I'm an odd case on wheels. I really needed the extra clearance of the 15"s for brake ducting and cooling. 13" wheels aren't too hard to find in reasonable weights, it's the 14"s that I think people have trouble with the most. And the Volk 15s I bought were actually ligther than my original set of 13" Panasports at 10 lbs.

Less unsprung mass, lighter tires, lower cg without changing geometry, lower rotational interia, improved brake 'leverage' (this one especially catches my eye in your case) on the track surface. Is a 225 tire too narrow for your needs?

Look in to Spin Werks - formerly Circle Racing Wheels.
