vibration after spring install?

I recently installed the Eibach ProKit and now have a slight vibration at the rear of the car above 55mph. It didn't exist before the springs were installed and I had an alignment done the day after putting them on. It isn't terrible but definitely noticeable.

Has anyone else experienced this after installing lowering springs?

I also have aftermarket wheels and tires so I intend to put the stock set back on and see if it still vibrates. I guess it is possible to have coincidentally lost a wheel weight at the same time. I haven't had them checked for balance yet -I figured I would try the stock wheels first and if it still has the problem I could eliminate wheel balancing as the issue.

Any input would be appreciated.

Check your wheels to see if there is a spot where the used to be a weight. They use stick on weights so there would probably be some glue left behind or maybe a clean spot in the shape of a square.

~60mph is often a wheel balance issue. I am running sportlines and don't have that vibration.

Thats what i was thinking too, a high speed vibration is usually a wheel balance issue. I should be able to identify that (or rule it out) by switching back to the stock wheels this weekend.
