Eibach Pro-Kit Performance Springs (Set of 4) for BMW 6 Series 640i / 640d

With this Eibach Pro-Kit, you get a set of four performance lowering springs specifically made for your 2012-2017 BMW 640i or 640d. These springs are designed to lower your car's center of gravity, which helps reduce body roll when you're cornering and gives your BMW a more aggressive stance.

Eibach has been around for a long time, and they build these springs with a focus on performance without making the ride too harsh for daily driving. They use a cold-forming process and high-strength steel to ensure they hold up well over time. The goal here is to give you a noticeable improvement in how the car handles, making it feel more planted and responsive, while also giving it a sportier look with a lower ride height.

Installing these springs will change the way your 6 Series looks and feels on the road. It's a popular way to get that performance look and handling upgrade.
