subframe connectors

[v6spider]

Here's my version of connecting the front sub framework of the unibody to the rear arch frame work.

Nice!
I've long thought of doing that, but I just could not bring myself to cutting into those rear floors

Hi Vandor,
Well the choice wasn't hard to make because of the rust that I had and I wanted to use my firebird seats so the floor needed to be flat. And I think this will really help with stiffening it up for my v6 power plant as well.
Cheers!

cool now i need to do that too...

Rob please stop doing mods to your car or I'm never going to get my car done

[v6spider]

Sorry Daniel! I have the mind of a hot rodder! And this mod is necessary I think for added stiffness to support my v6.

Cheers!

Here they are finished. Both subframe connectors done.

Rob,
What you really need is an X-brace. The spider has good strength in the vertical directions but is lacking in the torsional or twisting. That being said, every little bit helps.

How would you build around the drive shaft?

Has anyone used sub frame connectors that angle in towrds the center and installed shallow removable cross members creating some additional structural rigidity?

Hi Everyone,

Hi Ted: always good to hear from you. I was thinking about x bracing but I was concerned about it getting in the way of my 2 1/2" dual exhaust. I have an idea about how I could weld it in to the framework that is existing. however i am not to sure about how one would tie it in to the opposite side. It definitely is a great idea I just don't know how to execute it effectively while not interfering with the drive-shaft and the exhaust (Like Daniel mentioned)..i am converting to 3 -link just so i can have dual exhaust all the way out the back... I was toying with the idea of making a new transmission brace that ties in to the frame work and also the existing tie points that might be ticket for the x brace tying in and making that work possibly

TX82FIAT: You kind of lost me on that one... although the uni-body gets its strength from being spot welded together and now even more with extra tack welds also that i added..i think the bolt in bits you refer to should be welded in to be more effective.

just a thought...

What are you going to do for a gas tank?

I have a 16 gallon aluminum racing tank that goes in the trunk that has a gm style sender...all my gauges are autometer phantom series ..I basically am ditching a real spare for the tank..
