They are supposed to be for more 'aggressive' street driving, but I agree that prob doesn't mean much.

I have come across a few people who have auto-x'd them and had good things to say about them. They seem to work well for light track use (auto-x) but would fall apart under any prolonged heavy track use. For just a street pad though they seem to have lower dust, noise, better stopping power then OEM pads and, in my case, are less then half the price of OEM. Either way, I will know soon enough.
