you have a great point, and **** no i wouldnt take the saw to my roof myself, so I dont know. Im just dreamin because Ive always loved targa tops and now I can have one. Plus the CF roof would match my hood, well see I gotta research it some more. PLUS i just took a look at their website and it looks like **** with the roof on, and im noticing it looks bad right over the rear window, theres this big ugly piece of fiberglass that sits there, it doesnt look like it was meant to be there, if you get something like this you want it to look factory, im prob not gonna do it
