Caliper render for this kit:

The W209 CLK 200’s front axle carries the weight of a 1.8-litre Kompressor four-cylinder ahead of a long, raked bonnet, a nose-heavy balance that concentrates more mass over the front wheels than the coupe’s proportions imply. Standard brakes manage daily use competently, but ask more of them on a track morning or a sustained run through the Peak District and the entry-level specification announces itself clearly.
This XYZ Racing front brake kit replaces that setup with a pair of larger calipers and discs for the two leading wheels, plus configurable pad compounds covering refreshed daily-driver feel through to full circuit sessions. You select compound and caliper finish when you order from the options above.
What this brake kit does for your 2003-2009 Mercedes Benz CLK 200 W209
The two-piece floating discs shed rotating and unsprung mass from the front axle, and the reduction registers at turn-in before you touch the pedal: less mass means the front wheels track surface changes with greater accuracy, sharpening the steering feel the standard CLK 200 blunts on demanding surfaces. Under braking, the hollow-vane disc geometry vents air through the rotor body to extract heat more aggressively than a conventional vented rotor, cutting the fade that accumulates across successive hard stops. That is a genuine issue on track days, where the Kompressor’s weight relative to its output means you are braking frequently rather than occasionally.
The Sport compound raises the operating temperature window for spirited fast-road use; the Racing compound extends it further for circuit sessions where a road pad would begin softening mid-session. Street remains the quiet, low-dust default for everyday driving. Discs are available drilled or slotted at the same price.
About the XYZ Racing Front Brake Kit
The kit is built around two-piece floating discs that remove material between the faces while preserving the rigidity demanded under hard front-axle braking. The geometry promotes heat dissipation at lower mass, without the fatigue-cracking risk that aggressive cross-drilling can develop under sustained circuit use, and the calipers are hollow-body forged as standard, fed by braided lines for a firm pedal.
Three pad compounds cover distinct operating ranges: Street for quiet low-dust road use, Sport for spirited fast-road conditions, and Racing for circuit work. 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 go 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, is there for serious track use.
Fitment for the Mercedes Benz CLK 200 W209 (2003-2009)
Built for the W209-platform CLK 200, this front kit covers the full 2003 to 2009 production run across both coupe and cabriolet body styles. Fitment applies to the CLK 200 designation within the W209 range. If your car carries a different engine variant or belongs to a different CLK generation, confirm the correct application before ordering. Front axle only.

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.
