This 29mm front sway bar is from the E64 M6 cabrio but is a direct fitment upgrade on other E60 5-series and E63 6-series models with new bushings and hardware. We put this kit together that includes everything you need.
Will not fit cars with Dynamic Drive (aka Roll Control, Active Sway Bar).
This kit includes:
1 x 31352283123, 29mm front sway bar
2 x PFF5-703-29, Powerflex 29mm urethane sway bar bushings
2 x front sway bar bracket reinforcements
2 x 31356763094, M8 square nut
2 x 31356765194, M8x35 hex screw with flange
2 x 31316769731, M8 hex nut with flange
Adding a larger front sway bar adds stability and improves steering to the front suspension on E60 525i, 528i, 530i, 535i, 545i, 550i, M5* and E63 645ci, 650i, and M6*. Stock bars on these other cars are 25-28mm, which makes this 29mm bar an upgrade for all RWD E60, E63 models. Even a 1mm difference makes a noticeable change. You'll notice the steering reacts quicker and faster and with less bodyroll in the front. A rear bar is recommended but is not required.
We used Powerflex urethane bushings in this kit because they are the proper 29mm inside diameter. The factory BMW bushing is actually 28mm. The stiffer urethane will also improve sway bar performance and they have a lifetime warranty.
All other parts are Genuine BMW, which makes this a direct install even for E64 M6 cabrio. You can use your original front sway bar links or add new Meyle HD links too.
* - this package is intended for non-M models and you can re-use the original sway bar bushing bracket with the Powerflex bushings. For M5/M6 models you will need to buy the non-M bushing brackets that work with these bushings (BMW part #31356757099, see Related Items below).
