I have just replaced mine but now have found out that what has caused the bushings to wear is the fact that the front struts have worn out and that is the REAL problem.I have just ordered some form the USA and will get them fitted next week (will advise the total cost).
You can't replace the bushings you have to replace the whole control arm I got mine from here and they privide a good service at a good price.

When you replace the struts on an Eibach you can't use the standard ones because the car is lowered it puts to much stress on them. You must get adjustable struts.
How do I know all this...because I am a happy Eibach owner.
Post some pics Daphne so we can check out you ride.
