I decided to give the Carbotech XP8 a try on the front of my GT350. I enjoy track days and although the factory pads are good, wanted to see if there really was a difference. Pad swap was easy, had the rotors machined so I had a clean surface to bed. Went through he recommended bedding process. However had to use the street versus track as annotated in the instructions. After the proper cycling, I made a couple stops from 100mph and damn near broke a rib! Crazy bite. So far I'm really happy but will follow up after the next Track Night in America at my local track. Only draw back is that they squeal when they are cold. Oh well. Next project: Vorshlag Camber plates.
