This kit was designed to specifically address the issue of unnecessary mass within the factory front suspension. It helps to eliminate a considerable amount of weight relative to the factory steel parts they're replacing. Perfect fit, finish, and reliability!! Extensive street testing on our own daily-driven E63-AMG proved that these parts work flawlessly under any condition without any sacrifice.
We STRONGLY believe that you can't be serious about performance and / or efficiency if you don't recognize that weight (reduction) plays a major factor in both. It does make a difference, no matter how small the detail.
