Spoon Progressive Spring - Civic FE1, Integra DE4

Using a normal damper, the height of the vehicle can be lowered, roll on winding roads can be suppressed, and both steering and safety can be improved accordingly. Lowers the car's center of gravity stiffens suspension for improved handling without sacrificing ride quality.

To keep the driving comfortable and still increase the spring rate, we chose the barrel spring. Unlike straight springs, these have multiple spring rates through them based on the difference in diameter. Having used the advantage of this shape, we came up with the suspension with the rate as low as 1G for your driving comfort, and higher rates for high-speed cornering and driving.

SPOON has developed a genuine shape spring with a normal ratio of about 25 mm down and a spring rate about 10% up. As the center of gravity lowers and the spring rate increases, the cornering performance improves dramatically, but since the thrust up feeling in the low speed range is set mildly, you can enjoy both winding and city riding.
