I'll take a cage over no cage anyway. One reason I chose the car I found that already had a pretty good one.
Most of the pro touring cars around here aren't driven nearly as much on the street as people think and lead on. The real danger is on the track, not a 20 mph accident cruising once a month.
Cage that bad boy real good Torino Man. You'll end up more on the track than on the street with that thing. You got plenty of street cars in your stable from what I can tell.
