2019 Corvette ZR1 Ground Effects Installation

Due to the size of the aerodynamic components, or ground effects — front fascia splitter, rocker moldings, rear spoiler, etc. — on the 2019 Corvette ZR1 (Fig. 10) as well as other Corvette models, the parts are shipped from the Corvette assembly plant directly to the dealership separately from the vehicle. The parts should arrive at the dealership before the car.

Fig. 10

The shipping box containing the ground effects may also include additional loose-shipped parts. The list of parts in the package, including part numbers and the corresponding VIN, is included on the shipping label and in a document inside the package.

Directions also are provided for any parts that are damaged during shipping. Replacements for parts damaged during shipping should not be ordered through Customer Care and Aftersales. Orders for the ZR1’s hood, front splitter and end caps, rear spoilers, and front fender vent appliques are on parts restriction.

Refer to the Pre-Delivery Inspection (PDI) form for additional information before installing any parts. The Special Inspection Items box on the form provides details about exterior parts installation for specific Corvette models.


ZR1 Aero Components

The new ZR1 is available in two aerodynamic configurations. The base configuration features a low-mounted small rear wing and the available ZTK Track Performance configuration features a high-mounted large rear wing. Installing the small and high wings require a tamper-proof 5-point T-30 bit. (Fig. 11)

The low and high wing spoilers should never be interchanged. The low wing should not be installed on a car with the ZTK package and a high wing should not be installed on a car without the ZTK package. The vehicle’s handling was designed specifically for the aero components on a vehicle as built. Changing the aero components affects the vehicle’s handling and should not be altered. The ZR1 also should not be driven with either of the rear wings removed from the vehicle, which will affect the vehicle’s handling at higher speeds.

The correct spoiler for the vehicle can be confirmed by searching the vehicle’s build RPO codes.

The aero components on the Corvette ZR1 are different based on if the vehicle is equipped with the ZTK Track Performance Package and/or the ZLZ Sebring Orange Design Package. (Fig. 12)

Splitters are included for standard ZR1 models (Fig. 13) and models equipped with the ZLZ Sebring Orange Design Package. (Fig. 14)
