BeastPower Motorsports now offers you this excellent solution for a chronic E39 problem:

BeastPower's E39 Sway Bar Brackets are custom designed for all BMW E39 5-Series models (from 1996 to 2003), including the M5.
The brackets offer peace of mind and additional safety when driving your 5-series to avoid the potentially drastic failure of the OEM sway bar brackets. There wasn't a quick fix for the 5-series (e39) rear sway bar bracket breakage problem, until now.

Meticulously designed and are manufactured to the highest specifications, each set of BeastPower Brackets are machined from solid blocks of very strong 6061-T6511 aircraft-grade aluminum, by CNC machine.

BeastPower Rear Sway Bar Brackets are sold in complete pairs (Both L&R)

Don't let this happen to you:

BeastPower Brackets carry a 10-year money back guarantee^* on the brackets against breakage (no matter what brand of rear sway bar is installed on your e39 5-Series). The breakage issue has been examined extensively in order to create the best possible design. Almost 1,000 BMW 5-series (e39) owners have already installed BeastPower Brackets on their BMWs over the past 6 years, and we believe that no 5-series (e39) should be without them.

Problems with Stock Brackets:

The primary issues with the OEM brackets relates to the weak aluminum that is used and the imperfect design:

• The OEM bracket is made of relatively weak stamped aluminum.
• The OEM design allows for too much movement of the bracket, causing it to swivel around the bolt. This causes the bracket to snap directly above the bolt.
• The upper lip bends easily due to the aluminum being too weak to support aftermarket rear sway bars. This bending can allow the bracket to pop out of the upper slot.
• The bolt digs into the lower bracket lip, a symptom related to the soft aluminum used in the OEM bracket. This thins the area around the bolt hole, weakens the metal, and thereby speeds-up the process which eventually causes the bracket to break.

Your suspension is a key system in your vehicle, and when a rear sway bar bracket breaks while driving, a potentially dangerous situation arises. Why take any chances, when you can have the best solution available.
