Where do you get the SFI specs? My Chevy 2 has a copy, kind of, of an Alston chassis. I watched a film and thought, I can do that. My son doesn't think it will certify. I'd like to know if it needs something additional before I try to get it certified. It runs low 10s and goes straight as an arrow. I just want to make sure that it is completely safe. By the way, I voted for this thread. Great stuff.
