Bilstein has teamed up with Eibach to offer matched shock and spring packages. These Eibach springs are mated to a special set of Bilstein shocks to deliver a sporty and taut ride with as little impact on ride comfort as possible.

The Pro Kit uses an Eibach Pro Kit spring with Bilstein's Sport shocks and struts. Instead of taking parts from different manufacturers, Bilstein has tested the performance of the Eibach spring and tailored their shocks to be a true match for the new spring rate and ride height. This is known as a matched shock and spring and very few tuning companies take these extra steps. Eibach springs tend to be softer overall than most other aftermarket springs, which ensures the ride stays close to a stock comfort while still giving you a lowered stance and improved handling. 

Bilstein B12 Features: 

  • Precise response and excellent driving performance
  • Springs and shocks road tested and fine-tuned to complement one another
  • Bilstein Monotube/Inverted gas pressure technology
  • TUV certified
  • Made In Germany
  • Average Lowering of 25 to 40mm

Most cars don't need coil overs to improve their handling and bodyroll. For most drivers, simply replacing the shocks and springs with performance versions will meet their goals. If your shocks need replacing, and you felt the handling could be improved a little bit, this is an excellent performance suspension for you.
