The two-way adjustable high-wing kit lowers the top speed but gives the car 60-percent more downforce than a Z06 with the Z07 package.
A few bolts on the stanchion allow for five degrees of adjustment.
The wing is mounted to the chassis to prevent cracking the hatch under load. Every ZR1 comes with a new underwing.
The Corvette team looked at having an active rear wing. The idea was nixed after considering packaging and weight issues. Juechter said that because an active rear wing can provide low drag and high downforce when it's up they decided to "just leave the damn thing up." Underbody aero was developed with the Corvette Racing team. Balancing the big rear wing required more aero up front, so an inverted airfoil aids without having a giant shelf out front.
The high wing is part of the ZTK Performance Package (Chevy loves its build codes). Juechter and Chief Designer Top Peters say the ZTK package is equivalent to the Z07 package on the Corvette Z06.
In addition to the airplane appendage, the ZTK kit adds a front splitter with carbon-fiber end caps, Michelin Pilot Sport Cup 2 tires (the same ones that are on the Z06) and different tuning for the chassis and Magnetic Ride Control.
That's right. No fancy spool-valve shocks like on the Camaro ZL1 1LE.
The ZR1 uses a short/long arm double wishbone setup with cast aluminum control arms and transverse-mounted composite springs both front and rear. It is a Corvette after all.
While Pilot Sport Cup 2s are optional, the car comes standard with Pilot Super Sport run flats.
The staggered setup - P285/30ZR19s up front and P355/25ZR20s out back - cover carbon-ceramic brakes with calipers the size of Dwayne Johnson's forearm.
With the Cup 2s, expect 60 to 0 mph stops of fewer than 90 feet, real world-class stuff.
The debut ZR1 comes in a special Sebring Orange Design Package that adds orange paint and brake calipers and orange stripes on the rocker panel and splitter.
Inside, the car gets orange seat belts, orange stitching and bronze aluminum trim.
In addition to the performance parts, all ZR1s are available with heated and ventilated Nappa leather seats, a carbon-fiber rimmed steering wheel, a Bose stereo and GM's Performance Data Recorder. Like other Corvettes, the ZR1 is available with multiple seats with varying degrees of bolstering.
