche 964 CARRERA-2 1991-1994

The 964 introduced coil-spring front suspension to the 911 range for the first time, but the fundamental weight distribution – roughly 60 percent over the rear axle – remained unchanged from thirty years of engineering before it. On sealed stages, that rear concentration loads the driven wheels hard through compressions and rewards a damper that can absorb a large jolt without transferring the energy directly to the chassis. Lose control of that rear body movement at pace and the flat-six’s mass becomes a liability rather than a traction advantage.

The XYZ Racing Tarmac Rally coilover for the Porsche 964 Carrera-2 is built specifically around the demands of sealed-stage competition. The calibration targets the compressive forces generated by irregular tarmac surfaces typical of road-rally stages – rapid, high-energy impacts that arrive at speed and must be absorbed without unsettling the car’s attitude.

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

On rough tarmac stages, maintaining rear tyre contact is where the 964’s time is won or lost. The Tarmac Rally damper absorbs the jolt of a significant bump and suppresses the secondary body movement that follows, keeping the rear tyres loaded rather than bouncing clear of the surface. For a car where the engine sits behind the rear axle, that traction advantage compounds: a composed rear end under compression means the flat-six’s torque is going into the road rather than into a wheel that has momentarily lifted. The calibration draws from XYZ Racing’s active tarmac rally programme, not a theoretical compromise – the settings reflect what the platform needs under competitive conditions across a genuine range of stage surfaces.

About the Tarmac Rally coilover

The Tarmac Rally specification is designed around uneven-surface sealed stages, where the primary challenge is absorbing the energy of irregular tarmac and large bumps at competition speeds rather than optimising for smooth-circuit lap times. The damper construction targets high-energy compression events – absorbing the impact before it reaches the body, then controlling the rebound to prevent secondary oscillation from degrading tyre contact. Vehicle stability on cambered and broken road surfaces depends on precisely this sequence: impact absorbed, body suppressed, traction restored. Every setting across the range is derived from XYZ Racing’s tarmac rally testing programme, meaning the calibration reflects competition-derived experience on the surfaces this damper will actually encounter. For a platform as dynamically sensitive as the 964 Carrera-2, that development lineage is the difference between a kit that works and one that merely fits.

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

This kit covers the Porsche 964 Carrera-2 (chassis code PO10) from 1991 through 1994. The fitment is specific to the Carrera-2’s rear-wheel-drive suspension geometry and is not interchangeable with the Carrera-4’s all-wheel-drive front end. Confirm your build variant before ordering.
