I drew this out and the only thing that I am concerned about is that at least one hole is going to be close to another. Call me paranoid but I would be scared of ruining the integrity of the hub. I am planning on pushing 600+hp to the ground with this car. I would just like to have the piece of mind that nothing is going to fail.
Quoting iceman69510:
You seem to have access to cool machine tools, just remove your rear hubs and redrill them for 5 lug. Need 2 new stud and some new holes.
