Yeah they're tinted, but its some cheap tint that came on the car when I bought it. It looks like 35%, but I'm not sure. It's getting redone anyways.
The '99 Jspec is a pedestal, but it flows much better than the 94-96 in my opinion.
This one is actually a painted and installed Ion Dynamics '99 replica wing

So I'm pretty much set on it.
