Description

The Scale Suspension MZ18-IS is a fully adjustable and customizable coilover suspension upgrade designed specifically for the Mazda 3 2019-2023 models. This innovative series coilover system aims to achieve a perfect balance between street comfort and enhanced performance. It allows for easy adjustment of your vehicle's ride height while significantly improving its handling capabilities. The unique patented scaled system design ensures easier and more precise adjustments, guaranteeing equal height on all corners. Each coilover shock features 24 distinct levels of dampening adjustment, allowing you to fine-tune the valving for optimal performance. The MZ18-IS coilovers are handcrafted and assembled to customer specifications at SCALE facilities. The front Macpherson configuration includes adjustable camber plate front top mounts, enabling you to set your desired camber specs and prevent excessive tire wear. A gravitational bearing option is recommended to reduce the effort required for camber plate adjustment. The rear axle beam configuration is designed such that wheel alignment is not affected when lowering the car, meaning no additional camber will result from setting your desired ride height, and no adjustment parts are needed for the rear. Scale Suspension also offers customization of spring rates and shock lengths to meet exact application needs. The assembly requires no welding and the units are rebuildable.
