Alfa Romeo 155 Q4 TURBO 4WD Rr: Non-ride height adjustable 1992-1997 — Coilovers

The 155 Q4’s permanent four-wheel-drive layout – lifted from the Lancia Delta Integrale and hung off a nose-heavy transverse turbo four – is exactly why its suspension deserves more attention than most. Three decades on, the dampers that left Arese in the early 90s are long past their useful life, and there is no factory replacement queued up for a car this scarce. This XYZ Racing coilover package for the Alfa Romeo 155 Q4 Turbo 4WD (1992-1997) is how owners put modern, consistent damping back under one of the rarer 90s all-paw Q-cars.

Note that this is the rear-axle fitment, and on this chassis the rear unit is not ride-height adjustable. The spring seat and damper are matched to the Q4’s standard rear geometry rather than left open for slamming, which keeps the AWD driveline angles honest while still handing you a fresh damper to build the rest of the setup around.

What this coilover does for your 1992-1997 Alfa Romeo 155 Q4 Turbo 4WD

The first thing you notice is body control the tired originals surrendered years ago. The 155 Q4 carries its mass over the front axle, and a worn rear lets the tail go vague and the nose wash wide on turn-in; a fresh, matched rear coilover settles that axle so the Torsen rear diff can actually deploy drive on corner exit instead of fighting a floating platform. Over patched UK B-roads the Q4 stops crashing into compressions and starts breathing with the surface, and under boost the back end stays planted as the turbo four comes onto its mid-range. The net result is a 155 that turns in cleaner, rides flatter, and lets you trust the throttle earlier.

About the coilover range

A coilover combines the spring and damper into a single height-managed strut, replacing the separate spring-and-shock arrangement the 155 left the factory with. This XYZ Racing range for the Q4 is offered in several distinct specifications rather than one compromise setting: Super Sport and Top Sport for fast-road and track-day duty, Circuit Master and Racing Spec for harder circuit work, Tarmac Rally and Pro Rally for stage use, and Drift Spec for those chasing angle. Each specification carries its own damper valving and spring strategy suited to that discipline, so you choose the character before it ever bolts to the car. On this rear application the ride height is fixed to protect the four-wheel-drive geometry, with the tuning effort going into damping quality rather than adjustable lift. It is a coilover built to bring a 30-year-old AWD platform back to a modern standard of control.
