DSE Subframe Connector Problem
 
Someone please answer this one for me. Below are some pictures of when I first fit the sfc's in the car and tacked them in place and then pictures from tonight of when I tried to fit the subframe back under the car to get it on the ground. How in the world did the sfc's move that much? They were fit perfectly and then tack welded in about 8-10 spots before final welding. When I welded them, I took my time and made 1/2"-1" stitch welds moving around from connector to connector and side to side to keep the heat down.

The seat pan brackets were not in the car at the time I installed the connectors and I consulted with DSE about the floor flexing because of that. They assured me that I would be okay. I was cautious about the floor flexing because of this but it appeared to be fine. It would have had to dent the floor noticeably if the connectors are this far off.

Any suggestions on how this could have happened?

I am sure you can tell and would not have asked but is the the gap between the subframe connectors and the floor gotten smaller, just making sure that is the part that moved.

I didn't measure it before I welded, but yes that seems to be the problem.

Are you sure you didn't mix up the subframe bushings?

I'm positive. Unless there's a difference between the firewall bushing and the rear subframe mount bushing.

I'm not sure, it would have to be noticable to the eye to be off that far.

Mine did the same thing to some degree.I purposely didn't weld the end connector piece onto the SFC until I had the sub permanently in place .....after all body work and tweaking was done. Another thought maybe the way you have it supported.....try supporting at the axles/wheels instead of the rockers/frame and maybe it will sag a bit in the middle. just a thought

I was gonna say the same thing shouldnt you have had it on the wheels for this and also did you have the subframe aligned when you tacked them in

I would try suspending/supporting the body and frame in the same fashion as you did in the first pics to see if that changes anything, but the SFCs look closer to the floor in the second pics to me too.
