Designed for competition vehicles, this spring helps optimize handling dynamics by providing consistent performance, controlled movement, and reliable load support. Its conventional design is well suited for race setups that require carefully selected spring characteristics for shocks, pull-bars, and other suspension systems.\u003c\/p\u003e\u003cp\u003eEibach Part EIB1100.500.0450 is manufactured with precision tolerances to support repeatable suspension performance and accurate setup changes. The spring is designed to minimize side loads while keeping the load center ideally positioned in relation to the spring axis. This promotes smooth operation and helps maintain predictable suspension behavior under demanding track conditions. Its lightweight construction also helps reduce unsprung mass, supporting improved responsiveness and tire control.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e One Eibach ERS conventional rear spring.
