How to Do a Short Spring Retrofit

There is no problem in shortening the spring itself, but many friends did not consider the degree of cooperation between the shock absorber and the spring after shortening the spring. If you choose a spring that is much shorter than the original car, the shock tube will be compressed by a large stroke and the suspension will be soft. The reason why the suspension will be soft is because the shock absorber does not work between reasonable strokes. In this case, it is easy to cause the shock absorber to be scrapped in advance for a long time. This is also the main reason why many car owners have shock absorber damage after shortening the spring. one.

Short springs can lower the body, improve handling and aesthetics at the same time, and reduce the body's cornering roll, but it will affect certain passability and comfort.

The modification of the spring is mainly to improve the handling, that is, to switch to a harder spring or a shorter spring. Springs control many factors related to handling, and changes in springs can cause complex changes in handling characteristics. In terms of stiffness, the rolling resistance of the suspension can be improved and the rolling of the body during cornering can be reduced. The lowering of the car height can simultaneously lower the center of gravity of the body, reduce the transfer of body weight when cornering, and improve stability. And the reduction of the car height can also take into account the aesthetic effect.

The most important way to improve handling is to lower the body's center of gravity, which reduces weight transfer and body roll when cornering. The easiest way to lower the body is to use springs. Using short springs is the easiest and fastest method.

Car springs should be the most familiar accessories for refitting enthusiasts. For example, entry-level players who refit, most of them will choose to replace short springs to lower the body posture. One is to make the appearance more posture, and the other is to obtain better handling performance. Of course, the handling performance is definitely not as obvious as the coilover suspension and sports kit.

But this is also the first step for entry-level players. Short springs can increase the vehicle handling stability to a certain extent. At the same time, the price of short springs is much more affordable than that of twisted-tooth shock absorbers and pneumatic shock absorbers, so they are sought after by many entry-level modified car players.

The main purpose of our modification of the car spring is definitely to improve the handling, that is, to use a harder spring or a shorter spring. Springs control many factors related to handling, and changes in springs can cause complex changes in handling characteristics. With the increase in stiffness, the suspension's roll suppression capability is improved, and the body roll is reduced when cornering. The lowering of the car height can also lower the center of gravity of the body, which not only reduces the transfer of body weight during cornering, but also improves the stability, and the reduction of the body height also makes the appearance of the whole car more stance. However, the more effect of the short spring is to reduce the body height.

The thing to pay attention to when modifying the short spring is that it involves a "spring and shock absorber matching" problem. The reason why the automobile shock absorber assembly can make the vehicle run smoothly and ensure sufficient vibration filtering ability is the interaction between the working stroke of the coil spring and the stroke of the shock absorber movement.

If the height of the modified spring is much smaller than that of the original car, the telescopic stroke of the short spring will seriously limit the stroke of the shock absorber, resulting in that the shock absorber cannot work within a reasonable range of travel, the shock absorption effect cannot be exerted normally, and the shock absorption will be soft.

However, when the car is running at high speed, the stability is enhanced a lot. At the same time, when the car is cornering, the body roll is effectively reduced, and the cornering is faster. According to the principle of inertia, the sliding distance of the car is significantly longer than before the spring was not changed.

The main advantage of the short-spring shock absorber must be that the price is relatively affordable, and it is more friendly to the car owners who are just getting started. At the same time, the short-spring shock absorber is generally better than the original spring for the support of the body, and the lower ground clearance is also Makes the whole body look much better.
