You could put it on a Saleen as well... you'd just have to trim and shape it differently.
This chin spoiler is off a 93 Bronco. I cut it and shaped it with a dremel and random orbital sander to get what I wanted before fixing it to the car with the existing nose support bolts and a few rivets of my own.
It will all depend on the look you're going for. If you have a Fox Saleen front air dam already then you might want to consider isntalling a custom splitter.
Just some thoughts....
