More and more and more NHRA tracks are being gobbled up by IHRA. I was told yesterday there is only 1 MHRA track left in FL,, after the end of this month there will be NO NHRA tracks in AZ (until / when / if the issue with firebird / speedworld is resolved) . As I understand it IHRA is more forgiving for the 'show' vehicles 13's and slower, and IHRA tracks have more 'wiggle room' to impose 'track rules'. That meaning for non sanctioned events they can allow / dis-allow whatever making things more racer friendly then the staunch NHRA rulebook.

That said,,, NHRA says if you alter the firewall or floow, (more then 2sq feet for trans / clutch inspection) you MUCT have a CAGE, (not a bar) . Cars required to have a cage are required to have a SFI window net, a SFI trans shield, a SFI flexplate shield..... Most of this stuff expires every 2-4 years and gets thrown in the scrap heap and replaced with something with a new SFI sticker.

When you're dead, it's only a problem for the people around you, because you don't know you're dead. .....It's kinda the same when your STUPID. I just did my taxes and reviewed my SS statement. Thanks to the current administration it looks like I will only have to work till noon on the day of my funeral.
