The TEIN HIGH.TECH HT Spring Set (SKM70-BUB00) is engineered to lower your vehicle, providing a more aggressive stance and improved handling. This set is designed for the Mazda MAZDA6 models from 2003-2008, specifically the GG3P (FF) variant. These springs will lower the front of your vehicle by approximately 1.7 inches and the rear by 0.8 inches. They feature a spring rate of 4.3 kgf/mm for the front and 2.6 kgf/mm for the rear, offering a balance between ride comfort and sportier performance. The springs are constructed from Chrome-vanadium SAE9254V, a durable material known for its strength and resilience. It is recommended to use these springs in conjunction with OEM or similar shocks for optimal ride comfort and handling. The product is noted as "Not currently available to order" on some retail platforms, so verification of availability is advised before purchase.
