If anyone has seen my video driving around where I live, then you can understand what kind of torture I put my brakes through on a daily basis. In that video, I was rolling stock brakes, and what I did not video was the smoke pouring out of the front wheels after I stopped filming. I literally thought my brakes were on fire.
After I swapped in the drilled/slotted, I have never even smelled my brakes or seen any signs over "overheat". My pads are wearing better than they ever did on stock rotors. As far as stopping distance, I can't say that it improved much. If so, it's minimal over stock.
I have heard people talking about cracking and such, but I still think that it's probably from those Ebay kits.
Kinda goofy but you get the point.
I REALLY need to redo that video, now that the truck has more power (as well as that sweet whine noise. Lol).
