EBC Floating Disc Description:

Floating EBC brake discs are lightweight replacements for original OEM units. Precision made in the United Kingdom to fine tolerances for durability and perfectly balanced, eliminating vibration. EBC Brake rotors are assembled with our patented Square Drive button system further extending rotor life and braking performance. Floating MC rotors feature mill hard stainless steel high friction rotor blades for maximum brake effect and are the direct size for size replacements for OEM rotors.

Both designs are also true fully floating units, offering more inside to outside float tolerance than any other rotor on the planet. You should not be able to move either the buttons or rotor blades from side to side, if you can, it is highly likely that pad “Knock Back” will occur and you will end up with spongy brakes. Float means outside to inside heat expansion ability.
