I've posted before about this; the FCP Groton arms use BMW bushings and the arms themselves match the casting of the arms I pulled off my car exactly - except the Groton arms are missing the cast-on BMW part number.Originally Posted by avitt2
That leaves the ball joint as the only slightly uncertain bit - and it, too, looks identical to the one I pulled off.
I know they have a very good reputation among the RWD Volvo community for their suspension parts - I have no reason to believe otherwise in this case.
