SuperPro Alloy Front Control Arms & Radius/Thrust/Tension Strut Kit (Wishbones) for BMW 3 Series E90 E91 E92 E93 (E9x) inc M | Polyurethane Bushes, M3-Style, Adjustable Caster, +1° Camber | ALOY0090K

Alloy Front Wishbone and Tension Strut Upgrade for BMW E9x

Transform the front end of your BMW E90, E91, E92 or E93, including M models, with this premium aluminium wishbone and tension arm package. Designed as a direct bolt-on replacement for the factory front arms and soft rubber mounts, this kit delivers sharper steering response, improved straight-line stability, extra front-end grip and more consistent geometry under braking and cornering.

Built around SuperPro’s proven polyurethane technology, the bushes use a unique compound that resists deflection while maintaining road comfort. The result is fast-road and track-ready precision without unwanted noise, vibration or harshness. We fit these regularly for customers and on our own builds, and feedback is consistently excellent for both daily driving and spirited use.
