BMW Sway Bar Kits for BMW Z Series E85/6 (2003-2008)

Clear BMW chassis

Please ensure your correct model is selected

The next step in tuning your car's handling - after shocks/springs and camber plates - should be a set of swaybars. Using larger front and rear sway bars will give your car better/quicker turn-in and less bodyroll in corners. These bars replace the existing sway bars on the car for a clean and simple upgrade with very little downside. Sway bars should be matched with your springs/shocks to maintain a proper handling balance. In some cases only a front or rear bar is needed to positively change the balance and make the car more neutral. We sell sway bar kits from H&R, Racing Dynamics, OE BMW upgrades, and even some of our own designs. Swaybars are sold with new bushings. New links and other hardware are strongly recommended.

Our renowned TMS adjustable front sway bar / swaybar links for BMWs are now available in custom lengths, making them easy to order for any aftermarket or custom suspension setups. Simply measure for your ideal link length, and order the links with the best length range (below). Each sway bar link has a 10mm diameter mounting pin/stud, which is the typical factory/stock size for a universal fitment. These are sold by the pair, and each set includes two matching sway bar end links.

These end links offer the quiet operation and long life of "stock" BMW end links, but with the strength and adjustability of rod-end style sway bar links. These sway bar links can be used on a wide variety of BMWs and aftermarket BMW suspensions. When measuring, please consider that the length ranges of our Custom Adjustable end links are measured from the center to center on the end link mounting stud / pin, as shown in our diagram.

Note for E9X M3: the unique mounting on the M3 strut requires a set of our adapter seats (#TSU9912AF9). You can add them with your links from the menu below.

You get the best of both worlds with this pair of Turner Motorsport adjustable sway bar links. We searched far and wide to find the hidden gem of swaybar links. You get the same quiet operation and long life as the stock links plus the strength and adjustability of rod-end style sway bar links.

With the wide range of suspensions and sway bars available today adjustable sway bar links can help you with many problems. Along with the ability to remove preload you can change the length to maximize sway bar geometry. Example: if the sway bar hoop comes too close to the steering rack, oil cooler, or under tray in its suspension travel you can adjust it by simply lengthening or shorting the adjustment rod. In some cases you may need a longer or shorter adjustment rod to achieve optimal geometry. We also offer these same links in other custom lengths (click here) that may not be specific to BMW chassis.

Features:

  • Adjustable to neutralize preload on sway bar (balanced handling)
  • The ability to set sway bar geometry and clearance
  • Low friction ball joints
  • High articulation
  • Direct replacement for OEM sway bar links
  • Watertight boot seal
  • Ball joint is made by a world leader in ball joint technology, THK. THK's OEM Customers: BMW, Porsche, Ford, GM, Nissan, Honda, and Toyota

    This single swaybar link is adjustable to eliminate preload on the front sway bar in E30 M3, E36 M3, E46, and Z4 models. Preload is tension on the bar when the car is at rest on the ground. Ideally, the bar should be neutral with zero tension on both ends (no twist in the bar at rest). Preload comes from inconsistent side-side ride height (such as with coil overs), a bent swaybar, a bent strut housing, or a chassis with bent or skewed frame rails. The handling is affected with a preloaded sway bar so removing that tension will give you more consistent handling and response. Preloading can also lead to premature failure of the link ball joints.

    To remove preload you only need an adjustable link on one side of the car. Install your stock swaybar link on one side, lower the car to the ground, adjust the Turner link to meet the swaybar hole on the other side, and tighten everything up. Never install both sway bar links with the tires off the ground. Our link is made from a stock HD swaybar link with an easily adjusted hex rod in the middle.

    One link or two? Technically, the remove preload only one link is required. However, there may be cases where having two links is better. Having an adjustable link on both sides of the car will allow you to better position the front sway bar for clearance or when a different racing style coil over is used.
