We run a spool in my buddy's Challenger never had an issue with it and it's a street car because the cage won't pass tech for the times he runs. He drives that car everywhere and the only issue has is he needs to make sure he doesn't get caught in really tight turns. When he does he ends up dragging a tire. Ive only run stock a posi in my cutlass but that Challenger has no issues with the spool.
Depends on what you call no issues. You already know it won't turn - try parallel parking it, try jumping on it to pass a car on a two lane @ 30 mph (on second thought don't) it's not save. It won't handle or make evasive moves. Yes people run them on the street - it's safe as long as your goin straight.
