XYZ Racing Top Sport Coilovers — Ktm X-BOW GT-XR 2023-2026

The KTM X-BOW GT-XR is a homologated GT4 racer with number plates – a 1,530kg carbon-tubbed missile built around Audi’s 2.5 TFSI five-cylinder, geared for a circuit first and a B-road second. That puts the GT-XR in an awkward spot for fast-road buyers: the factory damping is calibrated for slicks and smooth Tarmac, not the broken surfaces and elevation changes of a UK trackday-and-drive-home weekend. The XYZ Racing Top Sport coilover for the KT01-chassis GT-XR is built for exactly that brief.

This is the kit for an owner who actually drives the car – to Donington, around it, and back – rather than trailering between sessions. Top Sport is XYZ’s circuit-leaning street setup: more damping authority than the road-biased Super Sport, more compliance than the Racing series, and adjustable enough that you can soften it for the M40 and stiffen it for Friday testing.

What this coilover does for your 2023-2026 Ktm X-bow Gt-xr

XYZ’s brief on Top Sport is a 30 to 50 per cent damping increase and a roughly 2 kg/mm spring-rate lift over a street setting, which transforms how the GT-XR copes with uneven pavement at speed. On a car this stiff and this low, the gain you feel first is composure over mid-corner bumps – the chassis stops skipping wide and starts tracking through compressions instead of being deflected by them. Tyre contact patch becomes the dominant factor in lap-time on the GT-XR’s 245-section fronts, and damping that controls the wheel rather than the body is what protects it. You retain the GT-XR’s pointy turn-in, but with a usable window of compliance for road work that the standard setup simply does not give you. Corner-balanced and height-adjusted, the car sits properly on its springs at your driver weight with a half-tank.

About the Top Sport coilover

Top Sport is XYZ Racing’s circuit-leaning street platform – the damping and spring rates are lifted from the company’s race programme rather than developed in isolation for the catalogue. The construction prioritises damping authority over softness: the brief is to absorb a serious hit, then settle the body immediately rather than letting it pitch through a second oscillation. Spring rates are set roughly 2 kg/mm above a comfort-street kit, with damping calibrated to that rate so the assembly works as a system rather than a parts list. The intended use case is exactly what XYZ states – track days and aggressive driving – which on a homologated race car like the GT-XR means the kit is configured for the kind of mid-paced trackday driver who wants more grip and stability than stock, without committing to a slick-tyre-only race damper.
