The new Ford Mustang Shelby GT350-R with the 5.0L flat plane crank has carbon fiber wheels. These are substantially lighter than even the non "R" aluminum versions.
The lighter wheels allowed the car to accelerate 1.1 seconds faster from 50-70 mph. This comes at a very steep price though. The front wheels are $3400 each, the rears are over 4 grand apiece!
