Wow I like you car...I from Wisconsin..Regarding your brake question...If you not tracking it the factory brake's are fine for hauling it down. On the track they will last for about 20 mins on Road America and then start to fade over the next 3 laps. I use no boil brake fluid and ceramic pads and drilled rotors.The only reason I'm changing them is he see's some hard ass braking on a track days....I've had the brembos and 18' wheels for 2 years now and still haven't done it cuz I almost never drive for 20 min on track. I have a Maserati GT and it handle's most of my track days now. Mostly cuz the seat's in the caddy are just not up to the job. After a day out I feel like I've been at the gym all day...and don't even get me started on the steering wheel...but the reality is he dosn't belong there ... But it's just to much fun driving it flat out and to see the look on the face of the guy with the V trying to figure out how that V6 can post "almost" the same time.
