Rear trailing arm aluminium bearing with stainless steel bushing, fits all E30 HA in the original eye inside and outside, without having to rework them. This is an own construction and similar to Powerflex bushings, only stronger and harder, because it is made of aluminium with stainless steel bushing.
Improvements: They keep the trailing arms exactly on track. Dampers and springs can work without resistance, because there is no distortion caused by the rubber bearings. This gives the trailing arms good free movement, similar to Uniball. It is recommended to use the rear aluminium barrel bearings and to reinforce the rear carrier.
Set price 4 pcs. (complete for the HA): € 132,–
