XYZ Racing Street Advanced Coilovers — Alfa Romeo 155 Q4 TURBO 4WD Rear: Non-ride height adjustable 1992-1997

The 155 Q4’s permanent four-wheel-drive turbo layout is the reason owners are still chasing these cars in 2026, and it is also what makes the standard suspension feel out of its depth. With the transverse 2.0 turbo four sitting ahead of the front axle and a Delta Integrale-derived driveline splitting torque to all four corners, the Q4 carries its mass high and forward. The XYZ Racing Street Advanced coilover is built to settle that nose-led weight without turning a usable Alfa into a track-only compromise.

This is the road-and-occasional-circuit option in the range, tuned for enthusiasts who drive their 155 Q4 hard but still need it to behave on a B-road or a motorway slog. It gives you control over body movement and a lower, more planted stance while keeping the damping range to civilise rough surfaces.

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

Drop the ride height and the Q4 stops leaning on its outside front under power-on cornering, so the all-wheel-drive traction you bought the car for actually translates into direction change rather than push. The 720-way damping adjustment lets you run a softer setting for daily use and firm things up for a track day without touching a spring. You feel it as flatter turn-in, less dive under braking into a hairpin, and a rear axle that stays composed when you load it mid-corner. Stance tightens up the arch gaps that age these cars too.

About the Street Advanced coilover

The Street Advanced is XYZ Racing’s most popular damper, refined over years by the company’s engineering team and proven across international race programmes before reaching production. It is specified for normal road use through to track-day duty, with 720 separate damping increments so you can match the car to the surface and the session. Construction is geared toward a wide adjustment window rather than a single fixed track setting, which is why it suits a daily-usable AWD turbo. The brief is simple: speed and control for drivers who want both, in a kit that does not punish you on the commute home.

Fitment for the Alfa Romeo 155 Q4 (1992-1997)

This kit is matched to the 155 Q4 Turbo 4WD, chassis code AL05, across the full 1992 to 1997 production run. Note the rear axle on this application is non-ride-height adjustable, so height changes are concentrated at the front while damping adjustment is available throughout. Confirm your chassis code against the listing before ordering.
