The spoiler itsself is about 2 1/2"wide (haven't measured)
Sorry about the pics... I had someome else hold the phone and take the pics while I held the spoiler up and he had never taken pics with a phone before so he had his thumb on the camera and it was on low res. Not bad for a camera phone.
I'm about to try getting some adhesive to stick it on to take beter pic myself. It's always better to do it yourself because you know how you like it....
(See, I can do the double-entendre thing too)
It does have to be cut down about 3" on each side.
I'ts sitting in my car right now waiting for it's debut trial.. I might do it tomorrow. I'll keep you updated as much as possible...
