Asking a couple questions-will my A body corner?

ARE 'Ansen' rims are relatively low cost, strong, and wiegh less than the same size 'ralley' steel rims. You'll have look at some different brands (like Toyo) for good 15" tires, and you're not going to find the ultra-performance summer tires in 60 series. Tirerack is a good place to look online, but remember there are brands and models they don't carry. No Hekkappalittas, no bias ply Hoosiers for a couple of extreme examples.

Decide on your tires and wheels and build the rest of the program to match them. Generally I'd be encouraging front sway bar, good alignment, good shocks like Bilstein and the rest depends on its current condition and the tires and terrain. Anything you can do to reduce weight on the nose and get hieght down (unless you are off roading) will be a plus.
