XYZ Racing Hollow Front Brake Kit — Mercedes Benz GT43 AMG 4-Door Coupe (X290) (2018-2026)

The X290 GT43 AMG 4-Door pushes towards two tonnes on the scales, with the M256 inline-six sitting well forward on the platform. That nose-forward weight distribution concentrates braking loads heavily onto the front axle, and on a car capable of this kind of pace, the factory front brake specification reaches its limits noticeably sooner than the engine does. Push the GT43 hard on a track day or a sustained fast-road run and the first thing that reminds you of the platform weight is pedal feel.

This XYZ Racing front big brake kit is built around that problem. It is a matched pair of left and right front calipers and two-piece floating discs, sized to the X290 front hub, that dissipates heat far more efficiently than the standard hardware and keeps pad-to-rotor temperatures in range during repeated hard stops. A choice of pad compound lets the kit be matched precisely to how the car is actually used.

What this brake kit does for your 2018-2026 Mercedes Benz GT43 AMG 4-Door Coupe (X290)

On the X290 platform, the front axle manages the bulk of braking effort, particularly given the weight distribution the GT43’s engine layout creates. The hollow-vane rotor reduces the thermal build-up that causes fade and inconsistent pedal response when the brakes are working hard across repeated heavy stops, while the two-piece floating disc lets the friction ring expand without distorting and trims rotating mass at the front corners. The three compounds extend the kit’s range considerably: Street is the quiet, low-dust road default that handles daily use cleanly, Sport suits owners who blend motorway driving with spirited sessions and need more bite and heat range, and Racing is the track compound for serious circuit running where heat cycles are sustained and frequent. Disc faces are offered drilled or slotted at the same price, so the look stays your choice.

About the Front Brake Kit

The two-piece floating rotor extracts heat from the disc faster than a solid casting manages under load, a meaningful advantage on a heavy GT platform where accumulated braking energy can overwhelm factory-sized hardware. The caliper is hollow-bodied as standard, light and stiff to resist flex, with an optional Hollow Racing upgrade for committed track use that deletes the dust cover, is rated to 1000C, and is backed by a two-year warranty. Braided lines firm the pedal, and centre bells can be upgraded to two-tone anodizing in five colours or titanium at checkout.

Caliper finish starts with the included painted colours, Red, Yellow, Gold, Black, and Anodized Black, at no extra cost, with a Custom Color in any Pantone for an additional 150 pounds. Premium polished-forged finishes (Titanium, Polished Gold, Polished Silver) and candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange) let the installation sit correctly behind AMG-specification wheels rather than looking like a retrofit.
