Eibach ERS Platinum 20-Inch Rear Racing Spring, 3.50-Inch Outside Diameter, 70 lb/in – P2000.350.0070

Eibach PLATINUM series race springs are engineered using our proprietary ultra-high tensile strength steel, for the lowest physical weights and maximum spring travel. More Travel / Deflection than Standard Racing Coil Springs

• The Eibach ER Platinum Springs will Maintain Their Dimensions and Rates to Incredibly Tight Tolerances, Lap after Lap, Race after Race
• Flat-Ground End Configuration with Parallel Tolerance to +/-1 Degree
• Ultra Light-Weight Using High Tensile Steel
• Block Resistant - No Loss in Spring Height!

The Eibach ERS Platinum P2000.350.0070 rear racing spring is engineered for competitive motorsports applications that demand consistent performance, reduced weight, and reliable spring travel. Built from Eibach’s proprietary ultra-high tensile strength steel, this coil spring delivers a 70 lb/in spring rate while helping reduce unsprung weight and maintain predictable handling characteristics throughout extended track use.

Compared with standard racing coil springs, the Eibach Platinum series is designed to provide increased travel and deflection. The spring is manufactured to maintain its dimensions and spring rate within exceptionally tight tolerances, lap after lap and race after race. This consistency supports accurate suspension setup and repeatable vehicle behavior in demanding racing conditions.

• Feature: Platinum series construction uses ultra-high tensile strength steel for low weight and high durability.
• Feature: Increased travel and deflection help optimize suspension performance compared with standard racing coil springs.
• Feature: Flat-ground ends with parallel tolerances of plus or minus 1 degree promote stable spring seating.
• Feature: Block-resistant design helps prevent loss of spring height and supports consistent setup performance.
