AST Linear Race Springs - 180mm Length x 40 N/mm Rate x 61mm ID - Single

When you're setting up your suspension for track days or serious performance driving, the right spring rate is crucial for handling. These AST Linear Race Springs are built to give you a predictable and consistent response. The 40 N/mm rate offers a firm but manageable stiffness, suitable for many performance applications where you want improved body control without excessive harshness.

Measuring 180mm in length with a 61mm inner diameter, these springs are designed to fit many common coilover setups. Linear springs mean that as the spring compresses, the force increases proportionally. This predictable behavior helps your suspension work consistently through its travel, making it easier to fine-tune your car's handling for optimal performance on the track or spirited driving roads. They are a well-built component for anyone looking to dial in their suspension.
