You need to go check out an autocross or track day near you. Almost all the properly set up cars, whether FWD, AWD, or RWD, will run a square setup. Running a staggered setup on a car with a balanced or front biased weight distribution and then trying to tune that to balance out the handling is not going to work well and is a butt backwards way of doing things. You should fit as wide tires to the front as is possible with your setup before going staggered. Standard RWD street cars with engines in the front come with staggered wheels for two reasons. First is to look cool, and second is to bias the handling towards understeer. Race cars go staggered because most have engines in the rear, wider in the front is simply not possible, and/or they are making obscene amounts of power and adding more rear traction to lay it down is a more important concern. What sort of suspension work? How balanced was the handling? Also "all spec'd for track runs" and 21" rear wheels on a 98-2002 Camaro doesn't really add up. Those are some monstrous wheels for that car.
