I find that the stock pads are inadequate, both for street and track. They get way too hot on a track and can eventually warp the rotors. On the street at lower speeds they are too grabby and hard to modulate.

That being said, the rotors and calipers are more than up to the task, even for hard-lapping on long and short tracks. Try changing the pads. I run PFC 01s for track days and they stop the car like an anchor. For the street the PFC Z are amazing (and give off less dust than OEM). I used to track with the Z pads, but as I got faster, they weren't quite what I needed. The only negative with the Zs on the road is that there is a low-frequency thrum that you can hear as you brake. I can live with it, but it's noticeable. I have just installed EBC Greenstuff pads for the street in the last 50 kms, so we'll see how those are.
