These were on my buddy's Evora GT for just 800 miles and NO track time. Street only. I don't feel an edge at all and there is absolutely no warping. Very minimal wear on these rotors. Great rotating/unsprung weight savings! See photos! He is selling these because he is selling his Evora GT.
These are the semi-float version.
This will ship in 2 separate boxes to save on shipping. I get great rates from UPS; over 50% off retail.

These 2-Piece rotors combine the advantages of weight savings and rapid heat dissipation to provide a rotor superior to stock while preventing warping and extending component life. The reduction in rotational inertia allows for quicker acceleration, decreased braking distances, and more responsive handling.
Saves weight!
Slotted Disc: Segmented slot pattern for improved pad grip and pedal feel. Cleans away debris between pad and disc. Minimize warpage and brake fade resistance. Ensures maximum heat and gas dissipation.
Developed with the same parameters as the Original Equipment (OE) specifications in both quality and finish, Rotora®’s direct replacement brake discs are assured to meet and exceed all vehicle manufacturers’ specifications and tolerances under the worldwide ISO 9001 quality standards. CNC machined and balanced for optimum performance, Rotora®’s brake discs feature special segmented slot, or drill & slot pattern which is applied to the disc’s front and back surfaces to ensure maximum heat and gas dissipation for greater stopping power and minimize warping and cracking caused by repeated, high stress, high temperature braking. With an anti-corrosion zinc plating finish as an added protective layer to reduce corrosion and prolong disc life, Rotora®’s brake disc quality guarantees top performance and longer durability.

- Mill balanced to eliminate disc vibrations.
- Uniform thickness and finish of braking surface to ensure improved pad to disc fitment.
- Precise tolerance to ensure correct run-out
