Improve rear suspension adjustability and handling performance with IRP adjustable rear control arms, designed for BMW E8x and E9x models, including M1 and M3 models. These control arms replace the OE rear lower control arms, allowing for precise camber and toe adjustment—which is crucial for lowered vehicles, track and drift setups—and improves overall chassis balance.
These adjustable control arms are made of lightweight yet highly strong aluminum and provide greater stiffness and reduced unsprung mass, resulting in better suspension response and more predictable handling dynamics.
High-quality, CNC-machined aluminum construction
Fully adjustable geometry for ideal rear camber and toe alignment
Improves grip, directional stability, and cornering performance
Perfect for street performance, track days, drifting, and competition use
Compatible with all BMW E8x and E9x models, including the 1M and M3 variants
