In terms of wheel finish, a bright silver paint coat is standard and a chrome version is optional.
The matching Michelin Pilot Sport 2 tires measure P285/30ZR19 in front and P335/25ZR20 in the rear. While Michelin's PS2 tires are offered on many vehicles, these were engineered specifically for the ZR1, GM says.
The car's braking system features Brembo carbon-ceramic rotors measuring 15.5 inches up front and 15 inches at the rear- the same units used on the Bugatti Veyron supercar. GM says the rotors are so durable they should not requiring replacement for the life of the vehicle.
Squeezing the discs are six-piston front calipers and four-piston rear calipers, painted in ZR1-exclusive blue.
