Rear end wiggling on moderate-hard turn

Any thoughts on how to correct rear end wiggle on turns? On what I would call a moderate turn (a safe but spirited 30-35mph on a two lane turn in the left lane) the rear end wiggles very hard and makes the car feel almost out of control...

Any insights are appreciated.

Might not be the car. Crossing a small but abrupt change in road contour will make a stiffly-suspended car move around more, especially under moderately enthusiastic acceleration. Putting the left side wheels over on the other side of the road crown might even be enough.


I happened to encounter this particular condition a couple of hours ago.

Not enough tire for the power level you are running? Even with similar suspension mods as yours, coming out of a turn in 2nd or 3rd, I have to be very careful with the right foot on the OEM 275 rear tires and perfectly smooth road.

Upgrade the bushings. Maybe your sway bar is set to stiff. Can try those to see if it helps.

do you have an alignment print out?

Check the bolts in the rear to be sure they are tight, including the cradle.

does this happen when you cross the center of the crown in the road?
If it is, then it's possible that you have to much rear camber, and the 'grip' is changing from side to side.

Thanks all. I'm about to make an appointment with a top notch alignment shop that does cars like ours. The rear is starting to creak when I get in the car (I'm heavy but not THAT heavy), so I'm thinking I have a few loose bits...

I have gotten the sway bar end links' bolts coming loose a few times as well as the collars on the old sway bar that caused the "wiggling". You might just want to craw underneath to check them out before take in the car.
