I am not a 1st gen expert, but aren't you afraid of the bolt holes stretching with bolt-on SFCs? I have a 3rd gen and that is why most will not go with the bolt-on version, due to holes stretching.
Most of these cars are being, almost, purpose built for racing of some sort and that will put a very large load on the SFC.
Again, not an expert, just thought I would ask.
