What I have been told by the owner of my local track is that diapers will be required:

1) At the ET finals this year if you're 10.99 or quicker
2) Will be required in S/ST next year

I'm HOPING that rule doesn't filter down to the 10 second ET cars...that would be a shame.

Be interesting to see responses, cuz on our Duster...there's NO way. We'd have to change oil pans and run a true fenderwell header and then maybe one might fit.
