The potential for foreign objects entering the cockpit is another reason for updated seats and side nets on both sides...not total protection but better than without...also reinforces the lateral head supports. If that did happen, the HANS would not be much help.

No one said Steve's opinion doesn't matter...but if Steve listens to my suggestions for setting up his sprint car...well, let's just say my many yrs in racing safety makes me far more qualified for head injury discussions than spring and torsion bar rates! <G> A veteran drivers opinion is very valuable...no doubt about it.
