Caliper render for this kit:

The first-generation CX-5 KE carries its mass high and well forward, a front-drive SkyActiv crossover that pitches hard onto its nose the moment you lean on the brakes. On the standard setup that leaves the rear axle doing relatively little, which is fine for a school run but tells a different story when the car is loaded with passengers and luggage and being hauled down from motorway speed. The XYZ Racing Hollow Rear Brake Kit for the Mazda CX-5 2WD (KE) is aimed squarely at that rear-axle shortfall.
This is a rear-specific upgrade, a pair of left and right rear calipers with matched discs, built to put the back brakes back to work on a tall, heavy 2WD platform. More thermal capacity behind means the rears keep contributing through repeated hard stops instead of giving up early and dumping everything onto the front discs. You choose the pad compound to match how the car actually gets used.
What this big brake kit does for your 2015-2017 Mazda CX-5 2WD (KE)
The most useful gain on a crossover this size is consistency. A larger rear disc holds more heat before performance drops off, so a loaded CX-5 KE on a long descent or a series of quick stops keeps a firmer, more predictable pedal. Better rear contribution also steadies the car under braking, with less of the dive and front-end overload you feel when the back axle is barely involved. The three pad compounds let you set the bite you want: the Street compound for quiet everyday running with low dust, the Sport compound for keener response and a wider heat range on spirited roads, and the Racing compound when the car sees harder, hotter use. Painted caliper finishes included at no extra cost (Red, Yellow, Gold, Black and Anodized Black) plus Custom Color and the premium ranges mean the upgrade looks deliberate behind the rear wheels rather than an afterthought.
About the Hollow Rear Brake Kit
The Hollow Rear Brake Kit is a bolt-on rear-axle package for the CX-5, pairing an uprated two-piece floating disc with a matched caliper sized for the back of this chassis. The hollow caliper body and disc design trim unsprung and rotational mass while keeping the thermal capacity needed to resist fade, which matters on a heavier SUV body where the brakes have real weight to manage. Discs are offered drilled or slotted at the same price, with two-tone anodized centre bells in five colours or titanium selectable at checkout. The kit ships with a choice of three pad compounds, Street, Sport and Racing, so the same hardware suits a daily driver, a fast-road car or something that gets pushed harder. The hollow-body caliper is standard, with an optional Hollow Racing upgrade rated to 1000C, no dust cover and a two-year warranty for track duty. Caliper colour is specified when you order: the included painted finishes through to a custom Pantone. Because it addresses the rear axle only, it is designed to work alongside the existing front brakes to sharpen overall balance rather than simply add outright size for its own sake.

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.
