So lately I been vibrating on the pedals and steering wheel.

I was wondering if its because my lower i got a month ago.

Im sitting on stock suspension with the 09 lt cobalt

with eibach lowering springs with camber and steering rack spacers.

When I had them it was 1 1/2 have finger space in the front and 2 in the back

now its 2 in the front and 2 fingers on one side and 3 on the other side.

Any idea why this is happening?

also I have around 48,000 miles on my car

 

All Cobalts have one side higher than the other in the rear.

 

mine is a quarter of an inch off from fender to tire on each side in the rear.

 

this

 

If you do the same on the front you will be set up to run ovals
