MAX IV GT Code No. 80230-AM001

▲The above photo is an item for CZ4A.

Awesome control and comfort ride on the street for a sporty drive. The new Max IV sporty suspension.

The Hipermax IV GT coilovers are designed and manufactured specifically for the Mitsubishi Evo X. This product is created to lower the vehicle’s ride height and stiffen the car’s suspension. A lower ride height lowers the center of gravity, which in turn, gives more traction at high speeds. A stiffer ride height aids in traction during cornering at high speeds.
