For hobbyists restoring or racing older T Series cars, the XRAY 308397 spring set gives a firmer, more controlled ride. These medium-hard 1.8mm springs produce a 33 lb rate to help stabilise the chassis and sharpen turn-in on corners.
The firmer purple springs reduce excessive roll and improve weight transfer predictability, which helps drivers fine-tune balance on both carpet and asphalt. Colour coded for easy identification, they make setup swaps quicker during testing.
The XRAY 308397 spring set is a reliable choice for accurate suspension tuning on vintage T Series RC cars, delivering predictable performance for track days and practice sessions.
