I was literally at the track the day after I got mine. Modern cars don't need a break in. Oil analysis came back with lower than average metals in the oil.
Here's another oil analysis. My engine is all stock, and about 200 track miles on this oil. I'm going to put Castrol 5w40 (BMW LL01) in it for my next few track events and then send in a sample again. Seems like this engine might not care what kind of oil you put in it.
That's what I'm saying. You won't find anything that less dusty than stock pads. Where do you think all the friction material goes when you wear down pads of this size?
I'm literally at the track every weekend. I need some cheap light wheels that I won't feel bad about bending. I don't think they'll fit over supra brakes if they don't fit over STI brakes.
