Earlier this year, we talked about the sinkhole developed beneath the National Corvette Museum. Eight classic Corvettes fell into a 40-foot-wide, 30-foot-deep sinkhole and GM said that only three of the eight vehicles will be restored. The lucky models were a 2009 Chevrolet Corvette ZR1 prototype (the Blue Devil), a 1962 Corvette and the one-millionth Corvette, a 1962 convertible.
The first model to be restored was the ZR1, nicknamed the Blue Devil, one of the two show cars used by Chevrolet to introduce the all-new Corvette ZR1 in January 2008.
The vehicle was actually loaned from Chevrolet to the National Corvette Museum and the damage included cracked carbon fiber ground effects, a broken passenger-side rocker panel, damaged passenger front fender, cracked windshield, window glass and passenger headlamp assembly.
Moreover, the damages also included bet rear control arms on the driver’s side as well as cracked oil lines to the supercharged LS9 engine’s dry-sump oiling system.
Chevrolet Corvette ZR1 and the Corvette Z06 have similar suspensions and aluminium intensive chassis materials. The only difference is that the ZR1’s tuned suspension was designed to enhance the Corvette’s wide tyres at the front and rear.
ZR1’s Magnetic Selective Ride Control unit is also specifically tuned for it to provide superior cornering grip and excellent ride quality. With this system, Chevrolet ZR1’s rear axle also stays firm during launch for smoother acceleration. The ZR1-tuned Magnetic Selective Ride Control also secures the movement of the axle especially on tight corners and bumpy roads.
On the other hand, the ZR1’s engine output is equally important to the braking system. Due to this, the Chevrolet Corvette ZR1 is equipped with heat and wear resistant carbon-ceramic brake rotors.
The ZR1’s vented and cross-drilled rotors are 394mm (for the front) and 380mm (for the rear). These sizes only prove that the Chevrolet Corvette ZR1 has the largest carbon-ceramic rotors than any other vehicles produced. Basically, the rotor is made with carbon, ceramic and silicon products. These types of materials are usually free of corrosion and are enough to last for many years.
The highly advanced rotors are equipped with 4-piston rear calipers and 6-piston calipers for the front. Each brake caliper is painted in blue, a colour that is developed exclusively by Chevrolet for the ZR1 model.
Apparently, the front pads are significantly larger than the Z06’s 70-sq.cm single pad design. And finally, the brakes are visibly seen through the 20-spoke alloy wheels measuring 20-inch and 19-inch for the front and rear. These wheels are painted in Sterling Silver or chrome and are fitted with ZR1’s P335/25ZR20 and P285/30ZR19 Michelin Pilot 2 tyres.
