Millway Motorsport Billet Rear Trailing Arms BMW E9X M3/E82 1M
Product Description
The Millway Motorsport Billet Rear Trailing Arms for the BMW E9X M3 and E82 1M are lightweight, high-stiffness rear suspension upgrades designed to replace the original steel trailing arms.
Manufactured from billet aluminium, each arm weighs only 430 grams, offering significant weight savings over the OEM component. This reduction in weight helps improve suspension response, agility and overall handling precision.
The rigid aluminium construction increases rear suspension stiffness, giving the car a more direct and controlled feel under load. This is especially useful for performance road driving, track use and high-grip suspension setups where consistent rear-end behaviour is important.
Designed as a direct replacement for BMW part number 33322406291, these billet rear trailing arms are supplied as a pair and provide a durable, lightweight solution for E90 M3, E92 M3 and E82 1M owners wanting improved rear suspension response.
