Epic Engineering springs are designed to give your Subaru a more aggressive stance, and increase the intensity of the driving experience while maintaining a smooth and comfortable ride. Epic Engineering spring kit lowers the car approximately 25mm in the front and slightly less in the rear giving the vehicle a slightly raked or "nose down" stance. This adjustment levels the wheel arches front to rear, for an aggressive and even look. The Epic STi kit features proprietary spring rates. The decrease in ride height effectively lowers the coefficient of gravity, as well as the front roll center and hence inclines the vehicle roll axis further up to the rear.
