Want to see all the GM details and pictures on the PDI aero component installation.

2019 Corvette ZR1 Ground Effects Installation

Posted on July 1, 2018 by blogadmin

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)

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

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

Spoilers

I prefer underbody aero ..

As effective as huge wings are creating downforce i personally prefer ferraris use of underbody aero...

makes servicing a little more difficult at times but it offers a sleeker look.

a small rear spoiler is ok for the street but the monster spoiler wings out back are a little over the top for tje street cars in my opinion.

i presonally prefer a little less downforce as i just dont need that for my daily driver.

putting stuff in the trunk can be more difficult as a daily driver as well in front mid engine cars as well..

active aero is cool as its more seamless in appearance while the car is stationary or mormal speeds..

ive seen the spy shots of the new porsche 992 set to debut this coming year and from what i can tell im not even a fan of their new rear active spoiler when deployed.

i am hopeful their will be a standard model that doesnt offer active aero as standard but rather as an option..

if active aero is standard so be it..,not a big deal but if its an option on the base car and it looses a few pounds of downforce..im ok with that as long as consumers can still get the z51 heavy duty cooling and suspension..

ive always believed the jeavy duty cooling and heavy duty suspension are worthwhile options both in terms of performance and durability long term..

active aero or big monster wings..not so much...

my bet is active aero is standard and thats fine

My personal preference for the ME would also for the “whole car” to be one aero function, a la the Ferrari 488 GTB. Whie I still have a crush on the looks of my C7 Z06 with all its tacked on sharp-edge aero components, and love the ZR1 for what it is, my choice would be that the ME’s aero to be more “integrated.”
