Enhance rear-end stability and precision with the Suspension Secrets Solid Rear Control Arm Bushes for the BMW G80/G81 M3 and G82/G83 M4. Designed to replace the OEM rubber bushings found in the inner mounting point of the rear upper control arm, these CNC-machined aluminium solid bushes significantly reduce flex and unwanted movement under load. By maintaining consistent suspension geometry during hard acceleration, cornering, and braking, they deliver a sharper and more predictable driving experience—ideal for spirited road use and track days alike. Finished in anodised black for added durability and corrosion resistance, these bushes are a direct-fit upgrade engineered to withstand the high demands of the G8X chassis.
