Fits Mg G50 PLUS (2025-2026)

Brake pad compound

Street: quiet, low-dust, strong cold bite for road driving. Sport: higher temperature range and more bite for fast road and occasional track. Racing: maximum fade resistance for sustained track use (noisier and dustier cold). Match the pad to how hard you actually brake.

Disc size

Caliper grade

Hollow is the standard caliper: a lighter hollow-body forged caliper with a dust cover and a 5-year warranty. Hollow Racing drops the dust cover for sustained high-temperature use (rated to 1000°C, 2-year warranty) — the track-grade choice.

Caliper colour

Painted colours are included. Polished-forged finishes are mirror-polished forged calipers (Titanium, Gold, Silver); candy colours are a deep, mirror-reflection paint. Both are premium upgrades — fuller detail further down the page.

Disc style

Drilled discs (cross-drilled holes) vent gas and water and look aggressive; slotted discs (surface grooves) wipe the pad face clean and resist fade under sustained hard use. Same price — choose on looks or how you drive.

Centre bell

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. Standard anodized is included; a two-tone bell adds an anodized accent ring in your choice of colour; titanium is the lightest, forged option.

Carbon-ceramic rotor

Carbon-ceramic rotors are a special-order track upgrade: far lighter than steel, fade-resistant at extreme temperatures and extremely long-lived. The price follows the disc size you choose above. The standard two-piece steel rotor is included.

A loaded Mg G50 PLUS carries seven occupants and their luggage, and a large share of that braking work lands on the rear axle during long downhill runs and repeated town stops. The XYZ Racing Hollow Rear Brake Kit replaces the standard rear setup on the 2025-2026 G50 PLUS with a larger, lighter disc and a fixed caliper built to shed heat rather than store it.

This is a rear big brake kit aimed at owners who use the G50 PLUS the way it was meant to be used, fully laden, often in stop-start traffic or on motorway gradients, and who want the pedal to feel the same on the tenth stop as it did on the first. You choose the pad compound to suit how you drive, from a quiet Street pad through to a harder Racing compound.

What this brake kit does for your 2025-2026 Mg G50 PLUS

The hollow-vane disc cuts rotating and unsprung mass at the rear axle, so the G50 PLUS settles more quickly over broken surfaces and the rear suspension has less inertia to manage. The extra disc diameter and swept area add thermal headroom, which is exactly where a heavy MPV struggles: scrubbing off speed from motorway pace with a full cabin generates real heat, and a bigger rear rotor resists the fade that makes a pedal go long. Run the Street compound for everyday refinement and low dust, the Sport compound for a firmer bite and wider heat range when you carry weight regularly, or the Racing compound when the car is driven harder. The fixed caliper clamps more evenly than a sliding unit, keeping pad wear consistent across the rear axle.

About the Hollow rear brake kit

The Hollow rear brake kit takes its name from its two-piece floating disc: the hollow-vane rotor is lightened internally to drop mass without surrendering the swept area you need for heat capacity. It is a rear-axle-specific kit, a pair of rear discs and calipers sized for the G50 PLUS rear hub rather than adapted from another platform, which keeps front-to-rear balance and clearances correct. The caliper body is hollow as standard, with an optional Hollow Racing upgrade for serious track use, rated to 1000C with no dust cover and a two-year warranty. Three pad compounds cover the spread of use: a Street compound for refined daily driving, a Sport compound that bites harder once warm, and a Racing compound for owners who push the car hardest. Discs come drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable, and the caliper is offered at no extra cost in Red, Yellow, Gold, Black or Anodized Black, with premium polished-forged Titanium, Polished Gold and Polished Silver, candy Teal, Blue, Red and Orange, or a Custom Pantone for 150 pounds, so the visible part of the upgrade can be matched to the car or kept discreet behind the wheel.

Fitment for the Mg G50 PLUS (2025-2026)

This kit is built for the rear axle of the Mg G50 PLUS across the 2025-2026 model years. It fits the rear position only and is configured specifically for this G50 PLUS application. Confirm your model year and exact variant before ordering so the disc and caliper match your car.

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.
