I think I'll get a set of Pacesetter headers and probably a Flowmaster catback setup for my Firebird. My buddy runs NitroPlate, THE exhaust coating company, so I'm going to have them coat the stuff. I was thinking about getting some sort of high flow cat, but I can't find the sort of information on them I'd like. I have a junk yard buddy trying to score a 3.73 posi for me.
I know EXACTLY what you mean about inclines. My Firebird was a year old when I bought it, and it had the ground effects crap on the front. With all the inclined driveways with gutters like tank traps around here, the front of the car looked like crap in 6 months, with big yellow scrapes showing through the black. I took the ground effects air dam off the front. Now I have a Trans Am front bumper cover without the air dam, since my wife decided to drive under the back of a Ford Exploder and do $2500 worth of damage. The damned thing is NOT lowered at all, and it still drags everywhere. I'd LIKE to lower it an inch and a half with a set of Eibach springs, and really set the suspension up for SCCA events, but I can't drive it on the road around here if I do. I lust after the springs, a set of Bilstiens, a new set of sway bars, and a set of urethane bushings. That'd really make the 16 x 9.5 Corvette wheels and 265/50/16 Falkens work well. I guess I'll have to leave it alone and work on my Corvair Corsa if I want to play SCCA racer.
