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

The 155 Q4’s rare four-wheel-drive turbo platform changes the rules at the strip. With its Delta Integrale-derived drivetrain putting power down through all four corners, launch traction comes down to how hard you can load the driven tyres in the first few feet. The XYZ Racing Drag Racing coilover for the Alfa Romeo 155 Q4 Turbo 4WD is built for exactly that 0-400 metre window, not for kerb appeal or a softer commute.

This is the rear, non-ride-height-adjustable fitment in the kit – a focused drag setup rather than a do-everything fast-road coilover. Where a Super Sport or Top Sport spec chases corner balance, the Drag Racing series chases the standing start: controlled weight transfer, a planted rear, and tyres that bite instead of spin.

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

On a hard launch the damping is set up to shift weight deliberately between the front and rear axles, forcing greater compression onto the driven tyres at the moment it matters. That extra vertical load is what cuts wheelspin off the line – the vendor describes it as reducing the idle time of the wheel – and on a 4WD car like the Q4 it means more of the turbocharged 2.0-litre’s output reaches the tarmac instead of lighting up the contact patch. Through the traps the same setup keeps the car settled at speed, so the chassis stays composed as the rear squats and the nose goes light. You feel it as a cleaner sixty-foot and a car that tracks straight under full boost rather than wandering.

About the Drag Racing coilover

The Drag Racing series is engineered specifically for 0-400 metre acceleration runs, with variants developed for front-wheel-drive, rear-wheel-drive and four-wheel-drive cars – the 155 Q4 sitting squarely in that last group. The core principle is managed weight transfer: the damper settings let the car move mass front-to-rear during the launch so the driven wheels load up and their tyres are pressed into greater compression. That increased loading reduces the slip and spin that bleeds away a standing start, and the same control keeps the car stable as terminal speed climbs. It is a single-purpose tool – the rear unit here is non-ride-height adjustable, reflecting a setup built around a known drag ride height and launch behaviour rather than constant fiddling. Construction and valving are aimed at repeatable hard launches, not the broad road-and-track adjustability of the other XYZ Racing series.

Fitment for the Alfa Romeo 155 Q4 Turbo 4WD (1992-1997)
