Hotchkis 99+ E46 BMW M3 Rear Swaybar

If you're looking to sharpen the handling on your 1999-2006 BMW M3, this rear sport sway bar kit from Hotchkis is a solid option. The stock M3 often struggles with noticeable understeer and limited body control during spirited driving. This kit is designed to directly address those issues by increasing the stiffness of the rear suspension, which helps the car rotate more easily into corners and allows for better throttle steering.

This sway bar is constructed from lightweight 1-inch (25mm) tubular steel and features a durable powder coat finish for long-term protection. What's really neat is that it offers two distinct stiffness settings, allowing you to dial in the rear roll stiffness to be either 79% or 105% stiffer than the factory bar. This adjustability, combined with the included performance rear end links and greasable bushings, gives you a lot of tuning capability to achieve a more neutral and responsive feel. You'll notice a significant change in turn-in response and overall balance.

This package comes complete with everything you need to install the sway bar and end links. By reducing understeer and improving roll control, this Hotchkis sway bar kit helps transform the M3's handling characteristics, making it feel more neutral and predictable when you're pushing it.
