Designed specifically for Legend and Midget racing applications, this spring helps optimize race-car dynamics by delivering a controlled, linear spring rate throughout its operating range. Its compact racing design supports maximum suspension travel while maintaining a small block height.\u003c\/p\u003e\u003cp\u003eBuilt from high-quality spring material, the Eibach ERS spring is individually tested to help ensure reliable rate accuracy and repeatable performance. Its lightweight construction helps reduce unsprung mass, allowing the suspension to respond more quickly to track surface changes. The 305 lb\/in spring rate provides a dependable foundation for fine-tuning chassis balance, cornering behavior, and overall vehicle response.\u003c\/p\u003e\u003cp\u003eThe Eibach EIB1000.188.0305 features a 10-inch free length, a 1.88-inch inside diameter, and a 305 lb\/in linear rate. It is intended for compatible coilover suspension systems and racing setups requiring an Eibach ERS main spring. Verify vehicle, coilover, and spring-seat compatibility before installation.
