Massive wheels

The 2009 Corvette ZR1 will have 19-inch alloy wheels in the front and 20-inch wheels in the back. It will run on high-performance Michelin tires created specifically for this car.

The brakes use carbon-ceramic rotors that weigh less than metal rotors and, according to GM, should not require replacement for the life of the car when used in normal driving.

The brake calipers are painted a blue color that is specific to the ZR1.
