— Sway bars (a.k.a. anti-roll kits) offer the greatest improvement in handling for the dollar. Watch Otto install a set of pre-tuned Bavarian Autosport sway bars on a BMW E46 (3 series 99 thru 05). He installs the front bar in Part 1, and the rear bar in Part 2.
These bars work with the original BMW end links, so installation is straightforward and cost-effective. You can purchase Bavarian Autosport sway bars in our online store at
