XYZ Racing Circuit Master Coilovers — Alfa Romeo GIULIA 952 4WD (Modified Rear Integrated) (Cancellation Kit for Electronic Damping) 2016-2026

The Giulia 952’s factory suspension on Q4 cars leans on electronically controlled dampers talking to the DNA drive-mode selector, which is exactly the layer that has to come out before a fixed-rate coilover can do its job properly. This Circuit Master kit ships as a cancellation build for that electronic damping control, replacing the factory actuators and their wiring dependency with a fully mechanical, manually adjustable damper at each corner.

That matters on a chassis built around a 50/50 weight split and quick steering – the 952’s natural balance is already good, but the stock ECU-damped setup is tuned for comfort and stability first. Circuit Master strips that compromise out for owners doing sustained circuit lap-time work, where the car needs to hold a set attitude through a full session rather than adapt corner to corner.

What this coilover does for your 2016-2026 Alfa Romeo GIULIA

With the electronic damping control cancelled and replaced by XYZ’s own damper, the Giulia’s front end loads up predictably under trail braking instead of hunting through a compliance window designed for road use. The AWD 4WD driveline puts extra mass over the front axle versus the RWD car, and a coilover with real low-speed compression control lets you manage that nose weight into direct-entry corners without the mushiness that comes from an ageing electronic system trying to compensate in software. Ride height becomes something you set once for the car’s corner-weighted stance, not something the factory ride-height sensors fight against. Across a session, the damping stays where you left it – no ECU relearning, no drive-mode-dependent character change lap to lap.

About the Circuit Master coilover

Circuit Master is XYZ Racing’s circuit-focused damper, developed and run by XYZ’s own racing teams across international championship rounds rather than built as a road-first unit with a track mode bolted on. Each damper carries 3 external adjustment knobs feeding a shared internal circuit that between them produce 9720 distinct damping combinations, giving you separate control over compression and rebound characteristics rather than one global dial. The knobs meter oil through deliberately small passages inside the damper body; at speed over kerbs and track surface changes this can produce a faint clicking or ticking noise as oil moves through those passages, which is a normal side effect of the design rather than a fault. It’s built for repeated, sustained lapping rather than a single fast run, with the adjustment range aimed at letting a driver or engineer chase a specific balance change rather than accepting a fixed factory compromise.
