The BILSTEIN B6 and B8 high-performance dampers are the ideal solution for someone wanting to upgrade the handling of their vehicle. Made with the highest quality materials and manufactured at state of the art facilities in Germany, BILSTEIN B6/B8 high-performance dampers significantly increase performance and provide consistent damping over the life of the shock. The monotube gas pressure technology used in BILSTEIN dampers optimizes braking and tracking stability, thus ensuring dynamic and safe cornering. For those wanting to improve the handling of their FR-S or BRZ while retaining the factory springs, B6 dampers are the ideal choice. When lowering an FR-S or BRZ, BILSTEIN has a shorter, sportier version of the B6 called the B8. This shock is specifically designed for lowering and will work in conjunction with most aftermarket and factory lowering springs.
