What does the spring rate (12.0kgf/mm) mean for my car's handling?

A higher spring rate like 12.0kgf/mm means the spring is stiffer. This helps reduce body roll when you turn, making your car feel more stable and responsive in corners. It's a popular choice for those wanting a firmer ride.

What is the inside diameter and length of this spring?

This Cusco coil spring has an inside diameter of 65mm and a length of 180mm. These dimensions are important for ensuring it fits correctly onto your existing or new coilover shock bodies.

Does this spring come with any hardware?

This product is for the coil spring only. Any necessary hardware, such as spring perches or retainers, would typically be part of your existing coilover assembly or would need to be purchased separately.

About this part

Product Details

If you're rebuilding or upgrading your coilovers, a new spring is a key component to get the ride height and stiffness just right. This Cusco coil spring measures 65mm inside diameter and 180mm in length, offering a spring rate of 12.0kgf/mm. This rate provides a firmer feel compared to stock springs, which can improve handling by reducing body roll during cornering.

Cusco is known for making well-built suspension parts, and this spring is no exception. The 12.0kgf/mm rate is a popular choice for drivers looking for a noticeable improvement in their vehicle's responsiveness without going too stiff for daily driving. It's designed to fit coilovers that accept a 65mm ID spring, making it a direct replacement or upgrade option for many setups.
