XYZ Racing Top Sport Coilovers — Mercedes-Benz AMG GT S/ GT C (Cancellation Kit for Electronic Damping) 2015-2023

The AMG GT S and GT C left the factory with adaptive electronic dampers as standard, which is precisely the problem for anyone who wants to set the car up by feel rather than by algorithm. This Top Sport kit is built as a cancellation solution for that system, replacing the factory electronic damping with a manually adjustable coilover set-up that responds to spring rate and damper clicks, not a control module guessing at road surface.

Aimed at occasional track day use without giving up the daily commute, the Top Sport spec sits between full race hardware and a soft street kit. On a front-engine, rear-transaxle car like the GT S/GT C, where weight is spread close to 50/50 but still loads the rear axle hard under power, getting the damping and spring rate right at both ends matters more than on a nose-heavy hatch.

What this coilover does for your 2015-2023 Mercedes Benz AMG GT S/ GT C

Fitted to the ME54-C chassis, this kit raises damping by roughly 30-50% and spring rate by around 2kg/mm over the standard street setting, which changes how the car deals with mid-corner compressions and motorway expansion joints alike. On the road that shows up as tighter body control under trail braking into a roundabout, with less of the vertical float the factory adaptive dampers allow when they’re not in their firmest mode. On track, the stiffer spring rate keeps the outside tyre loaded more consistently through direction changes, which on a car putting big V8 torque down through the rear axle is where traction is actually won or lost. Because the electronic damping is cancelled rather than left in place alongside the coilovers, there’s no conflict between two systems trying to control the same corner.

About the Top Sport coilover

XYZ Racing built the Top Sport range around its own track-day testing, tuning the damping and spring increase to absorb sharp impacts – potholes, kerb strikes, broken tarmac – without transmitting the full hit through to the chassis, while still suppressing body movement enough to keep the contact patch working. The result is aimed squarely at drivers who want aggressive handling on track without the car becoming unlivable on the way there. Construction and adjustment range are set for repeatable behaviour across a session rather than a single hot lap, and the spring/damper balance is calibrated as a matched pair rather than picked independently.

Fitment for the Mercedes Benz AMG GT S/ GT C (2015-2023)

This kit is specified for the ME54-C chassis covering the AMG GT S and GT C variants built between 2015 and 2023, and includes the cancellation components needed to remove the factory electronic damping control rather than run alongside it. Confirm your specific GT S or GT C trim against the ME54-C chassis code before ordering.
