You'll have a tough time finding aftermarket wheels as light as the stock 15 x 7 tri-spoke alloys that came on my car from the factory and that's why I still run them, even though I've never been happy with them from an aesthetic standpoint.
I keep them because lower rotational mass equals less torque required to get them turning, less swept brake area to stop them, and they represent less unsprung weight for the suspension to overcome. I'll keep running them as long as Pirelli keep making the sticky P235/60 15 tires I'm running, which are the same as I ran on my Porsche 924S that I had prior to the Mustang -a car which also had 15" wheels. I might ditch them sooner if I can find some 17" wheels that aren't much heavier. So far, no joy.
I do run spacers between the wheels and the brakes to kind of help improve the look and widen the stance for improved handling.
If I had V8 torque, I slap a set of FR 500 style wheels on, but with my engine only putting out 192 ft/lb to the rear wheels, I don't personally think I have enough spare torque to squander in trying to spin heavy wheels.
