subframe connectors and stock class Q

[Tom keedle]

thanks guys, i wasn't sure if it was legal to run them thru the floor if nessassary
(obviously welded in)...
i've been told that in late 68 americans and all 69's that amc added them in oem.
i know my 69 has 'em but the 67 don't...


2X3 X .125" ok? (nhra book says so) or would you suggest a thinner wall tube?

Sub frame connectors are only legal when used with a roll bar or cage.

Thank you Mark.

I went back to the rulebook and couldn't find this. N/S and above are not required to have a bar or cage. With this implication, you couldn't tie the subframes of an N and up car. Does your V/SA Mustang have the frames tied? From the pictures, you don't have a bar in it.

Yes, and so did the N/SA Omega before it. Teched in by Travis at Indy in '04

Dwight, I can't find any place in the 2008 or 2009 rule book that says you can't have frame connectors without having a rollbar. Billy

Tom, I'd bet there are less than 5 people on here that know what an 01 body is..... LOL.

Is that 67 a 232 2V ?

I was wrong, you are correct. Brain bloat or something.

Again, just my opinion, but 2x3 and .125" seems like overkill on strength and weight, not to mention possible clearance issues above and below the floor. Having it welded into/through the floor with the inner roll bar legs should make 2"x2"x.083" plenty strong. Then you can add any extra weight where you want to and where it will do the most good.
