Our Subaru WRX STI 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 STI’s stability, grip, and look. Additional adjustments include camber and independent spring pre-load and the ability to adjust the shock’s damping – all backed by the best, hassle-free lifetime warranty in the business and 30-day returns.
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.
