XYZ Racing Hollow Rear Brake Kit — Maserati GHIBLI (M157) (2013-2026)

The M157 Ghibli is a large rear-drive saloon that hides close to two tonnes well on the move and rather less well under repeated heavy braking. The factory rear setup is fine for commuting, but a heavy GT four-door driven hard, down a long mountain descent, on a track day, or simply loaded and quick on a B-road, asks more of the rear axle than the standard discs were specified to give. Heat builds, the pedal lengthens, and the back end stops contributing.

The XYZ Racing Hollow Rear Brake Kit for the Maserati Ghibli (M157) targets that exact problem. It is a rear-axle upgrade built to restore front-to-rear brake balance and add thermal headroom, so the Ghibli keeps slowing down properly when the fronts are fully loaded under hard deceleration.

What this rear brake kit does for your 2013-2026 Maserati Ghibli (M157)

On a car this heavy, the rear brakes do real work the moment you start trail-braking into a corner, and that is where the standard discs run out of capacity first. The two-piece floating discs in this kit cut rotating and unsprung mass at the rear while giving more swept area to absorb and shed heat. The result you feel is a firmer, more consistent pedal deep into a braking zone and a back axle that stays planted rather than going light as the fronts bite. Three pad compounds, Street, Sport and Racing, let you match the rear to how the car is actually used, from a quiet daily Ghibli on the Street pad, through the firmer Sport compound for fast road and the occasional track day, to the Racing compound for sustained circuit time. It is enough of a step to matter on track while staying civil for daily driving.

About the Hollow rear brake kit

The kit pairs a fixed aluminium caliper with two-piece floating discs, a construction chosen to shave weight at the corner without surrendering thermal mass where it counts. The floating disc reduces the gyroscopic and unsprung load at each rear hub, which sharpens how quickly the rear suspension reacts over uneven surfaces while keeping a generous friction surface for repeated stops. The caliper is hollow-bodied as standard, with an optional Hollow Racing caliper for sustained track sessions that drops the dust cover, is rated to 1000C and carries a two-year warranty. Pad choice runs across three compounds, Street for road, Sport for harder fast-road and occasional track use, and Racing for sustained track sessions, so the bite characteristic and heat tolerance can be set to the duty cycle. Calipers are painted in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with premium polished-forged Titanium, Polished Gold and Polished Silver, candy Teal, Blue, Red and Orange, or a Custom Color in any Pantone for £150, visible behind the Ghibli’s larger factory wheels. Discs are drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable at checkout. Everything is engineered as a direct rear-axle fitment, supplied as a pair, rather than a universal bracket-and-hope solution.
