Sub-frame connectors

Mine were welded in when it was just a shell. Doors open just fine whether the car is on jack stands or the wheels. I would think that if your ride was together, motor in it and what not and you were to put them in you might have some troubles depending on how the car were supported.

I have had a few folks that the inner fenders provide support. While they might provide some I invite folks to try this. Put your car up on jackstands with the fenders on it. Unbolt the fenders and front bumper, leaving the brackets on. Attach a chain to the bumper brackets and then lift the front of the car with an engine hoist. If your ride is like ours was, and our car was a California car with 0 rust in the front of it, it will flex. Ours flexed enough to pop out all the seam sealer. Front end of frame went up about 3.5" before any movement occurred at the jack stand, which was on the frame rail a bit behind the firewall. What this proves to me is that you are relying on the front fenders to provide support. And sheet metal will fatigue after a while....
These cars are flexy fliers. Subframe connectors do help but they are on the wrong plane to stop the front of the car from drooping when one accelerates. What is really needed, in my OPINION, is snout bars (if you have a cage) or j-bars similar to what Dillinger WAS offering. This picture is from the Magnumforce web site showing how they can be done if you do not have a cage.

Triangles, along with boxing, are what creates strength. While subframe connectors help eliminate the flex between the front and rear frame sections they are on the same plane as the frames. True support comes from a well built cage. Not saying to put a cage in your car but subframe connectors are only a part of the equation. No doubt there is going to some folks that are going to try to argue with me over this. Go right ahead... But again, go and take the fenders off of your car and try what I mentioned above. Facts are pretty tough to argue over. Go and look at how a properly built off road cage is built and you will see triangles damn near everywhere.

People will often say motor/mid plates are nothing but trouble thanks to the vibrations they put into the car. But a one piece motor plate coupled with a one piece mid plate are very good at providing stability between the frame rails...provided that they have a pair of fasteners at each end. Again, argue all you want but some of this stuff is fairly simple engineering.....
