Caliper render for this kit:
The 8J TT quattro has always punched above its coupé weight on a circuit. With quattro AWD through a Haldex transfer unit and a chassis short enough to feel genuinely nimble, the limiting factor on track was rarely grip. It was the OE front brakes losing pedal feel once heat built in the discs during repeated hard stops. The XYZ Racing Hollow front big brake kit addresses that directly, designed for the 8J TT 4WD variants fitted with a two-piece OE front caliper.
That two-piece caliper distinction matters here. Not every 8J TT left the factory with the same front braking hardware, and this kit’s mounting geometry is built around that specific architecture. It is a single-axle front kit, supplying a matched pair of front calipers and front discs, with three pad compounds let you specify what the car needs at the point of order rather than retrofit later.
What this brake kit does for your 2006-2014 Audi TT 4WD (8J)
The 8J quattro’s front axle handles a disproportionate share of braking energy. The Haldex system distributes drive rearward only reactively, which means on initial brake application the front end is taking the load alone, particularly pronounced on the heavier quattro variants. A larger two-piece floating disc and the right compound close the fade window that opens on track, and the floating construction keeps pad contact even as the rotor expands with heat.
Sport raises the heat threshold noticeably over Street; Racing extends it further for drivers actually pushing the 8J at circuit pace; and Street remains the quiet, low-dust default for road miles. Discs are offered drilled or slotted at the same price. Caliper finish runs from the included painted colours of Red, Yellow, Gold, Black and Anodized Black at no extra cost, through Custom Color in any Pantone, to premium polished-forged and candy options, giving the installation a finished look visible through the spokes of the 8J’s alloys.
About the Hollow Front Brake Kit
The Hollow is XYZ Racing’s front brake upgrade line, built around direct fitment to the factory caliper mounting points. The caliper is hollow-bodied as standard, paring weight from the corner without surrendering clamping force, and the hollow-vane two-piece discs shed heat faster than a solid casting. Three compound tiers cover the full range from daily wet-weather braking through to sustained high-load circuit stops, and compound is selected at configuration rather than sourced separately, so the kit arrives ready for its intended use.
The caliper finish choices sit within the same brake architecture, so both performance and visual specification are locked in at one order. For serious track use, the optional Hollow Racing caliper upgrade runs without a dust cover, is rated to 1000C and carries a two-year warranty. Centre bell upgrades in two-tone anodized colours or titanium are selectable at checkout, and braided lines round out the build. For a car the size and weight of the 8J TT, the front brake spec is the single upgrade that most changes braking confidence under load.
Fitment for the Audi TT 4WD (8J) (2006-2014)
This front big brake kit fits the Audi TT 4WD (8J) quattro, covering model years 2006 to 2014. Fitment is strictly limited to 8J variants originally equipped with a two-piece OE front caliper; if your car left the factory with a single-piece OE caliper, this kit will not mount correctly. Confirm your front caliper type before ordering, as this is not a detail to estimate from trim level alone.

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 286–380mm (front). 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.
