step 1. get the GMPP handling kit

step 2 Install the Koni'* and some lowering springs

OR the GP GXP springs/Struts

OR of your happy with the ride height go with the Intrigue/Impala rear springs to fix the *** sag that the GP'* always have

Its not from the Eibachs....ALL lowering springs will do that over time. Shorter axles fix the issue, or the ZZP offset motor mounts.

The stock axles (halfshafts) are to long and hit the tulip going over bumps. This is also what breaks LSDs-but thats a different story

I think the bouncing is called pogoing, not sure if that is spelt right, but anyway there are anti-pogo washers you can get to take the bounce away.

Try the ZZP offset mounts, it MUCH cheaper that shortened axles. The mounts aren't the way to fix it IMHO, but they do the trick.

Shorted axles are going to be ~$250 or so, they are rebuilt/modified OEM axles. The swapped cars use these frequently, and is a necesity once they are lowered.

The pogo mod can be used front and rear...and they work great.
