Anyone have an another explanation for how that really works.
The spoiler on the ZL1, while not as gross as some of the Vipers, is just too big/intrusive for me.
If I were into racing, I might be concerned about the aerodynamics, but for me, a ZL1 is just a good way to get on the freeway - like my ZR1 (which I'm keeping). LOL..

My rudimentary understanding is that the aero tunnel process is there for engineers to create the most efficient way to provide the downforce needed while minimizing Cd penalty. In other words some things, like a blade spoiler, may provide the same downforce as the spoiler, but at a greater Cd penalty.
Also, a delete may cause lift, increasing instability...either way I trust the 100's of hours and engineering expertise of the...engineers. nothing about the ZL1 is an accident.
