granetelli upper and lower control arms and lowering springs did it for me. It jerks hardly at all anymore. Im not sure if the springs did anything but the control arms sure did change the placement of the rearend

I got them off of ebay for190 shipped. They are granetelli's just without the label. Greasable bushings and everything. Swapping them was a bitch because some of the bolts wouldn't slide out so I cut them and drilled them out. Its a good weekend job. hell im 17 and I can do it.
As far as what the jerkyness is, everyone I know witha 99-04 gt has the bucking when just driving through a parking lot in first. I think this issue is just for 5 speeds.

i understand what you mean with jerking.....kinda chirping the tires right?

as for where are control arms ..... SIMPLE DEF: they are the black things that hold the spring!

Control arms are a hell of a lot easier if you have a lift. Pretty simple swap.

I mean jerking when your driving through a parking lot in first getting on and off the gas.

My car did this when I first bought it.This was my first time driving a manual transmission car in decades.I found out by steadying your foot by resting it on the carpet you can avoid the jerking.It was caused by my foot alternately pressing and releasing the gas pedal due to the inertia of my body causing my foot to move the gas pedal.If left to develop without damping it out,it would get worse until you would have to raise your foot off the gas to let it settle down. A better explanation is pilot induced oscillation.
