Aye, I know the feeling. Yesterday was the first run out with the new (2nd hand) front Brembos and I have to say, they were mucho better than my previous standard 4-pots. Not so much that they are more efficient, although they are, but they are more durable. On the last track day I warped and heat fractured my front disks, effectively trashing them in the space of a few laps, as I was running with the new power. I want more power too! Ha! Shameful is it not? I need to invest in an oil cooler first of all though.
