For racers tuning a Cobra GT8, the Serpent 600604 X-Hard Springs deliver a 42 lbs rate to help control roll and maintain composure on grippy surfaces. They provide a predictable, stiff baseline for further setup changes.
Made from high-grade spring steel, each spring is grinded flat, coated and hand-selected to ensure matched pairs and consistent rates across your shocks. This attention to detail supports repeatable lap times.
Although optimised for Cobra GT8 EP and GP models, these springs will fit a range of GT touring cars that accept the same spring dimensions, making them a practical upgrade for many hobbyists.
