Re: Diaper required at Division 1 Tracks?
 

Belly pans can be "home made", diapers can not.
Also remember if you are going to run any D1 track bracket race you will need one 9.99 and faster. That's a D1 Summit series rule.
Also, just a reminder, don't forget your pit vehicle insurance and registration (mentioned in another thread).

Re: Diaper required at Division 1 Tracks?
 

As has been said, required in NHRA Division 1 for bracket racing when running 9.99 and quicker. I installed a custom fit DRE diaper on my former Super Stock car. The fit was good but too tight at the oil filter which Dennis will fix. The install was quick and easy and no mods were required to the headers nor relocation of the oil filter.

I think EVERY car that goes down the track should have a engine diaper. It has been the BEST rule they ever came up with. :D
