On-Road and At the Track

“The ZR1X balances impressive power with robust brakes specifically developed with this car in mind. The J59 braking package, standard on ZR1X and an option on ZR1, is a clean-sheet design intended for superior heat resistance and ultra-responsive braking. Alcon 10-piston front and 6-piston rear calipers are mated to 16.5-inch front and rear rotors – the largest diameter rotors ever offered on Corvette. The rotors are carbon ceramic, constructed with continuously woven carbon fiber threads. “This is the most resilient production car braking system we’ve evaluated within GM. And during testing, we saw J59-equipped Corvettes achieve 1.9G of deceleration from 180 to 120 mph,” GM said.

ZR1X is offered in two chassis configurations that both have magnetic ride control (adjusting to the vehicle’s mode, driver inputs and the road surface for optimal control.). The standard chassis, accompanied by Michelin PS4S tires, is said to be a comfortable touring car on-road and a highly capable Corvette at the track. The optional ZTK Performance Package incorporates higher spring rates and is firmer. Paired with Michelin’s Pilot Cup 2R tires, this is the pinnacle of Corvette performance, GM said.

Customers can equip the high-downforce Carbon Aero package with a standard chassis ZR1X, adding dive planes, underbody strakes, a hood gurney lip over the front heat extractor and a “highly effective rear wing. This package is capable of 1200 lbs. of downforce at top speed and comes standard on ZTK-equipped cars,” GM said.
