Caliper render for this kit:

The MC20 carries its Nettuno twin-turbo V6 behind the cabin, and that mid-engine mass sits squarely over the rear axle. On a car sending north of 600bhp through the rear wheels alone, the back brakes do more than trim speed: they manage heat and keep the car stable while the nose stays light. The XYZ Racing Hollow Rear Big Brake Kit for the Maserati MC20 is built to keep that loaded rear axle composed when the standard setup starts to fade.
This is the rear half of a circuit-capable braking upgrade, using two-piece floating discs to shed rotational and unsprung weight and a pad compound you select to match how you actually drive. Specify it for road miles, fast-road use, or full track work, and run it alongside the front kit for even bite from front to rear.
What this brake kit does for your 2020-2026 Maserati MC20
The two-piece floating disc strips rotating mass from each rear corner, so the wheels react to pedal inputs faster and the discs shed heat more readily across repeated heavy stops. On the MC20, where the engine’s weight loads the rear, that extra thermal headroom is what stops the pedal going long after a handful of hard laps. Choose the Racing compound for the bite and fade resistance circuit sessions ask for; the Sport compound bridges fast road and the occasional track day; the Street compound stays quiet and clean for everyday road use. What you feel is a firmer pedal and a rear axle that stays settled under heavy trail-braking into a corner.
About the Hollow rear brake kit
The Hollow rear brake kit takes its name from the hollow-bodied caliper fitted as standard, paired with a two-piece floating disc that removes material to cut rotating mass without surrendering the thermal capacity a heavy supercar demands. Serious track use is covered by the optional Hollow Racing caliper, which drops the dust cover, is rated to 1000C and carries a two-year warranty. It is offered in three pad compounds, Street, Sport and Racing, so the same hardware can serve a daily-driven MC20 or one that sees regular track time. 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 to match your build. Discs are drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable at checkout. As a rear-axle kit, supplied as a pair, it is engineered to work in concert with a matching front big brake setup, preserving the braking balance Maserati designed into the car. Each component is sized around the MC20’s rear hub and wheel package rather than adapted from a generic fitment.
Fitment for the Maserati MC20 (2020-2026)
This kit is built for the Maserati MC20 across the full 2020-2026 production run and fits the rear axle as a pair. It is designed around the car’s factory rear hub and wheel dimensions. Confirm your wheel clearance and current disc arrangement before ordering, and add the matching front kit if you want a complete front-to-rear upgrade.

Choosing your spec
Every kit is built to order around the choices you make above. Here is what each option actually changes, so you can spec yours with confidence.
Brake pads — Street, Sport or Racing
Every kit ships with a full set of high-performance pads; the compound is your call.
Street is the right default for fast-road driving — a strong, progressive cold bite with low noise, low dust and long disc life. Sport raises the working temperature and adds bite and fade resistance for hard road use and the occasional track day, while still behaving on a cold morning. Racing is a track compound built for sustained abuse: huge fade resistance and bite once heat is in it, at the cost of more noise and dust when cold. Match the pad to how hard you actually use the brakes — there is no benefit to a race pad that never gets up to temperature.
Caliper grade — Hollow vs Hollow Racing
Hollow is the standard caliper on every kit: a hollow-body forged caliper, lighter than a solid one, fitted with a dust cover and backed by a 5-year oil-leak warranty. For most fast-road and spirited track use it is all the caliper you need.
Hollow Racing is the track-grade upgrade. It runs the same hollow body but without a dust cover (so there is nothing to melt at sustained high temperature), uses a twin-metal piston that isolates heat travelling from the disc to the oil seal, and is rated to 1000°C. Available 330–356mm (rear). Warranty is 2 years on oil leaks and 10 years on appearance. Built for professional racing and repeated track days.

Caliper colour & finish
Painted colours (Red, Yellow, Gold, Black, Anodized Black) are included at no cost. Want an exact match to your car? Custom Color (+£150) paints the calipers to any Pantone code you supply (15–20 day lead time).
Polished Forged finishes are the flagship: a forged caliper given a mirror-polished surface treatment that shifts colour with the viewing angle. Beyond the looks, the polished surface dissipates heat better, resists rust and stands up to the weather. Choose Titanium (neochrome, +£350), Polished Gold (+£300) or Polished Silver (+£250). They look their best paired with a titanium centre bell. Care: clean only with a dilute neutral cleaner or water.
Candy colours (+£200) use a deep candy-paint and polishing process for a mirror-reflection, boutique finish — pick Teal, Blue, Red or Orange (shown below right).


Centre bells
The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. The standard anodized centre bell is included. The Two-tone bell (+£200) adds an anodized accent ring — choose Red, Yellow, Orange, Purple or Silver right here at checkout. The Titanium centre bell (+£500) is a forged titanium bell (bolts not included) that finishes off the polished-forged look.
