All that's left to turn that into a real track terror is modern low-profile performance tires. I need shocks and UCAs on my Duster (avatar pic) and I'll pretty much have the same setup as you, plus wheels and tires.
Yeah I had some 18" mustang wheels I ran at autocross a couple times but I don't like the look. I would go for some 17" or 18" wheels if I could decide on some that I like the look of. I almost went with some larger steelies since I like the look but am just using the 15" cop wheels with dog dish hubcaps until I make my mind up some day.
