What makes this rotor different from a solid rotor?

The three-piece floating design isolates heat and movement, reducing warping and noise while the helical ring prevents looseness over time.

Do I need to use Lyndall brake pads with this rotor?

Lyndall backs this rotor with a lifetime warranty when used with Lyndall premium organic brake pads exclusively.
