SuperPro 2012 BMW 328i Base Front Alloy Control Arm & Radius Arm Kit

Starting with the M-style lower control arm featuring a fixed camber increase and a heim-style bushing, this SuperPro kit is built for performance. This isn't just a replacement part; it's an upgrade designed to give you more control and feedback from your BMW's front end. The OEM rubber bushings are replaced with SuperPro's own, which significantly reduce arm movement. This translates to a more stable feel during hard braking and cornering, and can even help increase tire life by keeping them planted more consistently.

The radius arms in this kit are where you can really dial in your alignment. They're designed for on-car adjustment, allowing you to add or decrease caster by up to 0.8 degrees on each side independently. This is a powerful tool for correcting a slight pull, enhancing directional stability, or maximizing positive caster for improved grip and a more connected steering feel. The kit includes a spanner tool specifically for adjusting these radius arms, and it's designed to fit subframe mounts that are 95mm wide. This complete kit replaces both the front radius and lower control arms, and includes all necessary SuperPro bushings and ball joints for a full upgrade.

This SuperPro kit is a complete replacement for your BMW's front radius and lower control arms, offering a significant upgrade in handling and steering response. It's designed to fit a wide range of BMW F20, F21, F22, F30, F31, F34, and F35 chassis models, including popular examples like the 2014-2016 BMW 228i, 2013-2018 BMW 320i, and 2012-2016 BMW 328i. While it enhances performance, the SuperPro bushings are engineered to allow full articulation without binding, and importantly, without introducing unwanted noise, vibration, or harshness into the cabin. This means you get improved handling and a more direct feel without sacrificing ride comfort.
