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.

To reduce the understeering affects of a staggered wheel setup you want a balanced set of sway bars. ECS has configured this anti-roll bar set for the non-M E46 with a 27mm adjustable front bar and a 21mm rear bar. The front is adjustable to two positions to fine-tune the handling and reduce understeer. The rear bar is fixed to retain the stock sway bar link. These anti-roll bars include urethane bushings with a reinforced inner liner that eliminates squeaks and doesn't require lubrication. The bars are powder coated for durability and good looks.

These bars fit in the stock locations using the existing brackets and links. Adjustable links are not required but recommended if the car is lowered or if you have coil overs (note: the rear bar is designed to only use the stock link, heavily lowered cars should not use this kit).

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 hole(s) 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 adjust to your liking from there.

Hotchkis Sport Suspension products have been developed with strength, reliability, fitment, appearance, and durability all factored into their products to ensure that customers are never left unsatisfied.

Performance sway bars allow you to take corners aggressively while still keeping the wheels firmly planted and reducing body roll, all without reducing overall ride quality. Hotchkis sway bars feature powder coated tubular steel construction for maximum durability and stiffness.

As Used on Project E46 330 To reduce the understeering affects of a staggered wheel setup you want a balanced set of sway bars. We use a 2-way adjustable 27mm front bar and a 3-way adjustable, 21mm rear bar. These anti-roll bars have precision forged ends and include urethane bushings with a reinforced inner liner that eliminates squeaks and doesn't require lubrication. The bars are powder coated for durability and good looks. These bars are made from a proprietary alloy that is both stronger and more resilient than other sway bar kits.

Fitment
These bars fit in the stock locations using the existing brackets and links. Adjustable links are not required but recommended if the car is lowered or if you have coil overs. We can also include new factory links with the hardware pressed in for a quicker install. This is especially helpful in the rear where the hardware can be tricky. 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.

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 middle. Adjust to your liking from there.
