Fits Mercedes Benz SL 55 AMG R230 (2001-2012)

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 — Mercedes Benz SL 55 AMG R230 (2001-2012) — 330 mm
330 mm

The R230 SL 55 AMG was never a lightweight. At nearly 1,900kg with its supercharged M113K V8 sitting well ahead of the front axle, it carries more mass into every braking zone than most performance cars in its class, and the factory AMG setup, competent on the road, shows its limitations when braking loads accumulate. Repeated late-braking events, whether on a mountain descent or a circuit’s approach to a hairpin, generate the kind of heat that surfaces as increased pedal travel and a longer stopping distance.

The XYZ Racing front brake kit upgrades the front axle of the Mercedes Benz SL 55 AMG R230 directly, replacing the hardware that carries the greatest braking load at the end of a fast straight. It is a single-axle kit: a matched pair of front calipers and two-piece floating discs for the left and right corners. Three pad compounds mean the kit works across the full spread of use, from spirited touring to dedicated track sessions, without a hardware change between outings.

What this brake kit does for your 2001-2012 Mercedes Benz SL 55 AMG R230

The hollow-vane disc pulls heat away from the friction face more efficiently than a conventional vented casting, tightening the working temperature window even under repeated hard use. That matters on the R230: the ABC active suspension removes almost all body roll from the equation, so when the car reveals its mass it does so under braking rather than through cornering. A more consistent pedal translates directly into the confidence to brake later and more precisely, and the two-piece floating disc on its alloy centre bell trims unsprung and rotating mass so the front end settles faster between stops. Three pad compounds cover the range: Street for quiet, low-dust daily use, Sport for fast-road work with more bite and heat range, and Racing for sustained circuit sessions where thermal management is the priority. Braided stainless lines keep the pedal firm as the system heats, letting the conversion work visually inside the R230’s large-diameter front alloys as well as it works dynamically.

About the Front Brake Kit

The hollow-vane disc is what distinguishes this kit from a standard vented-disc upgrade: the internal geometry creates a direct air path through the rotor body, dissipating heat rather than trapping it within the vane structure. XYZ Racing specifies the kit across three pad compounds, Street, Sport and Racing, covering everything from low-dust daily use through to sustained circuit work. The forged caliper is hollow-bodied as standard, with painted finishes included at no extra cost in Red, Yellow, Gold, Black, or Anodized Black, and a Custom Color to any Pantone for £150. Polished-forged finishes run to Titanium, Polished Gold and Polished Silver, candy finishes to Teal, Blue, Red and Orange. Discs are drilled or slotted at the same price, two-tone centre bells come in five anodized colours or titanium, and a Hollow Racing upgrade is available for the track, dropping the dust cover, rated to 1000C with a two-year warranty. The front-only application keeps the upgrade focused on the axle that does the heavy lifting when a near-1,900kg grand tourer needs to shed speed in a hurry.

Fitment for the Mercedes Benz SL 55 AMG R230 (2001-2012)

This kit covers the Mercedes Benz SL 55 AMG in full R230 specification, from the 2001 model year through to the end of production in 2012. The R230 chassis code spans the complete production window for this generation of SL-Class in AMG 55 form. All build years within this range are included.

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.
