Building a diffuser seemed like a very challenging project that requires testing to do right and ensure airflow effectiveness, and a lot of work to fabricate it.

When I saw that the ZL1 Add-ons products weren't mentioned here and they are only $250 max here in the US (less than the price of a single tire), I decided that would be the solution for me when the time comes. It's rare to see a quality effective product that inexpensive. I'm not buying it for show, my ZLE is for track and canyons only so I'll install prior to track day and remove immediately after, I don't care that it isn't pretty. Looks like it will install/remove in minutes which is great.

I'd bet that the vast majority of aftermarket aero does not get wind tunnel tested and is for appearance over performance.
