Spoiler with no splitter
Looking to add a Z51 or high wing spoiler to my new C8. My driveway has about 1/16 “ clearance if I pull in at the optimal angle, so a splitter is probably a no go. I will seldom be at speeds over 100mph and don’t intend to ever track it. Do I need to worry about the front stability?

GM has never told what the Top Speed of C8 is with the High Wing is, just that it has less drag. Sounds like the spoiler applies max rear Downforce, at lower speed vs HW.
With C8's base design, moving passenger compartment FWD, toward the front wheels, that along gives it 400 Ft/Lbs of max downforce at the base of the windshield, that may play a factor in High Wing not effecting frontend stability at lower speeds.
I'd do the High Wing if you don't want to install a front splitter. This is coming from a man, that ordered Z51 with a High Wing, as I prefer it's look. The ricer look to me is a C7/C8R race car High Wing. .
