Fits Audi 100 QUATTRO (1985-1990)

Brake pad compound

Street: quiet, low-dust, strong cold bite for road driving. Sport: higher temperature range and more bite for fast road and occasional track. Racing: maximum fade resistance for sustained track use (noisier and dustier cold). Match the pad to how hard you actually brake.

Disc size

Caliper grade

Hollow is the standard caliper: a lighter hollow-body forged caliper with a dust cover and a 5-year warranty. Hollow Racing drops the dust cover for sustained high-temperature use (rated to 1000°C, 2-year warranty) — the track-grade choice.

Caliper colour

Painted colours are included. Polished-forged finishes are mirror-polished forged calipers (Titanium, Gold, Silver); candy colours are a deep, mirror-reflection paint. Both are premium upgrades — fuller detail further down the page.

Painted — includedTell us the exact Pantone (PMS) code you want the calipers painted.Polished forgedCandy
Disc style

Drilled discs (cross-drilled holes) vent gas and water and look aggressive; slotted discs (surface grooves) wipe the pad face clean and resist fade under sustained hard use. Same price — choose on looks or how you drive.

Centre bell

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. Standard anodized is included; a two-tone bell adds an anodized accent ring in your choice of colour; titanium is the lightest, forged option.

Carbon-ceramic rotor

Carbon-ceramic rotors are a special-order track upgrade: far lighter than steel, fade-resistant at extreme temperatures and extremely long-lived. The price follows the disc size you choose above. The standard two-piece steel rotor is included.

XYZ Racing Hollow Front Brake Kit — Audi 100 QUATTRO (1985-1990) — 380 mm
380 mm

Forty years on from the Audi 100 Quattro’s launch, the C3 generation’s front brake hardware is the weak link in an otherwise enduring chassis. The Type 44 platform combines a longitudinal inline-five mounted ahead of the front axle with the added mass of the quattro drivetrain. That nose-heavy layout places consistent demand on the front brakes under hard deceleration, and the original components are now decades removed from their design service life.

This XYZ Racing front brake kit for the Audi 100 Quattro (1985-1990) closes the gap between the car’s quattro traction and its factory stopping power, with larger hollow-vane discs, four-piston calipers, and three selectable pad compounds.

What this brake kit does for your 1985-1990 Audi 100 QUATTRO

The C3 Quattro with its AWD hardware weighs around 1,350kg, and the longitudinal five-cylinder’s mass ahead of the front axle means the front brakes carry a disproportionate share of the load. The hollow-body caliper and hollow-vane disc cut rotating and unsprung mass relative to ageing OEM hardware, sharpening pedal feedback and improving heat management across repeated stops. Two-piece floating discs let the rotor expand with heat without warping against the bell, so the pedal stays consistent as the brakes work.

Three pad compounds map to use. Street is the quiet, low-dust road default with better bite and fade resistance than standard road pads. Sport adds heat range for spirited fast-road driving and the occasional event. Racing is suited to sustained operation at historic circuit or hillclimb events where brake temperatures build through a session. Discs come drilled or slotted at the same price, and braided lines firm the pedal.

About the Hollow Front Brake Kit

The caliper is a hollow-body forging as standard, cutting unsprung mass over the worn original components while feeding back more directly through the pedal and suspension under braking. Paired with the hollow-vane disc, the kit holds working temperature through repeated stops far better than the factory items. For sustained competition use, the optional Hollow Racing caliper deletes the dust cover, is rated to 1000C, and carries a two-year warranty.

Calipers are painted in Red, Yellow, Gold, Black, or Anodized Black at no extra cost. A Custom Color in any Pantone shade is £150. Premium polished-forged finishes come in Titanium, Polished Gold, and Polished Silver, with candy finishes in Teal, Blue, Red, and Orange, so the front axle can be finished period-correct or deliberately modern behind the C3’s classic wheels. Centre bells can be upgraded to a two-tone anodized finish in five colours or to titanium. Everything is selectable above when you order.

Fitment for the Audi 100 QUATTRO (1985-1990)

This kit is built for the Type 44 platform Audi 100 Quattro, covering the 1985 to 1990 model years across both saloon and Avant body styles, supplied as a matched front-axle pair. Verify your specific variant against the application list before ordering, as brake hardware clearances can differ between sub-variants of the C3 generation. No additional fabrication is required on the Quattro drivetrain configuration within this year span.

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.
