The STI that block driver? I don't see why not. It's completely gutted and rollcaged, so you might run into issues having the cage in while on a public roadway, but other than that everything else looks intact.
South Carolina it would be legal, plus they don't have emissions tests. Heck even cars with no doors is legal. No helmets, legal. I love my home state. Buncha drunks that make rules that will end up killing people. Oh well. Lmao
