Product Description

The SPL Parts SPL RTR E9X is a rear lower trailing arm upgrade for BMW E8X and E9X chassis, finished in anodized black and built to reduce the flex and deflection common to the factory rubber-bushed arms. This helps keep rear suspension geometry more consistent under hard acceleration, braking, and cornering.

As part of SPL's broader rear suspension lineup for the E8X/E9X platform, it's a solid choice for owners looking to firm up rear-end response. Confirm your exact submodel against SPL's fitment chart before ordering to make sure it matches your specific E8X or E9X configuration.
