If you're looking to maximise the handling on your BMW, billet adjustable guide arms are a great addition to achieve track capable grip. 
By using a bearing mounted arm you eliminate unwanted bushing flex providing far more consistent rear suspension geometry when cornering.

Rubber rod end boots will seal the bearings from the elements and brake dust to maximise the bearings lifespan.
