Caliper render for this kit:
The KU-generation Custo carries one of the longer wheelbases in the MPV class and, in seven-seat trim with the 2.0T engine, puts well over 1,800 kg against the road fully laden. Front-wheel drive means the front axle absorbs most of that kinetic energy every time the driver slows, and the factory hardware is sized for measured, everyday use rather than sustained or repeated heavy stops.
The XYZ Racing front brake kit for the 2021-2026 Hyundai Custo/Custin brings upgraded hardware to a platform where the front brakes are never far from their thermal ceiling under real effort. Three pad compounds and a choice of caliper colour make this a configurable upgrade, not an off-the-shelf box-swap.
What this brake kit does for your 2021-2026 Hyundai CUSTO/CUSTIN (KU)
Load the Custo to capacity and drive hard on an A-road or mountain descent and the stock front brakes are quickly working beyond their design brief. The two-piece floating discs in this kit dissipate heat through the rotor body more efficiently than a standard vented unit, delaying fade onset under sustained use. The Street compound covers daily driving with quiet, low-dust manners; the Sport compound raises the effective operating temperature range and adds bite while maintaining cold-morning usability; the Racing compound is calibrated for higher heat cycles on driving days or circuit events. Caliper colour is set when you order, with Red, Yellow, Gold, Black and Anodized Black all included at no extra cost to give the installation presence through the front wheels.
About the Hollow Front Brake Kit
The two-piece floating disc construction moves heat away from the swept face more aggressively than a conventional single-piece vented unit. The caliper is a hollow-body forging as standard, fed by braided lines. On a front-heavy FWD vehicle carrying the mass of a large MPV, the front rotor surface sees significant thermal cycling during any drive involving more than casual braking, and the disc geometry reduces the temperature differential between friction surface and disc body, which is the mechanism that drives fade. Three pad compounds (Street, Sport and Racing) allow the buyer to configure friction characteristics to their actual driving demands. For serious track use the optional Hollow Racing caliper deletes the dust cover, is rated to 1000C and carries a two-year warranty. Discs come drilled or slotted at the same price, the centre bell can be upgraded to a two-tone anodized finish in five colours or to titanium, and beyond the included caliper colours you can specify a Custom Color in any Pantone for £150, premium polished-forged finishes (Titanium, Polished Gold, Polished Silver) or candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange), accommodating most build aesthetics.
Fitment for the Hyundai CUSTO/CUSTIN (KU) (2021-2026)
This kit is designed for the Hyundai Custo and Custin on the KU platform, covering model years 2021 through 2026. Both the 1.5T and 2.0T engine variants share the same front hub and brake architecture, so fitment is consistent across the powertrain range. Confirm the KU chassis designation on your vehicle identification plate before ordering.

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 286–380mm (front). 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.
