BMW E9X 335i/is NM ECS performance sway bars

The BMW E9X has proven itself to be a true-blooded BMW, with handling dynamics that are close to perfect.

One area of this particular model's suspension that can use bolstering is at the sway bar.

Gain aggressive driving dynamics in your E9Xs without extra noise, harshness, and vibration.

ECS tested 28mm front and 15mm rear sway bars for this precise reason.
Reduce body roll in turns, stiffen suspension, and add a much needed dimension of handling predictability with the ECS units - designed to fit and function in perfect harmony with your BMW.
