the GT's are only $800, but my body shop told me it would be at least $2,500 to install, compared to $1,000 for bolt on. i was going to order tomorrow, but when i was deciding, i liked the look of the Diablo's, the angle is higher, but the hinge looks nasty, and its got a bad wiring harness set-up. i'm gonna call around tomorrow and see what kinda prices i can get on installing the universal GT's, because i do think they look better, but i heard there's more chance it won't line up, its weaker because of the weld, and they don't seal as good. is this true?
