AST Linear Race Springs - 180mm Length x 70 N/mm Rate x 61mm ID - Single

Starting with a 70 N/mm spring rate and a 180mm length, these AST Linear Race Springs are built for performance applications where precise suspension control is key. The 61mm inner diameter is a common size for many performance coilovers, making them a versatile choice for builders looking to fine-tune their setup. These springs are designed to provide a consistent force throughout their compression range, which helps maintain predictable handling characteristics under demanding driving conditions.

Crafted from high-tensile steel, these springs are made to withstand the rigors of track use and spirited driving. The linear rate means that for every millimeter the spring is compressed, it exerts the same amount of force, offering a straightforward way to understand and adjust your suspension's behavior. This predictability is crucial for setting up a vehicle that feels responsive and stable, whether you're cornering hard or navigating uneven surfaces.

When considering a spring swap, remember that changing spring rates can affect other suspension components. It's often a good idea to consult with a suspension specialist or refer to your coilover manufacturer's recommendations to ensure compatibility and achieve the desired handling balance for your specific vehicle and driving style.
