I use the stoptech performance pads as well. For the price they are hard to beat.
I'm looking for something a little better now that I want to do some track days. I like the carbotech AX6 I just don't know if they would be good enough for a track day too. The XP8's and XP10's would be good but they sure are expensive!
Why are WRX brakes almost the same price as STi brembo pads?!
