IHRA roll cage spec for crate motor cars

[Wade Mahaffey]

I was wondering if anyone had any first hand information on any rules update reference to roll cages in crate motor stock. I spoke with Hank Blankenship a few years ago about this. He said there had been talk about allowing the roll cage thru the firewall do to safety. The cars are a bit faster than the old days, and the chassis updates had not followed. The other question is when a cage is used the seats should be upgraded to a race seat fastened to the shoulder bar. I think these issues are most important in the construction of a front wheel conversion for crate motor stock. I would like to use this type of upgrade in my Corvette build, and later on a Dodge Avenger A,B,C/FCM Thanks
