Caliper render for this kit:
Close to two tonnes of rear-wheel-drive grand touring car, the M156-powered CLS 63 AMG places a disproportionate demand on its front axle every time 507bhp of naturally aspirated V8 gets used hard and the brakes must recover the speed. The factory AMG hardware handles road work confidently enough, but sustained use, club trackdays, Nurburgring tourist laps, or serious fast-road sessions on the kind of roads this car was designed for, will eventually probe its thermal limits.
The XYZ Racing front brake kit addresses the front axle directly: a pair of larger calipers and discs, a three-compound pad system and a full range of caliper finishes for CLS 63 AMG owners across the spectrum from road-biased daily use to dedicated circuit sessions. You set the specification when you order from the options above.
What this brake kit does for your 2004-2010 Mercedes Benz CLS 63 AMG C219
On a platform approaching 1,900kg, kinetic energy builds quickly and the front brakes carry the greatest share of deceleration load. The two-piece floating disc reduces unsprung and rotating mass at the front axle, while its hollow-vane construction vents air through the rotor body to improve heat dissipation and maintain more consistent pedal feel through the repeated hard stops that road-spec discs struggle to manage once heat-saturated.
Three pad compounds, Street for quiet, low-dust road use, Sport for fast-road running with occasional track sessions, and Racing for circuit environments, let you match friction chemistry to actual use rather than accepting a middle ground that serves neither mode well. Discs are available drilled or slotted at the same price.
About the XYZ Racing Front Brake Kit
The two-piece floating disc reduces mass in sections of the rotor assembly that carry rotational weight without contributing to the swept face, targeting thermal response and initial bite. On a rear-wheel-drive GT in this weight bracket, reduced rotating mass at the front axle also benefits steering feel through direction changes, less inertia for the suspension and steering geometry to manage each time the car is loaded laterally after braking. The kit is front-position specific, developed around the C219 AMG hub and caliper mounting geometry, with a hollow-body forged caliper as standard and braided lines for a firm pedal.
Three pad grades, Street, Sport and Racing, are selectable at order. Included caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with Custom Color matching any Pantone for 150 pounds. Premium polished-forged finishes cover Titanium, Polished Gold and Polished Silver, and the candy range adds Candy Teal, Candy Blue, Candy Red and Candy Orange. Centre bells can be two-tone in five anodized colours or titanium, and the optional Hollow Racing caliper, rated to 1000C with no dust cover and a two-year warranty, suits serious track use.

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.
