Mike,
Are you sure your problems at IMI didn’t come from going off track too much????? 👿 You know I’m kidding….
I had a ribtech seat and a sparco rib protector and didn’t have any problems. The seat came nearly up to my arm pits and I was in there pretty tight.
The bumps at Bandi are horrible! There is nothing that can be done there except nuke the track and start over. The rumble curbs tear up sprockets and motor mounts, but that is good for the parts dealers.
