i bought a super s spoiler i havnt fitted it yet but went i put it on to measure where the holes should go but where it sits it looks like the boot wont open wen i put it there :S
but that not the issue its where they go wider at the ends it goes a little over the roof but obv i have drilled the hole im just holding it roughly where i think it goes lol don't really want drill holes and it wrong lol
you obviously dont know where it goes as it doesnt go over the roof where it goes wider. well as far as i know there are premarked hole, and thats all you really need to know to install one.
i,ve posted up pics on at least 2 threads in the past, there a 2 circular indents on the inside (where your socket will go) and if you mount it too far forward, then yes it will catch the roof
