big wing spoiler?

[Monarch_GTS]

Something like this perhaps....

This is a 1-of-1, truly adjustable, downforce spoiler custom built for my Stinger. This car is going road racing this spring, and I've had the car up to 163mph. I can tell you that after 145-150, the aerodynamic profile of the car is not sufficient for those speeds and the car gets really light, loose and starts to lift. This spoiler was designed for ACTUAL downforce to keep the car on the ground at speeds above 150pmh. Say what you want about the style... its certainly Not For Everybody, and this was designed for functionality, not looks.

Not bone stock it doesn't. I did 155 over an arrow straight humpy road and at increasing speed the ride felt more buttoned down, not less.

There is…….this is a screen-shot i took from a youtube video (I believe from late 2016) that i found AFTER I built my spoiler; this is Kia’s test mule at the track ….. isnt it amazing how similar it is to mine….. obviously the engineers knew they needed more downforce for high speed runs.
