The reason these exist is straightforward: the G22 and G26 run a multi-link rear suspension with no factory camber adjustment built into the upper arm position. When you lower the car or push it on track, rear camber goes negative and stays there. The OEM arm is fixed length, so there is nothing to adjust at the alignment rack. These Godspeed arms replace that fixed arm with a threaded, length-adjustable unit with spherical bearing ends, which gives your alignment tech something to actually work with. The spherical bearings also eliminate the compliance you get with rubber bushing arms, meaning the camber setting you dial in at the alignment rack is the camber setting that stays there under load instead of shifting around through the corner.

Fitment Note: These rear upper camber arms cover all trim levels of the BMW 4 Series G22 Coupe, G23 Convertible, and G26 Gran Coupe across both RWD and xDrive AWD configurations. The G26 Gran Coupe platform also encompasses the fully electric BMW i4, which shares the same rear suspension architecture. These arms are not designed for vehicles equipped with air suspension or for vehicles running extreme negative camber associated with a stance setup. If your 4 Series has the optional Adaptive M Suspension or M Sport suspension, confirm with Godspeed before ordering as adaptive damper systems may affect installation.

Pairs well with:
- Rev9 Hyper Street II Coilovers for BMW 430i G22/G23/G26 RWD (2022-2024) Lowering the G22 platform shifts rear camber out of spec, which is exactly what these Godspeed arms are built to correct. Pairing coilovers with adjustable rear camber arms at the same time means you can get the car aligned properly right out of the gate instead of fighting geometry issues after the drop.
