Well, my budget's less than stellar for wheels and the like...no $1000+ each Volks or anything, let's get that out of the way. =) The Kousei 17s from Tire Rack are 14.1 lbs each and the Kazera 16s are 16.5. By lightweight I pretty much mean 'don't crush my acceleration with 3 inches of chrome plating and a rim deep enough to put dollar bills in lengthwise'.
Hah...pictures, eh? You got it.

New seat covered,

End result: Looks the same. I can take corners 20+ mph faster, feel the road better but the harshness less, sit lower and thereby see more sky, and be vastly more comfortable. Yay!
