For some reason when ever going at a high rate of speed, 80+ it feels like the back end moves from left to right. I cant really discribe it but it reminds me of being on a snowmobile without picks, how the back end feels like its always sliding left/right.

What could possibly be causing this, as it does freak me out a bit.

Koni SA 4th Gen | DMS Springs | UMI Single adjustable LCA Poly/ROD | UMI Single Adjustable Panhard Bar Poly/Rod | UMI STB |

Fronts are set at 4 sweeps from full hard, backs at 25%

Also currently running 265/40/18 up front, 285/35/18 out back. Pilot Sport A/S


Any help would be great.

Thanks

I'd take a close look at the panhard bar first, then ALL bolts in the rear suspension... before you drive it again.

Make sure you tightened the LCA's and rear suspension under load.

Going to try it today. I know for a fact that i tightened it under load, but that was with a jack in the center of the back axle in the air. Im going to place the car on ramps all the way around and then loosen it and redo it.
