I think the real threshold of concern to be spoiler-less is ~90.

I ran the car with the spoiler down and deactivated prior to the wing swap, and it definitely gets "twitchy" at 90 and beyond.

With spoiler up, it's stable to the 150 mark.

With the SRT spoiler on, it's PLANTED on the ground clean up to 150. Not a hint of wiggle.

At 60-70 you shouldn't have any issues w/o spoiler deployed. It's a design gimmick so all freeway motorists can watch your wing deploy as you merge onto the freeway, and the kids in the vans go "ooooooohhhhhhh" hahaha.

I don't think the wing TRULY starts to save your bacon until ~85+... otherwise known as illegal speeds.

Happy motoring!
