New MEDIUM-HARD progressive springs have medium firmness at the beginning of the compression but become firmer as the spring is compressed more in the middle, with hard firmness at the end. Marked with FOUR stripes for easy identification.Ultimate high-performance racing springs give you additional precision tuning options for your XRAY model racing car. Developed through extensive testing and racing experience, these racing springs were designed and precision-crafted to have a more progressive rate than standard XRAY racing springs. As the car enters the corner, the spring has medium firmness to generate medium grip, but as soon the car inclines the springs achieve a hard firmness to achieve a higher cornering speed.Available as a pair of springs, the springs are individually measured, controlled, inspected and matched to provide identical damping characteristics. During the selection process, each spring is compressed in several fine increments and the values recorded, and then each spring is matched with another spring of identical characteristics. XRAY goes the extra mile to ensure perfect spring matches, giving your car the predictability and consistency that you need to help you lead the pack.Medium-hard progressive springsBetter steering at corner entryFor high traction tracksMarked with FOUR stripes for easy identificationIndividually measured and controlledIndividually inspected and matchedFits: XB808, XB9 cars, XB8 and XB8E (front & rear)
