ECS Performance Adjustable Coilover System - E9X (RWD) - With Installation Kit

The ECS BMW Coilover line was designed with our daily drivers in mind! Our focus was to improve the performance and look of the suspension, without forgoing ride comfort. Like many top-tier coilovers, these coilovers feel as smooth and comfortable as a stock setup, while also providing an aggressive look and vastly improved handling.

Our 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: 8kg/mm (front), 12kg/mm (rear)

PERFORMANCE FEATURES

• 32 levels of rebound damping adjustment
• Adjustable damping, monotube shocks/struts paired with optimized progressive rate coil springs give your vehicle road-sticking grip with reduced body roll for exceptional confidence in your vehicle's handling. With your vehicle's new, lower ride height, the center of gravity is now moved lower, further improving handling performance
• Adjustable front bodies allow you to set the ride height while maintaining correct spring pre-load
• Adjustable front and rear bodies allow the shock to operate in the correct valving range, regardless of ride height

PRODUCT DESIGN

• Strut and shock bodies finished with a durable gloss black powder coat for good looks and great longevity
• Threaded portions are clear zinc-coated for optimum corrosion protection against rain and salt
• Coil springs are powder-coated Reflex Silver Metallic finish for durability
• Red anodized, billet aluminum lower spring seats with locking collars allow for quick, on-the-car, adjustability with the included spanner wrenches
• Integrated bump stops
