Clifton, thanks for the tips.
I know the brake thing, on the Camaro I definately would get brake fad (duh), but on the Z I dont yet have enough tire, to handle even my current brakes. I need a bias valve because the rear is TOO POWERFULL, they slide and there is no way I can stand on my brakes, steel lines, 195/60 -15x7" setup, 300 treadwear, not enough grip. Someone else with 225 wide Kumho V700s said he could stand on the brakes with no problem, but those tires blown mine away.
400+ HP would be crazy power, was thinking of a T3/4 hybrid, part of the reason is I need to start with something that will fit the stock manifold... Long term, sure more power and monsterous wheel/tires would be great, but also I dont want to put myself in a car that is faster than me, I made that mistake with the Camaro jumping to nearly 500 HP, and it really cripples a driver with my experience level. People who haven't been on a track will likely never understand that until they do, if you want to learn how to be fast, then put your butt in a slow car, and you WILL learn to carry the car around the track, because any screw up will hurt your times in a big way, and it will teach you the line. Otherwise, I just end up doing a drag race, with some crappy cornering between my next WOT run...
