Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2003-2012 Mercedes-AMG SL65 / SL63 / SL55 (R230) Carbon Ceramic Brake Kit — OEM-Size Replacement
The R230 SL65, SL63, and SL55 AMG put heavy GT weight, high engine torque, and large fixed AMG calipers into a chassis that can overheat or consume iron rotors during repeated high-speed braking. This StopFlex OEM-size replacement kit keeps the correct AMG rotor references—390mm front / 360mm rear for SL65 and SL63 applications, and 360mm front / 330mm rear for SL55 applications—while changing the friction ring to carbon ceramic for lower dust, lower rotating mass, and better heat stability. The kit includes carbon-ceramic rotors, matched pads, hats, and floating hardware, so fitment is based on the exact trim and rotor size rather than a generic R230 listing.
- SL65 and SL63 fitment is built around the 390mm front and 360mm rear AMG rotor references used with the larger R230 brake package.
- SL55 fitment is limited to the 360mm front and 330mm rear rotor references listed for this page; cars with other AMG brake packages must be verified before ordering.
- Carbon-ceramic rings reduce brake dust on the R230’s open AMG wheels and remove rotating mass from the front axle where steering feel and damper control are most sensitive.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Mercedes-AMG SL65 / SL63 / SL55 (R230) |
| Model years | 2003-2012 |
| Front rotor reference | SL65/SL63: 390mm; SL55: 360mm |
| Rear rotor reference | SL65/SL63: 360mm; SL55: 330mm |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 20" (for the 390 mm rotor) |
For OEM replacement orders, StopFlex builds around the factory rotor specification shown for this vehicle. Front floating-caliper setups require manual review before production. If the car uses aftermarket calipers such as Brembo, AP Racing, Alcon, or Wilwood, the order can still be built, but the exact caliper model, pad shape, and rotor dimensions must be confirmed before production.
This setup uses a 390 mm rotor, so the minimum wheel size is 20". Wheels under 20" will not clear the caliper and rotor, and spoke profile and offset affect clearance too — confirm your exact wheels before ordering.
Why StopFlex CCB
Lower Unsprung Mass
StopFlex carbon-ceramic rotors are engineered to reduce rotor mass versus comparable iron discs, helping the suspension react cleaner and the steering feel more precise.
High-Temperature Stability
The carbon-silicon-carbide matrix is built for stable braking behavior at temperatures that can push iron rotors into heavy fade.
Rust-Free Rotor Surface
Carbon ceramic does not form orange flash rust after rain, washing, or storage, keeping the visible rotor face cleaner behind open wheels.
Long Street-Service Potential
In normal road use with matched pads and proper bedding, StopFlex CCB rotors are designed for far longer service life than typical iron replacement rotors.
Low Visible Dust
When paired with matched StopFlex pads, the system produces very low visible brake dust compared with conventional iron rotor and pad combinations.
Premium Ceramic-Glaze Appearance
StopFlex's proprietary coating creates a bright, high-end ceramic-glaze finish with subtle glaze texture and a more premium visual character behind open wheels.
Street-Usable Cold Bite
Street Spec and Track-Day Spec rotors are designed for normal first-stop road use, including cold-weather operation. Motorsport Spec is the competition-focused exception.
Continuous Fiber Reinforcement
Long-fiber carbon ceramic construction improves structural strength and thermal durability versus chopped-fiber approaches.
Custom Rotor Hat Color
Every StopFlex OEM replacement order can be built with a custom rotor hat color, giving the carbon ceramic rotor package a cleaner match with the wheel, body color, and overall build style.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat can still soak into pads, fluid, seals, calipers, wheels, and nearby components. For long track sessions, mountain descents, or sustained aggressive driving, brake cooling and high-temperature fluid are still recommended.
Street / Track-Day / Motorsport Rotor Options
Street Spec
Ceramic coating, cross-drilled face, and large cooling channels.
Best for daily driving and premium street builds that need clean cold bite, low dust, corrosion-free appearance, and long service life.
Track-Day Spec
Ceramic coating, blank face, and honeycomb cooling channels.
Best for fast-road and track-day use where repeated braking stability matters more than maximum visual drilling style.
Motorsport Spec
Uncoated blank face with honeycomb cooling channels.
Best for race-focused builds that run competition pads, high-temperature fluid, cooling strategy, and a proper warm-up window. Not the default street choice.

FAQ
Will this kit fit every 2003-2012 R230 AMG SL?
No. This page is limited to Mercedes-AMG SL65, SL63, and SL55 R230 cars using the rotor sizes listed here: 390mm front / 360mm rear for SL65 and SL63, or 360mm front / 330mm rear for SL55. Confirm your current rotor diameter and caliper package before ordering.
Do I need different wheels or calipers?
This is an OEM-size replacement kit, so it is designed around the factory AMG caliper position and rotor diameter for the listed brake setup. Wheel clearance must still match the original brake package on the car; if your R230 has non-factory wheels or a swapped brake package, verify spoke and barrel clearance first.
Will the parking brake still work?
Yes, when ordered for the correct R230 rear rotor specification, the supplied hats are built to retain the factory rear parking-brake arrangement. This chassis does not use the later electronic parking brake setup found on newer Mercedes platforms.
Why switch from iron rotors to carbon ceramic on this car?
On a heavy SL65, SL63, or SL55, carbon ceramic rotors help control repeated high-speed heat, cut visible brake dust, and reduce unsprung rotating weight compared with iron discs. They are best for owners who want an OEM-size brake package with cleaner wheels and more thermal margin, not a larger caliper conversion.
