Default Re: Free G-body chassis mod... highly recommended

One of these days I'll get around to doing the rear frame brace mod, but I think I might weld it in. I just don't know what kind of difference it would make in a non T-top car though.

Having done it to two Cutlasses both solid roof and a Delta... It makes a difference.

I would like to weld it in, but for now, it works...

the ass end of the car moves in one motion and the suspension actually does the work.. the frame doesnt seem to flex like a go-karts frame anymore..therefore canceling out a lot of noise too.. i couldnt believe it..

Like ive said ive owned my car for almost 9yrs now.. i know every little squeak and groan rattle and clunk.. and this stupid mod made most of them disappear and the ride more firm...

This, bracing the forward frame horns together, and triangulating the rear spring perches are high on my list of to-dos. Once I sit down and actually look at the frame, I'm sure I'll find more to do. FE3X braced the snot out of his.

Something else to consider if any of you are doing body work, welding a lot of the body panels solid instead of the factory spot welds REALLY makes these cars more rigid.

We had to replace the trunk floor in my car since mine was rusted out in a few places. That sucker is welded in with one continuous bead and its amazing just how much more stiff the body feels and acts. Granted I haven't had the car on the road but just from jacking the thing up and putting it on jackstands you can tell things are twisting around anymore.

And things have really gotten better after putting the new roof on. Because like the other panels, it got spot welded in the window channels but along the A-pillar, B-pillar and C-pillars, it was welded with one continuous bead. There won't be any cracking at the B-pillar now.

I need to make a new rear bar for my car since mine looks like swiss cheese. Mine essentially looks like Luke's except that I used 1.5"x1" rectangular tubing. However I've drilled holes in it over the years for different things and now plan to make a new one that I weld to the frame. I'm just waiting to get more of the body work done so that I can make sure nothing is going to hit.
