Our MazdaSpeed3 Primo coilovers are height-adjustable from 2 to 4 inches below stock height. They offer higher spring and damping rates over the stock suspension to improve your MazdaSpeed3’s stability, grip, and look and include the ability to adjust the shock’s damping – all backed by the best, hassle-free lifetime warranty in the business and 30-day returns.
Please note that this kit requires the usage of your factory upper mounts. For some vehicles, installation of this coilover kit may require the use of wheel spacers to achieve proper wheel and tire clearance. Drop ranges are approximate. Actual drop range will depend on vehicle age, other modifications, and wheel/tire setup.
