SFI roll cage padding.
The car is built for 8.50 tech, does it run 8.50 now, no.
But there is steel bars 8 inches from the side of my head. So in any kinda side impact my head is fighting for space with a steel bar.
Was is the smartest decision I ever made to build the cage around the driver? Probably not but I do want to to survive a crash at 150MPH at the strip and still not die in a 30 MPH crash on the street from my head hitting the cage...
This is part of the learning curve of building a full out race car and wanting to keep my license plate...
