Millway Upper Rear Arm BMW M3 E92 E90

On track, when cornering loads increase lateral forces, the stock rubber bushings are known to flex, compress and cause deviations in the geometry.

This creates a feeling of instability and blurs your perception of how the rear end is behaving. In this case there is only one solution: stiffen it with spherical bearings.

These parts, designed and made by Millway in Sweden, correct these shortcomings with classic but proven choices:

• Light and strong materials (anodised 7075-T6 aerospace aluminium)
• Motorsport-quality spherical bearings
• weight optimisation

Team Lupos's take:

If you don't do track driving, this type of part will be of little use, since you cannot load the suspension on the open road the way you do on track; it will add extra noise and vibration transmitted through the chassis. Sport bushing-type solutions will be more appropriate (but too fragile on circuit)
