Default SLIGHT SHIMMY IN FRONT AFTER LOWERING?

I just finished lowering my 2003 PT Cruiser GT Dream Cruiser and i feel a little bit of shake at low speed under acceleration, I lowered the car 2" front and rear and noticed the little bit of shake immediately, it's fine in 3rd, 4th and 5th gear, no shake what so ever. Any idea what might be the cause of this? I do know the car needs all the control arm bushings replaced, could this possibly be the cause? Or possibly the tires causing it? I would appreciate any feedback if someone else might have experienced this issue, thanks!

Do the arms, get an alignment, will likely be better then.

How do you know you lowered it 2 inches? Was this from the chassis specification in a FSM or your own before and after measurements?
What spring kit did you use?

After I have driven the car for a couple of days it has actually settled down to about a two and a half inch drop, these are from measurements I took myself at the wheel well, I used Tien front coils. The car handles great and the ride is really nice, other than that little bit of shaking I'm very happy with it

That sounds more like it!^^^


The vibrations, shimmies etc., may simply be parts that are worn and the wear amplified by the new ride height as well a slightly firmer ride quality the Tein spring can have. A complete examination of all chassis and suspension parts including the tires and wheels will result in finding the part or parts that need attention.

How do you like the urethane bushings? I want to rebuild my control arms but I did it last year on my neon and they were kind of a pain pressing the bushings out and the new ones back in, at least on the big press we have at work anyway
