subframe chassis strengthening
 

Hey guys. new here. I am building a 68 Dodge Dart GT and had been asking questions on another board and was referred here. I'm going to be installing subframe connectors and was thinking while I'm at it I could instead of the standed front to back connectors I could install them in an x style from the front driver side to the rear passenger side and the same for the opposite. crossing and connecting in the middle. I'm going with the independent rear suspension out of a 89-97 ford thunderbird so my driveshaft won't be moving up and down it will be in one continuous position so I won't have interference with the connectors.

I just figure that connecting front and back and opposite corners of the frame should add some nice structural integrity.

So are you going to put a passthrough for the driveshaft?

What about exhaust....fuel and brake lines etc etc...

It can be done and I would think that it would be somewhat stronger but is it worth the extra work and headache....I doubt it.

With all the new full aftermarket frames out there...how many do an X for the middle section ?? If they do, it usually just part of a full frame.....

If there is room, all should have it. Check out our Max-G frame.

Exhaust and fuel lines are easy in these cases. For exhaust, weld in some large diameter (1/2" larger than your exhaust pipe size) DOM as a pass-through, and bulkheads can be used for fuel and brakes.

Any type of crossmember is a good idea, but make sure it is placed properly so all strength benefits can be utilized, otherwise it will just make the car a bit fatter.
