Thanks for all the reply's.
Yeah the sunroof flex was the first thing I noticed when I bought the car.
It used to only make a little bit of noise right after I would close it, but it does it a bit more often now. I figured the rocker's had something to do with it.
As far as suspension goes, Ive done pretty much everything. kyb agx, w-body store lowering springs, poly sway bar bushings and end links, new control arm bushings all around, trailing arms, and so on.
The car is not anywhere near as floppy as the 1990 Bonneville I had. But that car had way better suspension, and was far more nimble since it had control arms and ball joints out back to keep the camber constant through suspension travel.
and yeah the ones I linked are a joke. Ill have to make some beefy ones myself. The car is a daily so a cage really isint practical.
