I have a couple roll bar questions for all you cranially protected teeners
1) The roll cages I've seen that include a front down bar attached to the floor seem to block window crank operation. Is this true or does it just look like it blocks it?
2) What is the best cage to go with for autocross/street? I want to keep it a semi-feasible street car, so I wanted to avoid door bars and diagonal rear bar unless it is bolt in/out.
3) Does the bar that crosses left to right under the bottom of the dash cause any knee banging problems. (I'm 6' 190lbs)
4) How do racing requirements apply?
