I just installed those Bilsteins. I believe I have the retainers on one side incorrectly. I can't be sure from diagrams I found on A.J.'s website, but here is my question.
Their are 2 retainers. Is the bottom one cupped and the top one flat?
If the cupped one is the bottom one, should it be located so that the inside of the cup is pointing towards the top part of the shock below upper strut plate cushion?

Also, looks like I should have located the coils so that the end of the coil is on the wheel side and the end would be pointing towards the front of the vehicle. If I am looking directly at the side of the wheel, the end of the bottom my coils is pointing towards me. In A.J.'s photo, the end of the coil is facing the front of the car.

How big of a deal is this?

The reason I looked into this, was after having the tires installed and aligned I drove it on the expressway. I noticed at ~60-65mph, I was getting a little vibration in the steering wheel. I was thinking the wheels needed balanced better. They have no weights on the front wheels and said the new Michilens were much better tollerance on being true.

I guess I'll redo the Bilsteins and coil rotation and then see if I need to take it back to have them check the wheel balance. Ugh, hate to tear this apart again, but I am learning :-(

I'll wait on answers before I tear into it.

Best regards,
Doug
