9 second checklist

Looking to break into the 9s this spring. It used to run 10.7. Any new rules or anything I forgot? I've been out of racing for 3 seasons.

He's some things I either did or are planning soon:
Chasis cert. Had to add some steel under the front cage loop.
SFI roll cage padding
Full tranny Kevlar SFI shield
Locking Dip sticks
Neck collar & pants
New window net
New Belts
New Helmet
Renew NHRA membership
Liscense with Doctors forms.
