Starting about a month ago my car has been swaying from side to side under wide open throttle. It only happens at 80+ MPH and it's only under full throttle. Sometimes it will be going steady but then when i hit a bump it will start swaying as if I were jerking the steering wheel back and forth. Have any of you guys delt with this or have any ideas on it. It's really starting to bug me because i don't remember the last time i've been able to go all the way though 4th gear.

What shocks and springs? If they're still the OEM's that would my guess.

H&R springs, revalved bilsteins, UMI adjustable TA and adjustable panhard rod.
I'm wondering if the bushings in my rear control arm are shot and causing the rear end to dance, but I don't know if those 2 things would even be related.

sounds weird. Kind of like if you had a lot of play in your rear end. good luck

i had this same problem. my cure to this was shorter sway bar endlinks, that did help alot but the main problem was this inside of my tires where so bald due to poor alignment and the fact that i had a 245/40/18 on a 9.5inch wide wheel.

also i had a friend that developed this problem as well and it turned out to be that he was missing a bolt on his Tq arm going through the rear end

Ryan,
did you ever get this worked out? What did you find as my car is now doing the same thing after putting new front and rear sways on, narrowing the rear, and new wheels and tires. I also have brand new Koni/strano springs and it was fine after adding those.
