You should be disappointed if it doesn't run fast enough to need a rollbar. You might as well get it done before you go to the track. Don't be like me and beat it mercifully for a few years(only running low 12s) and end up with a bent drivers door and torn up door striker. Racing whenever the track is open and lots of low 1.6 60fts were hard on my car with no cage and no frame connectors.
