Who hasn't seen the in car camera shot of Richard Petty steering to the wall with a tire going down to reduce the impact of the hit that was going to happen soon ?
As NASCAR wall hits go it was pretty gentle, but the impact stretched his bod to the extent that his head rang the bell on the far windshield post.
The impact was a real shot and the crew chief asked him on the radio if he was alright.
With his suddenly slurred speech he answered that he was "OK".
It is obvious he suffered cumulative brain damage.
When you build restraints, consider what is going to happen to the unrestrained driver parts that will leave without you and often come back broken.
In a recent smack to the wall, Ms. Force recorded a 65 G momentary hit that makes you wonder what would happen to a loose fitted and un-padded containment.
Try hitting the table with a closed fist from 1 inch away and compare that with hitting it again from 1 foot away.
Repeat the 1 inch part against the old style insulation rubber and then try the SFI spec foam.
Please, try it your self at home.
If you have spare driver parts, I guess that would be OK too.
