Hi all, just a thought I know its not about engine swaps but we are talking about BIVA if we cut holes in the front valance for cooling the radiator. What is the position when fitting a sun roof either glass, steel or fabric roll back. There are stacks of do it yourself kits instructing cutting large holes in the roof, which is a structural member, does this mean all of these intallations will require BIVA inspections? I a will be fitting a sunroof in the near future should I be concerned.
