Eibach's ERS line has evolved over the years to be the world's most prominent, comprehensive and superior Race Spring System. Eibach Race Springs are all manufactured in series production, often repeated, with a strong manufacturing experience. Thus, Eibach constantly achieves the most linear spring characteristic (rate) while maintaining the lowest tolerances and the highest quality in the industry.

The Eibach ERS Coil-Over Spring is engineered for demanding racing and performance applications where consistent spring behavior and precise suspension tuning are essential. Part number EIB0350.163.0140 is manufactured as part of Eibach's ERS race spring system, a comprehensive line developed to provide repeatable performance across a wide range of motorsport setups.

Each Eibach Race Spring is produced in series production using established manufacturing processes and extensive spring-making experience. This approach helps deliver a highly linear spring rate, tight manufacturing tolerances, and dependable quality from spring to spring. The result is predictable suspension response, allowing drivers and tuners to make accurate adjustments for handling balance, grip, and vehicle control.

Designed for coil-over suspension systems, this Eibach ERS spring features a 3.50-inch free length and a 1.63-inch inside diameter. Its 140-pound-per-inch spring rate is suited to applications requiring controlled suspension movement and repeatable damping characteristics.
