Just to clarify a few lingering things in this post.

1) You don't need a rocker/sill bar in a cage unless you have cut out more then 2sq ft of the original floor.

2) You can add 1 5/8" to a 1 3/4" existing roll bar. I just clarified that this year with NHRA.



This is true but my friend has a 6 point in moly that is 1 5/8 and has never had a problem at tech with any track. I have personally seen it go through 4 different tracks tech. Remember you are installing this for your own safety.
