I have used to the greens on a few cars and Phil is running them on his, both as n/a and turbo, and yes they take a min or two to warm up but after that first brake, usually the end of the road, they are spot on. The GT has mintex fast road pads on it at the minute, though about to be changed, and they were good, probably every bit as good as the green stuff, but a lot more dust off them. Always thought red were just track use Mark
