I found this chart that is helpful. It's at the bottom of the page at the link.

Rear tire section..........Larger.....................Smalle r
Front wheel width........Narrower..................Wider
Rear wheel width.........Wider......................Narrower
Front wheel camber......More positive...........More negative
Rear wheel camber.......More negative...........More positive
Front springs...............Stiffer..................... Softer
Rear springs................Softer..................... Stiffer
Front sway bar............Thicker/stiffer..........Thinner/softer
Rear sway bar.............Thinner/softer..........Thicker/stiffer
Weight distribution.......More forward............More rearward
Front aerodynamics......More downforce........Less downforce
Rear aerodynamics.......Less downforce.........More downforce

I guess one issue is running conventional geometry with a neutral weight biased car. It would tend to over-steer. Plus the wider tires. I also understand with less caster a car will steer easier. Something to think about if you have no power steering.
