Couple of questions. I have a 95 525it, about 111k miles. I have the front end shimmy, not really bad, more significant when I hit the brakes, so I'm thinking thrust arms. I get the car on ramps and take a look and there are two things I'm not sure about.

First, the lower control arm is alluminum, did the 95's come with this stock?

Also, in the picture below you can just make out the inner bushing of the thrust arm. I notice that the trapezoidal plastic part is blue. Is this possibly a stock bushing or an upgraded one?
