Steve, I don't have a rule book, but are you saying that S/ST, the entry level class, where the index is only 10.90, requires a diaper?

Correct...that and the flywheel shield were the only two things I had to add to the car for S/ST. I know a lot of tracks were requiring a diaper on Sub-10 second cars as well for their weekly bracket programs. I don't know if I needed the flywheel shield though as the car runs less than 135 mph?

I don't think the diaper should be mandatory...but it's definitely cheap insurance.

For what it's worth...The rulebook does state that a minimal number of slots or holes to "clear frame, steering, or lines" is permitted.
