The difference between a strut and a normal shock is that a strut carries some of the weight of the car. Most of the time, the spring is mounted on the strut. In case of any compression on the strut, or the spring, or both, the wheel moves upwards towards the body of the car. The mechanism of the coilover is similar. It has a longer coil spring that is coiled around the strut. For the upward movement of the wheel, both the shock and the spring must compress. The spring carries the weight upon compression while the strut transfers or damps the bouncing to the spring. \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eIn the case of coilovers, you get what you pay.

Adjustable range (However, the lowest value may not be road legal. Even within the adjustable range, car body, arm etc. may contact. In such case, it will be hard to drive. Damper oil leakage or any other problems caused by low ride height setting from the factory setting will void the warranty of the product.) *4. Drivable range that there is no contact of car body or arms etc. (However, change of tire/wheel size may cause a problem.) Caution). Actual data depends on each vehicle.
