Well, having done this exact thing to my car as well (minus painting the calipers) I can say they are much better than stock on the track. On the stock brakes/fluid (mistake) I boiled my clutch fluid one session, then my brake fluid around the calipers, in another, giving me very little in braking force coming off the main straight (luckily there was a runoff) and I was able to steer into a gap in the concrete barrier... anyway. Experienced almost no fade after the upgrade and only used about half the front pads in 5 hours of track time. The only negative I have to report is that I still managed to slightly warp my DBA 5000 series front rotors, even tho the thermal paint on the rotors says they stayed well within optimal operating temp. I'm not entirely sure how it happened as I noticed it 1st when I was braking for pit lane after a session on the second day. I had them machined lightly and problem solved (or rather bandaided). My only guess is that I actually cooled the rotors too suddenly on my cooldown lap.
Enjoy your brakes, they wont fail you on the track and they are entertaining on the street as well.
Edit: Noticed you got the Sport rather then Race package, you'll have to let us know how those rotors do on track
Dont forget to change your clutch fluid, I put Motul 600 in mine. And I agree, Scott is great.
