Caliper render for this kit:

The E3 Cayenne sits on the MLB Evo platform it shares with the Q7, Bentayga and Urus, which means real mass over the rear axle and a chassis that leans hard on its brakes the moment a fast road opens up. The XYZ Racing Hollow Rear Brake Kit for the Porsche Cayenne (E3) (OE210) adds thermal capacity and a firmer rear bite to a 2018-2023 car that stops well from cold but starts to feel the heat on a long descent or a committed back-road run.
Two-piece floating discs cut rotating and unsprung weight at the rear axle, which is exactly where a two-tonne-plus SUV feels every kilo. This is a rear-specific kit, fitted as a matched pair, built to balance an uprated front setup or simply to restore bite and pedal consistency once the original discs and pads have had their day.
What this big brake kit does for your 2018-2023 Porsche Cayenne (E3)
Fit it and the first thing you notice is rear-end composure under hard, repeated braking, the kind a heavy Cayenne loads up on a twisting A-road or a track day. The two-piece floating discs shed rotating mass, so the rear axle reacts faster over surface changes and the steering feels a shade lighter, while the floating mount holds the rotor true as it heats. Pad choice does the rest: the Street compound stays quiet and low-dust for daily driving, the Sport compound adds bite for spirited road use, and the Racing compound holds friction when sustained heat would otherwise cook a road pad into fade. Because it works the rear axle, it lets you set front-to-rear balance deliberately instead of asking the front brakes to do everything.
About the Hollow big brake kit
The kit is built around a two-piece floating disc: rotor cores formed with internal voids to drop rotating weight while keeping a large swept area for heat to spread and dissipate. Less mass spinning with the wheel means the brakes slow and recover more willingly, and a cooler-running disc resists the warping and fade that punish a heavy SUV worked hard. The kit is offered with three pad compounds – Street, Sport and Racing – so friction level and dust behaviour can be matched to how the car is actually used, from school run to track session. Disc faces are available drilled or slotted at the same price, with the centre bell offered two-tone anodized in five colours or in titanium. Calipers are finished in a choice of Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a Pantone Custom Color for £150, so the hardware suits the car behind the wheel, and an optional Hollow Racing caliper – no dust cover, rated to 1000C, two-year warranty – is there for circuit use. The components are specified for this fitment rather than adapted from another platform, which keeps installation clean.
Fitment for the Porsche Cayenne (E3) (OE210) (2018-2023)
This kit is specified for the third-generation E3 Cayenne, OE210 reference, built between 2018 and 2023, and fits the rear axle. Confirm your exact model year and wheel size before ordering, as big brake hardware needs the right wheel diameter and barrel clearance to seat correctly. Caliper colour and pad compound are both selectable when you order.

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.
