I like the 19's. Great compromise for the guys who think 20's look too big and the 18's just aren't big enough. If it were my money, I'd stagger them. 19x8.5 up front and 19x10.5 out back. That'd look sick!!!
I've never been a fan of wide wheels up front. The 9" wheels are doable, but you'll get a little "hunting" or wandering back and forth when driving down the highway. My friends '03 Cobra used to find every little dip and crack on the road. It got really tiresome after a while. And they don't really handle any better than a set of 8" or 8.5" wheels IMO.
