Sub-frame connectors... Please build them correctly!

I agree about the I-beam and boxing forsure that all makes good sense. I think maybe that saying the rockers are already doing the job and adding weld in floating connectors is doing next to nothing just isn't that black and white. I'd love to see someone do some stress and load tests on all variations! I think numbers and data are needed to go beyond just saying ones margianally better or way better etc. maybe someone should submit that idea to powerblock it something. I'd love to see back to back to back teats of stock, floaters and floor integrated connectors. I just have a hard time buying that floaters do next to nothing. They've been around forever and lots of guys have been using them for along time. They would have gone the way of alot of other gimmicky improvements if so. Again just my opinion



ok my opinion time for what ever it's worth. Since I have no factory data to prove it an can't back it up except for pictures:D and the feel of the car, which is subject to different opinions by whoever is in the car.

The factories did research on it. For example one of the members in this thread stated something about parallel planes not being very effective.. umm look at this from the factory and tell me why they did it then, instead of welding a complete laser cut part. yeah I know money was the reason. but humor me and tell me your thin cut channel welded to thin floorboards will stop torsional effects as well as this. Now I will say that the laser cut part will stiffen up the floor pans.... but that's not the Only part I want to stiffen really and in effect you have a stitch welded box that is EXACTLY the same as rectangular tubing but without the fully welded capability. This (factory) part goes from the rear wheel wells right to the front rocker end caps and is welded to the torque boxes. in essence it is a Hidden weld-on unit from the factory. It's a spot welded C channel It does work well since my 40+ year old car did NOT sag more that 1/8th of an inch when it was flipped over on the rotisserie and that was before I put in the weld on inner ones you say are not as good, now I can jack up the car using a bumper jack and the doors open and close just like it was sitting level and that's on a convertible which is weaker than the hardtops/sedans. My opinion is "if you like your and it stiffens up your car" then well and good for you, mine worked using the other type


Welded and floor frame tied might be the stiffest, but just welded is good for a daily cruiser and a lot cheaper than floor and frame tied with almost as much stiffening. AGAIN just my Opinion and everyone has got one:glasses7:
