Yea, just a fyi, that heat video is misleading. These caliper covers were tested by a magazine and found the claim to be false and the explanation was very clear and made sense. They did the same test, got about the same results, but think, the covers are aluminum, which cools easily, and sit off the calipers. Now, they did another test, checked the temp of one uncovered caliper, then jacked up the car, took off a wheel with a caliper cover which took them about a minute then took of the cover and temp checked, it was 8 degrees(if I remember correctly) warmer than the uncovered caliper a minute before. That is not what you want. It is restricting air flow past your calipers, there is a reason they are not used by any manufacturer of brake components.
