Hey guys, So i just bought an 06 Cobalt SS. It has a few issues that I am trying to figure out before i bring her to a garage. So here is first issue. The car was riding on 18" MSR wheels and i took them off and had installed 17" steelies for winter as well as 4 new winter tires. Since i have installed the new rims and tires the car shakes very strongly under acceleration. As soon as i let off the throttle the shaking stops. The shaking can not be felt through the steering wheel but I can feel the car shaking side to side. The car is lowered on Eibach sport lines.

Any ideas what the problem could be? It would be very much appreciated!
This is my first car purchase so please bear with me

 

Last time I had that problem it was a CV Axle/Shaft.

Does it do it with the other wheels?
Yes = Maybe CV Axle/Shaft
No = Something wrong with one of the rims/tires you just installed
