The XRAY 308398 Red Hard Spring Set delivers a 38 lb rate in a 1.9 diameter coil aimed at older T Series platforms. These springs stiffen the chassis and sharpen steering response, which helps when recovering mid-corner or pushing pace on uneven surfaces. The red finish identifies the hard specification for quick selection during setup changes.
A practical upgrade for builders and racers refining handling on classic T Series cars, giving clear tuning feedback.
