Product Details
AST is known for making well-built suspension components, and these Linear Race Springs are a solid option if you're looking to fine-tune your coilover setup. These springs are designed to provide a consistent spring rate throughout their travel, which is crucial for predictable handling on the track or during spirited driving. The 380 N/mm rate offers a firmer ride than stock, helping to reduce body roll and improve responsiveness when you're cornering hard.
With a 140mm length and a 61mm inner diameter, these springs are intended to fit specific coilover applications. The linear spring rate means that for every inch the spring is compressed, it resists with the same amount of force, making suspension tuning more straightforward. This consistency is what racers and performance enthusiasts look for when dialing in their suspension for optimal performance and feel.
