I tried a few different types of thrust arms and suspension components in my E28. Of course bushings are an issue but once I graduated to the 750iL bushings (trimmed) that seemed to go away.

The big remaining difference is the ball joints and boots. Meyle parts were *CRAP* in this regard. Within a year two boots had failed, within 2 years all needed to be replaced.

So the best in my experience is Lemforder. Seems to be of much better quality and also to last longer. Costs more but at least to me - definitely worth it.

Enjoy!
