  1. Great Quality Coilovers, perfect for anyone who daily drives there car aggresively

    By elijah March 16, 2018

    These are great coilovers for any road, to be honest a smoother ride then stock when setup correctly, go low enough to reduce the wheel gap to none and still have thread to go lower. They also handle great stay stiff enough I the turns while allowing you to keep control even if the suspension is disrupted by road hazards such potholes. Overall great product and would recommend them to anyone who enjoys driving.

  2. Worth every penny

    By James March 15, 2017

    These are fantastic. For anyone doing AutoX or time attack these are the perfect coilovers for you. They keep the car level and balanced. Their ability to absorb bumps in/on the road is next to none. Normal driving feels amazing after installing these as well. A must have for any aggressive driver.
