What is the typical lowering amount for this kit?

This Bilstein B12 Pro-Kit is designed to provide a moderate lowering of your vehicle, typically between 25-40mm. The exact amount can vary slightly depending on the specific BMW X3 or X4 model and its original ride height.

Does this kit include everything needed for installation?

This is a complete front and rear suspension kit, including Bilstein dampers and Eibach springs. It is recommended to consult the manufacturer's installation instructions for any additional hardware or components that may be required for a proper installation.

How does the progressive spring rate affect ride quality?

The progressive spring rate means the springs are softer during normal driving, offering a more comfortable ride. As the suspension compresses further during cornering or over bumps, the spring rate increases, providing better control and reducing body roll for improved handling dynamics.

About this part

Product Details

Bilstein is well-known for their high-performance dampers, and this B12 Pro-Kit suspension kit brings that expertise to your 2011-2017 BMW X3 or 2015-2018 BMW X4. This isn't just a set of shocks and springs; it's a carefully matched system designed to give you a noticeable improvement in how your vehicle handles, along with a sportier stance. If you're looking to get more out of your BMW's suspension, this kit is a solid option.

What makes this kit special is the synergy between the Bilstein B8 Performance Plus dampers and the Eibach Pro-Kit springs. Bilstein tunes these dampers specifically to work with the progressive rate Eibach springs included in the kit. This means they're designed to control the spring's motion effectively, leading to more predictable handling, especially during spirited driving or when cornering. The result is a more connected feel to the road, with improved responsiveness and a significant reduction in body roll. The kit is engineered to provide a moderate lowering of your vehicle, typically between 25-40mm, which not only enhances the look but also lowers the center of gravity for better dynamic performance.

This is a complete front and rear suspension kit, meaning you get everything needed to upgrade all four corners of your vehicle. The springs have progressive characteristics, which allows for a comfortable ride during normal driving but stiffens up as needed during harder cornering or over bumps. This balanced approach offers a great combination of everyday comfort and sporty performance, making it a popular choice for drivers who want a more engaging driving experience without sacrificing too much ride quality.
