I agree that a in a high speed roll there is a possible question re protection with the Librands but a better chance in a " topple" at lower speeds.
In our car the critical line from cowl to rollbar is ok for head clearance. The Librands is rearward leaning too so no head issues...the head restraint on the seat is still effective.
The chassis is stiffer, noticeable more when reversing off the drive onto the road...no chassis flex now with the rollbar compared to pre rollbar. The car feels more planted when driving too.
My seat is set back to maximum and not affected by the rollbar, it has lost 1" approx travel due to being lowered off the wooden runners and hits the bottom of the wheel arch. I could take the corner off the seat to regain this but not necessary, I am happy with the seat distance. The passenger seat is not lowered but still has no head issues even when back fully.
