BMW Sway Bar Kits

Dinan sway bars are carefully engineered to match the driving dynamics of each BMW chassis. Dinan's research and development finds the ideal balance between improved handling while maintaining a comfortable ride. This set has been fine-tuned for the E39 chassis to reduce bodyroll, improve steering and turn-in response, and reduce understeer. Made of hollow tubular steel for light weight with adjustable ends to dial in the handling characteristics.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere. Each sway bar is worth 1 point towards your Dinan badge.

• 52% stiffer than the factory E90/E92 M3 bar. 42% stiffer than the E93 M3 bar!
• 27mm straight across (not a tapered center like the E93 M3 factory bar)
• Solid core, not hollow like the stock bars (better at resisting twist)
• Forged, non-adjustable steel ends
• Highest tensile steel strength available

The H&R for the E9X M3 is the best anti-roll bar option for the E9X M3. Don't be let down by the "small" size compared to the factory sway bar sizes - there are some big differences! We've had our in-house suspension engineers run the math and the H&R swaybar is over 52% stiffer than the factory E90/E92 M3 bar and even over 42% stiffer than the E93 M3 sway bar upgrade. There are several reasons for this - the stock sway bars are hollow (for lighter weight) and will twist more than the solid H&R bar. Also, the E93 M3 bar is often called a 28mm bar but it actually tapers down in the center to 24mm which greatly reduces its effectiveness. So if you're looking for a serious sway bar upgrade, the H&R is clearly the way to go. Note: to maintain the handling balance of the car, we recommend only using the front bar with the matching H&R rear bar or heavily revised racing suspension.

This bar re-uses the factory M3 sway bar bushings and brackets.

This item fits the following BMWs:
2011+ E82 BMW 1M Coupe
2008+ E90 BMW M3
2008+ E92 BMW M3

Dinan uses the factory sway bar with this new bracket and a 21mm rear sway bar to balance the M5/M6 handling. Instead of the traditional larger sway bar Dinan has come up with this way of stiffening the stock bar. This has a number of advantages over a thicker aftermarket bar: lower cost, the bar does not have to be removed, no tradeoff in ride comfort.

Dinan's research and development finds the ideal balance between improved handling while maintaining a comfortable ride. This set has been fine-tuned for the E90/E92 chassis to reduce bodyroll, improve steering and turn-in response, and reduce understeer. The front bar is hollow tubular steel for light weight with adjustable ends to dial in the handling characteristics. The rear bar is non-adjustable. These are the same sway bars used in Dinan's Stage 1 suspension and work best with Dinan shocks and springs or a similar sport suspension and wider rear tires.
