Coilover Springs
Coilover springs are the replaceable compression springs that wrap around the shock body in a coilover assembly, determining ride height, spring rate, and the balance between comfort and handling stiffness. Swapping springs is the most direct way to tune a coilover setup for a new application without buying an entirely new system.Popular UpgradesLinear-rate springs in the 6 to 12 kg/mm range are the most popular choice for street performance and track day builds where predictable handling is more important than maximum compliance. Progressive-rate springs that soften on small bumps and stiffen under load are preferred for street cars that need to be both comfortable on rough roads and controlled in hard cornering. ID60 and ID65 springs are the most common inner diameter specifications across popular coilover platforms.What is the difference between linear and progressive coilover springs?A linear spring has a constant rate from full droop to full compression, providing consistent an...
