Rear Control Arm for BMW 1 Series E82 (2008-2013)

The rear lower control arms on E82/E9X models are the weakest link in the rear suspension. The arm is made from folded sheetmetal and it bends and deforms easily. Not only will it deform from potholes and curbs, tow truck drivers love to hook onto them without realizing how weak they are. We have seen other race teams complete the box section to make them stronger. A bent arm will throw off the geometry in the suspension, potentially affecting handling and tire wear. These aluminum arms are both lighter and stronger than the factory sheetmetal arms and is the best solution for chronic bending of the stock arm. These are a direct replacement to your stock arms with no changes needed to your alignment. New high-grade hardware is included.

Note: the stock arm is designed from the factory to be intentionally weak. These arms will bend so that something else in the suspension does not break. Our race cars used the stock sheetmetal arm but we replaced them often. We found that it was better to finish a race with a bent arm than not finish due to a catastrophic failure. The ECS arms are still designed to be the weakest link but are far stronger than the factory arm and will not bend as easily.

When an E9X is lowered beyond the limits of just lowering springs, the rear wheels toe-in excessively. This excessive rear toe leads to premature wear, that many people attribute to an increase in negative camber. It has become a common belief that an extremely low vehicle will wear the tires wrong as a matter of consequence. It has become standard practice to go as low as you can and proceed to replace your tires every five to ten thousand miles. Whats more is that when the vehicle reaches a certain ride height, the factory arms become maxed out and there is no way to compensate and dial in the proper toe. You're left with an improperly aligned vehicle that is in effect worse off than it was with the stock suspension installed.

This is not only uneconomical but improper and unsafe. ECS Tuning is proud to offer a solution for this problem in the form of Rogue Engineering E9X adjustable rear toe arms. These arms allow for greater toe adjustment on vehicles that have been lowered with a coilover suspension. With the toe set properly the tires can contact the road properly this maximizes grip and minimizes wear. 

Features:

• 100% machined and anodized, 6061-T6 lightweight aluminum arms
• High-strength, 3-piece, rod end (with carbon fiber reinforced, PTFE race) offers longer life for street compared to standard rod ends
• SEALS-IT Rod end seals keep dirt, water, and other contaminants out
• Rod ends feature grease fittings, to allow for rod end serviceability.
• Lighter than stock!  (Stock is 875g, RE arms are 640g)
• Extremely easy installation and adjustment (your alignment shop will LOVE you!)
