What is the advantage of a two-piece floating rotor?

A two-piece floating rotor uses a separate iron friction ring and aluminum hat. This design helps manage heat buildup and reduces the risk of the rotor distorting or cracking under heavy track use.

Does this rotor come with mounting hardware?

This listing is for the rotor only. It is designed to be a direct replacement for the original rotor and uses the existing hardware for the hat and caliper mounting.

Can I use this rotor on a street-driven Porsche 991?

This Alcon Pro-System rotor is specifically designed for the Porsche 991 GT3 Cup model and track use. While it may physically fit other 991 models, it is not intended or recommended for street applications.
