E46 Ground Control Sway Bars

E46 Ground Control Sway Bars



We’ve Tried EVERY sway bar kit on the market. Every single one was either too long or too short in the front or rear or both! Most didn’t have the adjustments we wanted, So AAF teamed up with Ground Control to create the ultimate sway bar kit. These Sway Bars are the only hollow, tubular, fully-adjustable race bars on the market for your E46 M3 or E85/E86 Z4 M. The adjustments are fantastic, all of our drivers get exactly the ride that they want. They are also available separately to fit SCCA Super Stock autocross rules. These sway bars are made from a very lightweight tubular Chromoly steel and then zinc plated. The bars are mounted to the car with anodized CNC aluminum brackets, and they include urethane bushings with a grease fitting to keep the squeaks away.

The key feature of the front bar is the proprietary adjustment method – anodized CNC brackets slide on the bar and clamp down when in position, allowing infinite adjustment of the bar stiffness (front only).


Designed for Spec E46 class racing, this adjustable rear sway bar conforms to all of the current rules of the “Spec E46” racing class. Includes all necessary installation hardware and adjustable sway bar end links.

Like all other Ground Control parts, it comes with a lifetime warranty against all manufacturer defects.
