Looking to improve your car's handling in the corners? ECS Tuning's rear non-adjustable sway bar is a cost-effective way to limit body roll and keep your wheels planted when entering a corner at higher speeds. Sway bars are a great way to improve handling without sacrificing ride quality or reliability! Sway bars are typically sold as a front and rear set to balance the handling. But a rear sway bar only can also have excellent benefits, especially on a street car. Going with a larger rear bar will improve steering and handling even at low-moderate speeds. ECS has specified a 15mm sway bar that has been fine-tuned for use on the E9X and E82 models. Urethane bushings with a reinforced inner core that requires no lubrication are included.

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.

Fits the following vehicle:
1997-2003 E39 BMW 525i 528i 530i 540i M5

Lowering your car is often the first step in suspension tuning, but occasionally, this process can adversely affect other associated components. Unwanted sway bar pre-load may be one of these consequential effects, adding asymmetrical spring rate bias to one side of the car versus the other. This imbalance may affect your overall chassis dynamics and corner balance. For this reason, adjustable sway bar end links are critical—by adjusting each link with the car at operating weight, you can ensure the sway bar is completely unloaded at your determined ride height, restoring your chassis' balance and your confidence in all driving situations. Unlike all other link kits on the market that utilize the cheaper and simpler jam-nuts, Fall-Line utilizes OE tie-rod end style pinch-nut fasteners to ensure they never lose their set length. NOTE: Installed photos show V1 jam-nut style V2 Key Features: Now includes OE tie-rod end style pinch-nut fastener rod ends Eliminates the typical jam-nut rod ends that are known to move over time Designed for superior corner balancing Ensures equal weight distribution on each tire Compatible with height adjustable dampers Eliminates uneven cross-weights Prevents sway bar-induced suspension stress Allows for precise customization through length variation Includes dust boots to protect against dust interference Made in USA Sold as a pair

Dinan has engineered this sway bar to work only with their Roll Control System to give the M5/M6 better balance in the corners.

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 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.

Dinan E60/E63 Sway Bar Specs:
R: 21mm, solid, 3-way adjustable, urethane bushings included

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.
