Caliper render for this kit:

The Mk4 Golf’s nose-heavy, front-driven layout leaves the rear axle doing comparatively little of the stopping work, and the standard 1.8T rear discs are sized for commuting rather than repeated hard braking. This XYZ Racing rear big brake kit for the Volkswagen GOLF 4 1.8T puts a larger, better-cooled disc and a proper performance caliper on the back of the car, so the rear contributes its share under heavy braking instead of fading early.
For a fast-road or track-leaning 1.8T, that rear capacity changes how the car settles into a corner. With more consistent rear bite, you trail the brakes deeper without the back end going light, and the whole platform feels more planted on turn-in.
What this brake kit does for your 1998-2003 Volkswagen GOLF 4 1.8T
After fitting, the most obvious gain is rear braking that holds up to repeat stops rather than going soft after a few hard applications. The hollow-vane disc trims rotating and unsprung mass at the rear, which sharpens response and eases the load on the suspension. Three pad compounds let you match bite and temperature range to how the Golf actually gets used, from daily duty to lapping days: Street for quiet, low-dust road running, Sport for spirited fast-road work with the heat range for occasional track use, and Racing for sustained circuit temperatures. Pedal feel firms up and stays predictable as the brakes get hot, which is exactly what a 1.8T owner needs when braking from speed into a tight UK circuit complex.
About the Hollow Rear brake kit
The kit pairs a two-piece floating rear disc, vented through a hollow-vane core, with a performance caliper engineered for the Mk4 platform’s rear hub. The disc sheds weight versus a solid item while keeping the swept area and cooling needed for sustained work, reducing rotating mass where it matters on a front-drive chassis. The caliper is hollow-bodied as standard, with a Hollow Racing upgrade for harder use that drops the dust cover, is rated to 1000C and carries a two-year warranty. Pad choice spans three compounds, Street for road use, Sport for spirited driving and occasional track, and Racing for track temperatures, so the same hardware suits very different demands. Faces come drilled or slotted at the same price, and calipers are offered in the included Red, Yellow, Gold, Black and Anodized Black at no extra cost, premium polished-forged and candy finishes, or any Pantone as a custom colour, so the rear setup reads as deliberately specified behind the wheel rather than an afterthought. It is built as a focused rear upgrade, ideally run alongside a front kit for balanced braking, and supplied as a left-and-right pair.
Fitment for the Volkswagen GOLF 4 1.8T (1998-2003)
This is a rear-position kit for the Volkswagen GOLF 4 1.8T across the 1998 to 2003 model years, covering the Mk4 (1J) chassis and supplied as a left-and-right pair. It addresses the rear axle specifically; for full balance, pair it with a matching front big brake kit on the same car.

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.
