Alright... I have a 99 GS4 with 37K miles and I installed the L-tuned combo not to long ago (1-month). The car rides fine when I am in it alone but when I have three or four other adults in the car at highway speeds 75+mph the car bounces like crazy. Could this be faulty struts? The body feels like it is floating independently from the wheels. High speed braking from 80-30 feels very unstable also. What can be done to correct this problem? I have a new set of L-tuned shocks that Darrel sent under warranty but I was wondering if anything else could cause this. The dealer inspected all the suspension components and said there is nothing out of the ordinary with the car. Anyone with the L-Tuned combo also experience this?

 

Very subjective....Maybe you're too sensitive.....your car bouncing like crazy maybe normal for the rest of us...LOL

Try riding in another Ltuned S/S setup GS...and see if there is a big difference.

 

Same here, had a full car today, and I felt the rear was slanting alot, also got a wheel shake when braking at highway speeds.

 

wheel shake when braking means warped rotors, not a bad suspension

 

Anyone else have any comments?
