Fits Mercedes Benz CLA AMG 45 4WD C117 (2013-2019)

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.

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 — Mercedes Benz CLA AMG 45 4WD C117 (2013-2019) — 356 mm
356 mm

The CLA 45 AMG C117 carries its engine weight forward on the MFA platform, and at the end of a long straight it is the front axle that absorbs the energy, repeatedly, with no recovery time between corners on track. The OEM AMG front hardware is sized for public roads: competent, but never intended for the thermal punishment that follows when 360-plus bhp of turbocharged four arrives at the same braking marker half a dozen times in a session. The XYZ Racing front brake kit closes that gap with a pair of larger front calipers and discs built for the load.

This is a front-axle kit: two calipers and two discs for the leading wheels, where the C117 does the bulk of its braking. Three pad compounds span daily driving through to dedicated circuit work, and the included caliper colours run from understated to vivid. You set the full specification when you order from the options above.

What this brake kit does for your 2013-2019 Mercedes Benz CLA AMG 45 4WD C117

The C117’s front axle carries a disproportionate share of the car’s braking load, a consequence of the forward weight bias inherent in the transverse MFA layout. A larger front disc adds swept area, which dissipates heat faster and keeps the friction material in its effective temperature range deeper into a session. Pedal response stays firm and linear rather than going long as the standard discs run out of thermal capacity.

Each disc uses a hollow-vane construction that draws air through the rotor body during rotation, carrying heat away from the friction face more efficiently than a solid casting. The lighter rotating assembly also trims unsprung and rotating mass at the front corners, which the C117’s steering and suspension feel at turn-in. Pick the Street compound for a quiet, low-dust road car, Sport when you mix fast road with the occasional track day, or Racing when the CLA spends real time at a circuit.

About the XYZ Racing front brake kit

The caliper is a hollow-body forged unit as standard, paired with two-piece floating discs that let the rotor expand and contract under heat without distorting. Discs come drilled or slotted at the same price, so you choose on looks and feel. Braided lines firm up the pedal by removing the flex of rubber hoses under pressure.

Included caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost. If you want an exact shade, Custom Color matches any Pantone for an additional 150 pounds. Premium polished-forged finishes are offered in Titanium, Polished Gold and Polished Silver, and the candy range covers Candy Teal, Candy Blue, Candy Red and Candy Orange. Centre bells can be specified in two-tone across five anodized colours, or in titanium. For owners running the CLA hard on circuit, the optional Hollow Racing caliper upgrade deletes the dust cover, is rated to 1000C and carries a two-year warranty.

Fitment for the Mercedes Benz CLA AMG 45 4WD C117 (2013-2019)

This kit is designed specifically for the Mercedes Benz CLA AMG 45 4WD on the C117 platform, covering 2013 to 2019. That span includes both the original 360 bhp specification and the 381 bhp facelift. Confirm your chassis code is C117 before ordering. The kit does not cross to the A45 AMG W176, which shares the MFA architecture but uses different front-axle packaging, nor to the later C118 CLA generation introduced in 2019.

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.
