The NQ5 Sportage carries the bulk of its mass over the nose, so on paper the rear axle looks like an afterthought. In practice that front bias is exactly why the standard rear brakes feel hazy once you load this 1.6-tonne-plus crossover up with passengers, a roof box or a trailer and start braking from real speed on a B-road. The rear end stops contributing under repeat stops, the pedal lengthens, and the front discs end up doing all the work.
This XYZ Racing rear brake kit is the answer to that imbalance. It restores rear braking authority on the 2021-2026 Sportage with larger two-piece floating discs and fixed calipers that hold their bite when the standard setup has gone soft. It is a fast-road and towing-focused upgrade rather than a stripped-out track part, which suits the way owners actually drive this car.
What this big brake kit does for your 2021-2026 Kia Sportage
You feel the rear axle pulling its weight again. With more rear clamping force and discs that shed heat through their hollow internal vanes, the pedal stays firm through a string of heavy stops instead of fading toward the floor. Brake balance shifts rearward where it belongs, which settles the Sportage under hard braking and reduces the nose-dive and front-pad punishment that a front-heavy SUV inflicts on itself. With Racing-compound pads fitted, the kit copes with sustained downhill work and loaded descents; the Sport compound covers harder road work; with the Street compound it stays quiet and clean for daily running.
About the Hollow rear brake kit
The two-piece floating disc is the defining feature: the hollow-vane casting is internally lightened and vented to drop rotating mass and pull heat away from the friction surface faster than a solid casting. That keeps operating temperatures lower across repeated braking, which is what protects the pedal feel. Three pad compounds are offered so the kit can be matched to use: Street for stock-like manners, Sport for firmer fast-road bite, and Racing for the highest fade resistance under heat. 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, so the upgrade can be hidden behind the wheel or made a visible part of the build. Discs come drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable at checkout.

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.
