Thanks for the comment of having brake caliper cover will over heat my brakes. However, I travel to las vegas recently with my car and nothing happen. I also used them on my other car. I've known MPG for long time now. MGP Caliper Covers demonstrate how caliper heat can be reduced by 25 to 50 degrees using Caliper Covers, improving braking performance by reducing brake fade. The covers are made of aerospace aluminum and act as a heat sink, dissipating the heat from the caliper more efficiently. The curvature of the cover also helps direct air to cool the caliper.
