Bilstein Technology Overview

Bilstein performance systems typically use:

• Monotube gas-pressure dampers → better heat control, sharper response

• Precision valving → chassis-specific tuning

• Threaded coilover bodies on B14/B16/EVO → fine ride height adjustment

• High corrosion protection coatings → especially in the EVO series
