Rollbar Questions?????/

They work just fine - they actually extend rearward at ~45* angle - much like the 67 and 68 Shelby factory equipment. If they were straight up & down, I'm sure they wouldn't be effective. I think the old SCCA spec was "horizontal, within a range of -5* to +40*". I've actually made the mistake of being cinched in too tight - not a good thing when your hands are 2" short of reaching the ignition switch! There's no "give". Easy, complete rear seat access was important to me, so compromises had to be made.

A too-high shoulder mount may be less-than-optimum in a rollover, but it's not "dangerous" like a too-low mount would be in any type of crash due to spinal compression.
