2009 Chevrolet Corvette ZR1
To put the extra power to the ground the ZR1 uses a stronger 6 speed manual transmission featuring a twin-disc clutch, As the term implies, the twin-disc clutch system employs a pair of discs, which spreads out the engine’s torque load over a wider area. This enables tremendous clamping power when the clutch is engaged. It also dissipates heat better and extends the clutch life.
With the added power, it's also important to be able to stop quicker so the ZR1 is the first Corvette to feature Carbon Ceramic brakes which were previously only found in high priced exotics. Of course its $100,000 price tag isn't cheap and you probably won't be seeing one everyday but relatively speaking it's still quite a bargain.
Unlike the Z06 which could be confused for a normal Corvette other than a few badges and different wheels, Chevy made sure no one will confuse the ZR1 for anything else. Most noticeable is the see through glass in the hood showcasing the supercharged beast in all its glory. ZR1 badges on the front fender and rear bumper will intimidate anyone even thinking about a red light challenge and once you're inside, the ZR1 logo is prominently displayed on the door sills, tach, and headrests.
A final major difference is the 20-spoke alloy rims that measure 19 inches in diameter in the front and 20 inches in the rear. They come standard with a bright, Sterling Silver paint finish and chrome versions are optional. The wheels are wrapped in Michelin Pilot Sport 2 tires developed specifically for the ZR1, measuring P285/30ZR19 in front and P335/25ZR20 in the rear.
