Title: Subframe connectors and seatbraces wall thicknesses?
Post by: GrannysBird on July 12, 2010, 02:41:39 PM
Hey guys I'm getting ready to put some connectors onto the bird and will most likely build some seat/cross braces as well, but I'm a little uncertain abut what wall thickness I should be running on the 1x2 tubing for the SFC's? At what point do I go past overkill? (I'm not planning on cutting up my floor, yet)

Also, are the seat braces mainly to provide a more robust mounting point for the seat tracks or to stiffen up and prevent twisting of the SFC's or both? I would imagine the main benefit of having them would be to stiffen up the chassis.

For reference I'm shooting for something resembling t3skidoo's setup.

I just installed these on mine and called it a day:

http://www.globalwest.net/1979-2004_Mustang_performance_suspension_parts.htm#Subframe%20connectors:

The subframes (P/N 918) are full length and are mounted to the outside of the factory subframes.  I just used the Mustang seat support (P/N 920) as directed by GW.  Been on the car for over 10 years and doing just fine.

The car also has the Griggs uppers which require cutting the floor pan but these were installed a couple of years after the GW units.  With the lowers and uppers you can jack one corner of the car off the ground and it will end up with three tires off the ground and the doors will open and close with no issues.

At a minimum use a full length subframe connector with seat supports.  The Griggs uppers are not that hard to install and look very nice when finished.

just get 10' of 1X2 and see if chuck has any seat supports left. If not, you can make your own by cutting up some extra 1X2 and making your own.
