Not for nothin, but how do the torque boxes look in this car?  How 'bout the subframe?

Speaking of that Paul.

Did the "mechanics" who installed the control arms (or replaced the bushings) torque them with the suspension loaded or hanging?  If they were done while hanging, they could have preloaded the bushings and in doing so induced some additional spring rate into the suspension...making it seem like there are stiffer springs in the car then there really are.

I guar-on-tee this is it.  Sounds like overtorqued bushings not allowing the suspension to move properly.
