The Bilstein B6 Performance front strut insert is a high-quality replacement and performance upgrade for the BMW E30 325iX. It is designed to improve damping control while keeping the car comfortable enough for real street use.

Compared to a tired factory insert, the B6 helps reduce front-end float, brake dive, and vague steering feel. The result is a more composed front suspension that feels better during daily driving, backroad use, and spirited cornering.
