Is this a complete brake rotor or just a replacement ring?

This is a replacement disc ring for a 2-piece floating rotor system. You will need the existing rotor hub to install this ring.

What is the benefit of the swept grooved finish?

The swept grooved finish helps to degas the rotor surface and keep it clean from dust and pad material. This can lead to more consistent braking performance, especially during repeated hard stops.

How many vanes does this rotor have and what do they do?

This rotor ring features 48 curved vanes. These vanes are designed to help move air through the rotor, which aids in dissipating heat generated during braking.
