ST Sport Springs for BMW E90 sedan and coupe 2WD lower the vehicle slightly while matching the original dampers for consistent handling. Each kit is engineered with tuned spring rates to harmonize with factory shocks, made from chrome-silicon steel using cold winding and multi-tempering, and finished with an epoxy coating to resist corrosion and reduce sag for long-term improved driving dynamics.
