And another thing to consider cages are seriously dangerous things to hit your head on in the event of an accident, and you're not wearing a helmet.
Can be fatal in even small accidents, especially when the driver isn't held in with a proper harness!
+1 maybe half cage better for the road? i have a road legal track car and half cage is what i got as i dont fancy a cracked nut if i crash on the way to or home from track.
