AST Linear Race Springs - 130mm Length x 90 N/mm Rate x 61mm ID - Single

This is a single AST Linear Race Spring, measuring 130mm in length with a spring rate of 90 Newtons per millimeter and a 61mm inner diameter. These springs are designed for performance applications where precise suspension control is critical.

The linear spring design means that the force applied is directly proportional to the distance the spring is compressed. This predictable behavior is favored in racing and performance setups for consistent handling and feedback. The 90 N/mm rate offers a firm ride, suitable for track use or spirited driving where reduced body roll and improved responsiveness are desired. The 61mm inner diameter is a common size for many coilover systems, making it a versatile option for custom builds or replacements.

When selecting springs, consider the overall weight of your vehicle and your intended use. A higher spring rate like this one will stiffen the suspension, which can improve cornering but may also make the ride less comfortable on rough roads. Ensure this spring's dimensions and rate align with your specific coilover setup and performance goals.
