Part number eibPR1300.500.0175 is designed to help racing teams and performance enthusiasts fine-tune suspension dynamics across a wide range of vehicle setups. Its 175 lb\/in spring rate provides a precise foundation for optimizing chassis balance, grip, and rear suspension response.\u003c\/p\u003e\u003cp\u003eBuilt from high-tensile steel, the Eibach ERS Platinum spring combines lightweight construction with excellent durability. The spring is designed to maintain its dimensions and rate within exceptionally tight tolerances, lap after lap and race after race. Its block-resistant construction helps prevent loss of spring height, supporting consistent ride-height control and predictable suspension behavior throughout demanding motorsport use.\u003c\/p\u003e\u003cp\u003eThe flat-ground end configuration is manufactured with parallel tolerance to within plus or minus 1 degree for accurate seating and reliable load distribution. Compared with standard racing coil springs, the ERS Platinum design offers greater travel and deflection, giving tuners additional flexibility when configuring suspension performance. This individual motorsport spring is well suited for racing applications where repeatable response, accurate setup changes, and long-term consistency are essential. Verify vehicle, damper, perch, and suspension compatibility before installation.\u003c\/p\u003e\u003ch3\u003eProduct Specifications and Technical Data\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBrand: Eibach\u003c\/li\u003e\n\u003cli\u003eSeries: ERS Platinum\u003c\/li\u003e\n\u003cli\u003ePart Number: eibPR1300.500.0175\u003c\/li\u003e\n\u003cli\u003eApplication Position: Rear\u003c\/li\u003e\n\u003cli\u003eSpring Rate: 175 lb\/in\u003c\/li\u003e\n\u003cli\u003eOutside Diameter: 5.00 inches\u003c\/li\u003e\n\u003cli\u003eFree Length: 13 inches\u003c\/li\u003e\n\u003cli\u003eEnd Configuration: Flat-ground\u003c\/li\u003e\n\u003cli\u003eConstruction: High-tensile steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cp\u003eOne Eibach ERS Platinum individual motorsport rear spring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e Universal motorsport suspension component.
