ECS Performance Adjustable Coilover System - E9X RWD - With Installation Kit
This brand new BMW Coilover line from ECS Tuning was designed with daily drivers in mind! Their focus was to improve on the performance and look of the suspension, without forgoing any comfort. Like many of the top tier coilovers, these coilovers feel as smooth and comfortable as a stock setup, while giving you an aggressive look and vastly improved handling, all at a fraction of the price!
The ECS Tuning Performance Coilover System provides a sport-tuned, height, damping, and body adjustable suspension with substantial performance benefits using high-quality materials and coatings to replace your worn suspension, all while giving your vehicle that perfect ride height!
Spring Rates: Front is 8kg/mm, Rear is 12kg/mm
PERFORMANCE FEATURES
