The ST Racing Spring Package 40-250 is an additional racing spring kit for adapting the setup of an ST coilover kit. In the ST marking, 40 is the spring rate, the load in kg that compresses the spring by 10 mm, and 250 is the spring length in mm. ST marks it as a high-strength racing spring made from a material with higher load capacity. A higher rate gives a firmer, sportier setup and a shorter spring allows more lowering. No vehicle application is listed, so check the marking against the springs being replaced before ordering.
