Posted on another thread but I wanted to get the word out:
I just tested out the Paragon rotors for my Model 3. These rotors look nice on the street, but perform like garbage when they get hot. I installed these rotors this past weekend and began the bed-in process for the pads/rotors. When the rotors got up to track temperatures, the brakes began to grind in the front and rub in the back. I worked with Paragon the whole week to help diagnose the problem. They kept on insisting it was my calipers, pads, fitment, etc. I KNOW I INSTALLED THIS KIT RIGHT, but I still tore everything apart again and verified everything was functioning properly. It is the identical to the install process of the MPP rotors. And I doubted my $800 Endless pads were the cause of the problem, I just bought them new on 10/7.
When I got back home after some hard driving, I discovered that the rotors were expanding so much under high heat that they no longer cleared the inner caliper. The rotors were shaving off my inner caliper and damaging them!!! See attached pictures.
I could maybe recommend these rotors as an aesthetic upgrade for the street, but they completely fail for performance driving. Having grinding/shuttering brakes while in race conditions is not only unacceptable, but just plain unsafe. Definitely will be stepping into the MPP BBK rotors once I get my coins from Paragon.
I wasted my time, energy, and money on these and can only be disappointed in myself for trying to save a few hundred bucks. I learned my first and last lesson with budget performance parts, never again. Buy quality, either MPP or get a full on BBK.
