Since my car has disc brakes, it is supposed to have slotted hubcaps. I bought a set last year, but had never got around to putting them on. A few weeks ago I was coming back from a car cruise. It was a 95 degree day and a very hilly and windy drive, so I was using my brakes alot. By the time I got home, I could smell them burning. The front hubcaps were so hot, I couldn't even touch them.
I finally got around to transferring the medallions and put the two best slotted ones on, just the front for now, and it makes a huge difference. No more over-heated brakes. I guess those GM engineers knew what they were doing. The only draw back is now the brake dust comes out of the hubcap and goes all over the whitewall. Pics below of slotted, vs non-slotted.
