Condor Speed Shop in collaboration with Snycro Design Works brings you the best rear trailing arm monoball bearing on the market. While at home on the street, this bearing is designed for track duty. Update and improve the rear suspension in your E36, E46, and Z4 by eliminating binding and deflection and increasing precision and longevity with these RTAMBs.

Why upgrade your rear trailing arm bushing to a bearing?
The trailing arm on the E36/E46/Z4 rear suspension attaches to the chassis just in front of the rear tire. The arm curves around the wheel, creating a pivot point which maintains toe-in as well as fixing the position of the wheels, front to rear. A stock rubber bushing wears over time, allowing deflection in the joint. The problem is compounded by performance upgrades such as increasing engine horsepower, increased grip of sticky tires, and improved braking systems. By maintaining precise control of the trailing arm, more aggressive alignment settings may be run, resulting in the car handling better without concern of 'rear steer' condition as a result of worn bushings. Our RTABS offer a range of multi-axial movement, where OEM bushings only pivot on a single axis, similar to a gate hinge in motion. OEM bushings, even when new, allow more deflection than preferred and have a limited service life

What makes Condor RTAMB’s worth the increased price point?
We use a high-quality OE developed monoball bearing, designed for long-life while offering full articulation for optimal suspension geometry. The bearings are lubricated and sealed for maintenance-free operation, which makes them the last RTAMB that vehicle will ever need. SDW's' own 410hp shop track/streetcar still has the original prototype bearing installed in 2009, with no measurable toe deflection. Condor RTAMBs are precision CNC machined and hard coat anodized to protect against corrosion, moisture, and salt spray. They come fully assembled ready to install.
