Thanks to "MikeLsx" we have a short, fun Z06 video.
I believe you are correct about the stage 1 splitter.I'm wondering, too. But, I've read elsewhere the stage 1 has a splitter; just smaller with a simple radius design.
Just tell them to not install it during your car's PDI. From what I have read, it seems as if they cannot install the splitter until after the car gets to the dealership because it would get damaged trying to get on and off the delivery truck.I believe you are correct about the stage 1 splitter.
I will remove the splitter. My driveway would likely destroy a splitter no matter how it is approached.
