Well first I would look up the parts in the partsshop fastlane here to see if the price is better, which is almost always better priced than other places.

Second, I would think that the wheels/tires would have not been acause for this as the 17" wheel package was an option on the car from the factory.

The E55 has 17" Wheels from the factory. I would check to see if the control arms from the e55 are different than yours, if they are the same, then I would think the wheels are not a factor. If they are different, you might look into using those ones instead.

I hope that helps you in your fix. If the wheel is wobbly because of it, I would get it fixed.

i'm not a tech, so thats just my opinion.
