Caliper render for this kit:

The W176 A45 AMG carries a kerb weight that comfortably exceeds 1,500 kg, significant for a fast hatchback, and the front-biased 4MATIC drivetrain loads the front axle further under hard deceleration. On public roads that demand stays manageable; on a circuit, the standard AMG brake hardware starts to trade fade resistance for repeated sharp stops, and the pedal tells you when it has happened.
The XYZ Racing front brake kit addresses that directly for W176 A45 owners who use the car in anger. A matched pair of forged front calipers and two-piece floating discs, with three pad compounds, Street, Sport, and Racing, configure the kit to the actual deployment, and painted caliper colours acknowledge that the A45’s open AMG wheel design puts the caliper in full view on every set of alloys.
What this brake kit does for your 2013-2018 Mercedes Benz A Class W176 A45 4WD
The forged caliper and two-piece floating discs reduce rotating and unsprung mass on the front axle, directly relevant on the W176 platform, where the transverse engine layout concentrates weight over the front wheels and the 4MATIC system simultaneously asks those same wheels to steer and provide traction. Less mass at the wheel gives the front suspension more freedom to track camber changes and kerbing, translating to more consistent steering response under braking. Thermal capacity is the second major gain: the floating ring expands on its alloy bell as it heats, controlling coning and judder, and the disc sustains pedal feel through extended high-load sessions. Stepping up to the Racing compound pushes the friction material’s operating window higher still, matching brake performance to the demands that the A45’s 360-plus bhp and AWD traction put on a front axle, while braided lines firm the pedal under load.
About the Hollow Front Brake Kit
This series applies a forged hollow-body caliper, the standard baseline, to a matched front-axle brake kit, with two-piece floating discs that reduce rotating mass while retaining the structural integrity needed to absorb the deceleration loads of a car in the A45’s weight and power class. For repeated high-speed lapping there is an optional Hollow Racing upgrade, with the dust cover removed, a 1000C rating, and a two-year warranty. Pad selection spans three compounds: Street is the quiet, low-dust default for road use and general spirited driving; Sport increases initial bite and sustained response for faster roads without the heat demands of a full circuit session; Racing runs hotter and harder, built for repeated high-speed stops without the friction material losing consistency across a day’s lapping. Caliper colour, no-cost in Red, Yellow, Gold, Black, and Anodized Black, with a custom Pantone match for £150, premium polished-forged finishes in Titanium, Polished Gold, and Polished Silver, and candy finishes in Teal, Blue, Red, and Orange, is specified when you order, covering the full range of A45 colour schemes and wheel finishes. Discs come drilled or slotted at the same price, and centre bells can be specified two-tone or titanium.
Fitment for the Mercedes Benz A Class W176 A45 4WD (2013-2018)
This kit covers the W176 A Class in A45 AMG 4WD specification across the complete production run from 2013 to 2018, taking in both pre-facelift and post-facelift builds. The chassis code is stamped on the VIN plate in the driver’s door jamb; W176 confirms correct application for this brake kit.

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.
