XYZ Racing Rear Brake Kit — Kia CARNIVAL (KA4) (2020-2026)

The fourth-generation KA4 Carnival carries serious mass for an MPV, a long-wheelbase people-carrier that spends most of its life fully laden with passengers, luggage and, more often than not, a trailer behind it. All of that has to be scrubbed off by the brakes, and on a nose-heavy front-drive platform it is the rear axle that runs out of thermal headroom first on long motorway descents and repeated heavy stops.

The XYZ Racing rear brake kit for the Kia Carnival (KA4) targets exactly that weakness. It is a rear-axle pair built around larger two-piece floating discs that add swept area and shed heat more readily than the factory rears, with a choice of Street, Sport or Racing pad compounds so you can match the setup to how hard your Carnival actually works.

What this brake kit does for your 2020-2026 Kia Carnival (KA4)

The most noticeable change on a heavy MPV is pedal consistency under sustained load. The bigger rear discs give the back axle more thermal mass, so a fully loaded Carnival holds a firm, predictable pedal down a long gradient instead of going soft as the standard rears heat-soak. The hollow-vane disc casting trims rotating and unsprung weight at each rear corner, which helps the suspension settle more quickly over poor surfaces. Choosing the Sport compound sharpens everyday response, while the Racing compound raises the temperature ceiling for owners who tow heavy or cover demanding routes. The painted caliper finishes, plus custom, candy and polished-forged options, let the kit suit the look of the car.

About the Hollow rear brake kit

This is a rear-position pair engineered to lift braking capacity on a vehicle that is heavier than the cars most aftermarket kits are designed for. The hollow-vane disc casting reduces mass without giving up the surface area needed to absorb and release heat across repeated stops. The kit pairs those two-piece floating discs with fixed calipers and a graded pad menu: Street for stock-like behaviour, Sport for stronger road bite, and Racing for the highest heat tolerance. The caliper is hollow-body as standard, with an optional Hollow Racing upgrade for the hardest use that drops the dust cover, is rated to 1000C and carries a two-year warranty. Calipers are painted at no extra cost in Red, Yellow, Gold, Black or Anodized Black, with a Custom Color in any Pantone for £150 and premium polished-forged (Titanium, Polished Gold, Polished Silver) or candy (Candy Teal, Candy Blue, Candy Red, Candy Orange) finishes. Discs come drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable at checkout. The intent is straightforward: give the rear axle of a large MPV enough thermal capacity to resist fade when the vehicle is working at the top of its load and towing limits.
