Traction is provided by Michelin Pilot Sport Cup 2 R tires as part of the ZTK track package. For reference, the $174,995 (including destination) Corvette ZR1 produces 1,064 hp and has a top speed of 233 mph. For track driving, the $8,495 ZR1 Carbon Fiber Aero Package and $1,500 ZTK Performance Package yield 1,200 lbs. of downforce at top speed, sticking the ZR1 to the track through fast corners. Compared to the maximum-downforce aerodynamic setup available for the Z06, the ZR1 enjoys 33 percent more downforce with only a fractional increase in drag.
