This kit does more than replace rubber. Its offset design moves the pivot point of the lower control arm to add positive caster and change how the front end resists dive under braking, which improves straight-line stability and turn-in feel.
Installation is rated moderate, with about 3 hours of work listed. Get the car aligned once it is back on the ground. Other Whiteline parts we list for the 440i Gran Coupe 4 Series: Adjustable Rear Sway Bar Link, Rear Subframe Mount Bushing, and Front Sway Bar Link Assembly.
Features

- Corrosion protection: Plated finish keeps rust off the hardware.

- Finish: The metal parts are powder coated for durability.
- Install guide: Instructions for fitting are packed in the box.
- Bushing compound: Oil, grease, ozone, and weather do not break down the synthetic elastomer used in the bushings.
