These carbon fiber rotor hats are going to be so good. GT500, GT350, and Dark Horse compatible. These have several amazing elements outside of the aesthetic benefit of hiding those tired and dirty aluminum hats.
.
In terms of design and engineering, I will add some background. With all carbon production longevity lies in the materials. Using an appropriate high temperature resin and UV resistant clear coat will ensure no issues with yellowing. One of the great properties of carbon is that it does not hold heat. This is demonstrated with carbon ceramic rotors, and why you need to get heat into them before use.
.
Additional design elements include slotted vents and varied mountains/valleys. This is done to create turbulence inside the wheel, and move stale hot air. The area within the hub should see increased air movement, and evacuate air though the slotted vents.
It should be noted that the vanes connecting the hub to the rotor limit the amount of heat transfer that the hub actually sees. After testing that area with pyrometers it is well under the limit of the resin/UV protective clear coat. Our carbon fiber python hood vents actually see hotter temps being right above the blower and absorbing atmospheric heat from the sun. Those have seen several years of use without yellowing.
More installed pics below, and the live link with pricing.

. The OP post says it’s a “rotor hat” so I thought it was, you know, a rotor hat. Didn’t realize it was just ricer crap. Sorry for the dumb question and thanks for making me dig in a little more.
