Would anyone happend to have the specs for IHRA rules on roll cage/bar requirments?
Im building it in the next month and would like to do it right the first time and not have to rebuild it haha.
Materials? and full specs?
I dont feel like buying a rule book for 10 bucks!

 

I would suggest building it to NHRA specs instead. they are generally more strict, so if you would pass their rules then you'll pass anybody's. and you can download the rulebook http://www.nhra.com

 

sweet thanx..
