I have dropzones the cheapest of the cheap, and I don't get any vibrations.

 

To everyone who has installed there springs, where is the tab facing that's on the top hat. Is it over the pointat the end of the coil or facing inwards toward the motor. Also please state if you have vibrations. Thanks

 

im reviving this thread because im having the same problem. i replaced calipers front and back, rotors, pads, wheel bearing, sway bar links, swaybar bushings, control arm bushings front tires, struts and shocks and springs, passenger axle, steady bearing & mount.

wednesday its getting the drivers side axle changed, and possibly the rear control arm bushings.

also new tires in the front and then rotated a week later to rule out the possibility of out of round tires or bent rims


did anyone find the cure? how come some get it and some dont?

 

Rotated trans mounts help a lot.

 

I just put H&R sport springs on my 2008 LT Sedan and i am noticing a funny little vibration on light acceleration just around the 1-2 shift. I set the spring top coil into the insulator exactly as the factory spring was positioned. Im thinking that it has something to do with the axle/cv angles or possible binding created by the drop. I'm not too worried about it in general.
