The C8 Corvette ZR1’s return is accompanied by the resurgence of the ZTK Performance Package, a formidable option that promises to raise the already impressive capabilities of this supercar.
This package, which was previously offered with the C7 ZR1, introduces a series of enhancements designed to optimize the ZR1’s performance on the track. The ZTK Performance Package includes a comprehensive suite of upgrades that focus on aerodynamics and suspension.
By incorporating a more aggressive rear wing, a tall hood Gurney lip, and front dive planes, the package significantly increases downforce, enhancing the ZR1’s stability and cornering ability at high speeds. These aerodynamic components are meticulously crafted from woven carbon fiber, ensuring a lightweight and durable construction.
In addition to the aerodynamic enhancements, the ZTK Performance Package also features a revised suspension setup. The engineers at Chevrolet have carefully tuned the springs, dampers, and anti roll bars to provide a more aggressive and track focused driving experience. The package also includes high performance tires that offer exceptional grip and traction, further enhancing the ZR1’s performance on the circuit.
While the ZTK Performance Package does not include any upgrades to the braking system, the ZR1 already boasts powerful carbon ceramic brakes that are capable of withstanding extreme demands. These brakes allow the ZR1 to accelerate and decelerate from 80 to 200 mph and back to 80 mph in just 24.5 seconds, demonstrating its exceptional stopping power.
The ZTK Performance Package is a compelling option for ZR1 owners who seek to maximize their car’s potential on the track. By combining aerodynamic enhancements, a revised suspension setup, and high-performance tires, the package transforms the ZR1 into a true track weapon while still maintaining its everyday drivability.
The 2025 Chevrolet Corvette ZR1, with its ZTK Performance Package, is set to redefine what it means to be a high-performance sports car. While the standard ZR1 boasts an impressive 1,200 pounds of downforce at top speed, the ZTK package is expected to push that figure even higher, though the exact amount remains undisclosed.
To complement the increased downforce, the ZTK package includes a retuned Magnetic Selective Ride Control 4.0 suspension and Michelin Pilot Sport Cup 2 R performance tires with a unique TPC spec.
Rigorous testing on tracks like the Nurburgring, Road Atlanta, and Virginia International Raceway has ensured that this car is not only powerful but also reliable. Under the hood, the ZR1 features a hand assembled, twin-turbocharged 5.5 liter V8 engine that delivers a staggering 1,064 horsepower and 828 lb-ft of torque.
Paired with a dual clutch eight-speed automatic transmission, the ZR1 is capable of reaching speeds of up to 215 mph. While the pricing for the ZR1 with the ZTK package has yet to be announced, General Motors President Mark Reuss has hinted that it will be “aspirational but obtainable.”
