About this part

Product Details

AST is known for making high-performance suspension components, and these linear race springs are a solid option for anyone building or rebuilding a coilover setup. This particular spring offers a 75 N/mm spring rate, which is a good middle ground for track-focused vehicles that still need some compliance on the street. The 300mm length and 61mm inner diameter are common dimensions, making them compatible with many coilover bodies.

These springs are designed for consistent performance. The linear rate means that as the spring is compressed, the force increases at a steady rate, which is predictable for tuning suspension behavior. This makes it easier to dial in your car's handling for specific track conditions or driving styles. They are well-built to handle the stresses of racing and spirited driving.
