Stock non-M arms are made from sheet metal that is merely spot welded together, which tends to flex and bend under moderate loads let alone track day or racing stresses. If you use grippier tires and an engine with more torque, then the stock arms aren't able to provide stability and consistent handling. BMW E9X/E8X Rear Upper Arms, which include both the guide (traction) and camber (wishbone) arms, feature gun drilled 2024 Aluminum links that are Black Anodized to prevent corrosion and provide a durable finish. Our exclusive 360 rotating 6061-T6 Aluminum Clamps allow quick, precise adjustment with Blue Anodized Titanium Socket Head Cap Screws, which shaves even more unsprung weight without compromising strength.
