I'm wondering about that factory rear wing - it's interesting. I'm not convinced deleting it is best! The "effective" rear angle of the car is much closer to ideal with it in place.

But sounds like it's too late to spend time doing testing to confirm or not.

Aside from that, your list looks good.

EDIT: I'd put the headlight mods at the bottom of the list, priority-wise though, and put the grille blocks near the top.

Please post pics & road trip results!
