Please ensure your correct model is selected

Factory sway bars were designed to allow minimal body roll while maintaining a civilised level of comfort for day to day driving. When replacing them with a performance set, it is best to do both front and rear at the same time. These matched sets will change roll characteristics evenly from front to rear giving a predictable and balanced behavior.

As Used on Project E46 M3
The Turner Motorsport sway bar / swaybars for the E46 M3 were designed to provide better overall balance and performance than the stock anti-roll bars. With these bars you can greatly reduce bodyroll and decrease the understeering effects of a staggered wheel setup. They are adjustable in the front (3-position) and the rear (2-position) to fine tune the handling for both the street and the track. The Turner bars are sized at 30mm in the front and 25mm in the rear (+4 and +3.5mm from stock, respectively). We supply them with a urethane bushing with a reinforced inner core that requires no lubrication or maintenance so you won?t have to put up with annoying squeaks and annual greasing work. These bars are crafted from a special spring steel that is both stronger and more resilient than competitive sway bars. They have been shot peened and heat treated, and feature precision forged ends. We feel that these are the best bars on the market for the E46 M3 - we have used these on our race-winning M3s in the Koni Challenge and SCCA T2 classes.

Fitment
These bars fit in the stock locations using the original brackets and links. Our bar has been designed to use the stock M3 front sway bar links. Adjustable links are not required but recommended if the car is lowered or if you have coil overs. The rear hardware has been upgraded in our kit to a M10 sized bolt and it can be a little tricky to install on the factory end link. To avoid pre-loading the bar, it is best to leave one side un-done until the car is lowered to the ground. Never connect both links to the same bar with the car off the ground.

Do I need adjustable sway bar links?
The adjustable sway bar links ensure that there is no pre-load on the bar and that the bar has the correct clearance to other suspension components. Pre-load is when the bar is slightly stressed when it's on the car. If you have to force the links to fit the bar because it has tension then you have pre-load. Adjustable links fix all of that because you can then shorten or lengthen the link to match the installation of the bar. If you have coil overs or the car is very low, you should definitely have the adjustable links because these conditions may contribute to the pre-load situation. Adjustable front or rear links can be added from the options listed below.

Setup
The bars are adjustable so any driver can find an ideal setup for the type of driving they are doing. The sway bar becomes stiffer in the holes furthest from the end of the bar. The holes at the very end of the bar are the softest setting. We would generally recommend starting out with the front bar set to the stiffer setting and the rear bar positioned in the soft setting. Adjust to your liking from there.
