Rollcage issues

[bret]

One thing I noticed when looking at video of the Tiger Cage is that the main hoop is right behind the head area of driver and passenger......I'd be a little concerned about head injuries in a street accident when no one is wearing helmets. Is there some structual reason the hoop is not a bit further back?
Just asking...not taking a shot at your system.

This is an area that is tough to address short of building a custom fitted rollcage. In general, we place the main hoop in line with the leading edge of the B pillar. This seems to work well with both the car and the largest percentage of drivers out there.
