Or, you can go to the main NHRA page and hunt for the tiny box that reads "Racer Updates" among all the distracting clutter, and click on the "Racer Updates" button. Why this wouldn't be on the main "COMPETITION" tab is beyond me (more logic).
Biggest change I can see is that starting Jan. 1, 2012 oil-retention devices (e.g. diapers or belly pans) will be required on all S/St entries, and beginning June 1, 2011 all roll-cage padding in S/G needs to meet SFI spec 45.1 where the driver's helmet could hit the roll cage (also for cars running 9.99 or quicker).
Oh, and for you guys with secondary braking systems, they're now going to be permitted as long as both are connected together and activate all braking systems on the car at once (i.e. you can't use the hand brake to only control the front brakes).
As a side note, did anybody know that the maximum burnout time is 5 seconds? That's a pretty long burnout, but I honestly didn't know there was ANY time limit...
