About this part

Product Details

If you're rebuilding your coilovers or looking to fine-tune your suspension setup for track use, these AST Linear Race Springs are a solid option. They offer a consistent spring rate throughout their travel, which is crucial for predictable handling when you're pushing your car hard. The 90 N/mm rate provides a noticeable increase in stiffness over stock, helping to reduce body roll and improve responsiveness during cornering.

These springs measure 100mm in length and have a 61mm inner diameter, making them compatible with many coilover systems that use this common sizing. AST is known for well-built suspension components, and these springs are made to handle the demands of racing and performance driving. Their linear design means that for every inch the spring compresses, it exerts the same amount of force, making suspension tuning more straightforward.
