Should I add a Trans-am style spoiler?

Are those your LT-III 18" rims?  Care to share the specs on those and the tires?

are you sure those front wheels are wide enough..?     sweet rims Brad 
I don`t think such a spoiler would be streetlegal here.... it could harm a pedestrian when you run one over     

   Like running one over without the spoiler wouldn't harm them. 
I bet it would be a popular option in France? A portable guillotine for slow moving pedestrians!

Yep  just got them mounted up this morning! 
18X11 on all 4 corners
315/30/18 front 5" backspace with a 1/2" spacer
295/40/18 rear 5 1/2" backspace with a B-body width rear end

Wider tires on the front?  That's unconventional?

So is trying to make a BB handle!   They are not that much bigger and I had to work with available sizing. BB tend to push so wider tires should help with that.
