Caliper render for this kit:
The Audi TT RS 8J carries its weight forward. The 2.5-litre inline-five sits ahead of the front axle, and the quattro drivetrain uses every bit of that traction to dispatch 60mph in under four seconds. On the road, the standard brakes are adequate. Take the same car onto a circuit and the picture changes: an AWD system this effective means you are always accelerating later and harder into each braking zone, and the front brakes pay for it in heat.
The XYZ Racing Hollow Front Big Brake Kit is built for that duty cycle. It is a single-axle front kit, supplying a matched pair of front calipers and front discs. Three pad compounds run to full racing spec, caliper finishes span included painted colours through to premium options, and the hollow-vane two-piece disc cuts rotating mass at the axle that matters most on this chassis.
What this brake kit does for your 2009-2014 Audi TT RS 8J
The hollow-bodied calipers and two-piece floating discs reduce unsprung and rotating mass at an axle already carrying engine, gearbox, and quattro centre differential, cutting the inertia the suspension has to manage over mid-corner surfaces. Greater swept area compared to the standard 8J front discs improves heat distribution under repeated hard stops, keeping pedal feel consistent across a track session, while the floating construction lets the rotor expand evenly with heat rather than coning.
Three pad compounds let you run a harder friction rating on circuit days without committing to one that bites cold poorly on the Monday commute. Street is the quiet, low-dust road default, Sport adds bite and heat range for fast-road work with the occasional track day, and Racing is the dedicated circuit compound. Discs come 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 that close the loop between brake hardware and exterior colour.
About the Hollow Front Brake Kit
The caliper is hollow-bodied as standard, and the two-piece disc is cast with internal cavities rather than solid faces, removing material and therefore mass without reducing the swept area that governs braking performance and thermal capacity. On a front-heavy quattro platform like the 8J TT RS, the front axle carries significant static load, and every kilogram saved in unsprung mass helps the suspension respond more accurately to surface changes mid-corner.
The three-compound pad selection covers the full range from a single kit: Street beds in quickly and suits everyday road use; Sport offers sharper initial bite for fast-road and occasional track; Racing is tuned for sustained high-temperature operation where friction consistency under repeated stops counts more than cold-bite response. All three share the same caliper mounting geometry, so switching between them requires no hardware changes beyond the pads. For serious circuit 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, alongside braided lines.
Fitment for the Audi TT RS 8J (2009-2014)
This front big brake kit is machined specifically for the Audi TT RS 8J across the full production run, 2009 to 2014. The TT RS front hub assembly differs from the standard TT and TTS of the same 8J generation, so confirm the RS chassis designation before ordering. Check wheel clearance against your rim choice before fitting, as big brake disc dimensions may exceed the clearance of some aftermarket wheel profiles.

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.
