Product Code: MB-IRK-14

Features and Benefits:
  1. Front brake are over-sized to SL65 AMG (390x36) re-use stock caliper w/RB adapters (included in the kit)
  2. Massive rotating mass and unsprung weight reduction (see table below)
  3. Purchase this car kit will save you 10% than purchase front and rear separately
  4. Best value compared to all other BBK options - Complete car kit costs 15% less than Brembo's front only kit $4,699.20
Kit includes:
Rotor Weight Comparisons:


Size (mm) Wt (lbs) Size (mm) Wt (lbs)
OE One Piece 360x36 36 360x26 22.5
OE Two Piece 360x36 29 NA NA
RB Two Piece 390x36 28 360x26 16.3

Oversize to BS BBK yet you still can save huge 28 lbs for four corners.

Replacement Components:
Front Rotor Ring: D601-05-381
Rear Rotor Ring: D406-02-381

RB rotors are made of harder iron than OE rotors. Our rotors are most compatible with semi-metallic brake pads. We do not recommend the use of ceramic brake pads, which may cause vibration.

Rotor Material: Racing Formula Alloyed Gray Iron & Heat treated

These two-piece rotors were engineered to be the best stock replacement two-piece rotor on the performance market. This rotor is direct bolt-on, easy to install, no additional hardware needed. They can deliver consistent brake torque under extreme heat, session after session. When it comes to replacement - operating cost over the time will be lower than one-piece rotor. Our unique and patented rotor designs make our discs cooler and last longer:

  1. Convergent vane design

    The cooling vanes are of a convergent nozzle design, which increases airflow and turbulence and makes discs cooler. (Illustration #1)

  2. Center-mount design

    The center-mount flanges for hat mounting to the rotor ring have several benefits. (Illustration #2)
    • It allows the ring to be used on either side of the vehicle simply by mounting the hat on either side of the ring (unidirectional).
    • The stress load transferred from the ring to the hat is balanced.
    • Air inlets are widely open to both inboard and outboard sides of the rotor. More air suctions and even temperature on both sides of the disc surface.
    • Heat transfer from the disc surfaces to the hat is even and minimized by increasing the flange length and the airflow around the flanges.
    • Mounting flanges are on both friction surfaces ultimately provides excellent heat balance.
  3. True floating design

    Exclusive full floating design with 10.9 grade alloyed hardware. Hardware is DACRO coated and crimp locking. DACRO is highly corrosion resistant and provides a film for easier movement between the hat and rotor ring as disc expands and contracts and the crimp design provides positive engagement without rattling or torque loss at temperature.

  4. Iron sleeve insert
RB aluminum rotors hats are constructed of aluminum with an iron sleeve insert. This allows for significant weight savings while still preserving the use of the stock emergency brake. This design is only available through RB.

Installation Note (for installing new front RB adaptor):
Tools needed for install:
  • Breaker bar
  • Ratchet
  • M10 hex socket
OE caliper w/OE bracket.

Use M10 hex socket to remove M12 bolts and detach caliper from OE adaptor.
(This can be done with adoptor still attached to spindle/hub carrier)

OE adpator and M12 bolts.

RB adaptor and M12 bolts replacing OE setup.

Secure caliper to RB adaptor w/RB adaptor part number facing you (same direction as AMG logo) using RB M12 bolts.
