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

Need hardware? Take the guesswork out of your install with our carefully curated installation kit! This vehicle-specific kit includes the proper nuts, bolts, washers, and gaskets required for a comprehensive installation: T#48815455

PERFORMANCE FEATURES

32 levels of rebound damping adjustment
Adjustable damping, monotube shocks/struts paired with optimized progressive rate coil springs gives 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 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

PRODUCT DEVELOPMENT

In-house designed to give your vehicle superior handling performance, long term corrosion protection and fully adjustable ride-height, we set out for a coilover system that is made for THE enthusiasts! Installed and evaluated in-house by our Product Development team in our Wadsworth, Ohio facility, we ensured a high level of precision and quality is delivered throughout thousands of miles of long term product testing.
