BMW G8X adjustable Rear Upper Arms (RUA) are an absolute necessity to maintain proper rear camber and reduce tire wear on the street and track. The stock BMW setup has an aggressive camber curve through bump travel, which is very apparent on lowered cars. Excess negative camber causes premature tire wear on the inside edge, and reduced traction on acceleration while too little camber will limit rear grip while cornering. Our Rear Upper Arms provide a wide adjustment range for precise rear camber alignment that is easily optimized for street or track driving while eliminating bushing deflection with smooth articulating Teflon lined rod ends in place of the soft factory rubber bushings. Our kit replaces the factory links commonly referred to as the rear wishbone and rear guide links.BMW G8X Rear Upper Arms include gun drilled 6061-T6 Aluminum traction links to reduce weight, as well as a 6061-T6 Billet Aluminum curved rear upper camber arm that are Black Anodized to prevent corrosion and provide a durable finish. Our exclusive 360 degree 6061-T6 Aluminum Rotating Clamp design allows for quick, precise adjustment on the dogbone, while our curved upper arm utilizes our innovative double adjuster design that allows for easy and precise camber adjustment without removing the arm from the vehicle. Our Clamps tightened down with Blue Anodized Titanium Socket Head Cap Screws gives easy access to adjust camber settings, shaving off even more unsprung weight without compromising strength.This Part Fits:

Cool rock and roll jeans.
Size: 34, Color: Black
Very true to size jeans. I'm 6'1" 180. 34" waist is just a little loose. With a belt it's perfect. I'm usually a 32/33 so the sizing is right on.
