Part #: IS-PRO-Z33. After years of success with basic coilovers, ISR Performance has launched a high - end coilover line. These coilovers offer superior dampening control and overall performance, making them ideal for both street and track use. They provide a comfortable ride while enhancing handling. Key features include 32 - way adjustable dampening, a mono - tube design, a spring rate of 14K/12K, and front pillowball upper camber mounts. The ISR Pro Coilovers use high - end Japanese bearings. Our professional Formula D drift cars previously used the basic coilovers, and the Pro series is an upgrade. The package includes 2 front coilover assemblies, 2 rear coilover assemblies, 1 spanner wrench set, and 10 top hat lock nuts. Note: All ISR Performance products are designed for off - road use only.

Using your ISR Performance Pro Series Coilover Kit is easy. First, make sure your vehicle is on a flat and stable surface. Then, carefully install the 2 front and 2 rear coilover assemblies according to the instructions. Use the spanner wrench set to adjust the coilovers as needed. You can adjust the dampening in 32 different ways to suit your driving style, whether you're on the street or the track. When it comes to maintenance, regularly check the top hat lock nuts to ensure they are tight. Also, keep an eye on the Japanese bearings. If you notice any unusual noises or a change in performance, it might be time to have them inspected. Remember, this product is designed for off - road use only, so don't use it on public roads to avoid potential issues.
