In the first two articles, we explained the upgrade essentials of the travel system and frame reinforcement. The travel system upgrade frames the boundary range of future upgrades; The frame reinforcement lays the foundation for subsequent upgrades. Now that the goal of upgrading your car is clear and the foundation is solid, we can move on to the next step - the long-awaited suspension upgrade! Next, this article will introduce several different suspension upgrade ideas to you according to different needs!
Figure: Upgrading the suspension is indeed a more obvious operation in a number of chassis upgrade projects; After the suspension upgrade, both the comfort and handling of the vehicle will be greatly changed.
Keep it simple: just change the shock engine
Only change the shock absorber without changing the spring, the height of the body will not change, first of all, it will not affect the passability, the original can pass the hurdle, can be pressed on the shoulder can still pass; The second is not to worry about the change of suspension data, because by reducing the suspension height to reduce the body, it will cause the suspension swing arm to rise to a certain extent, although the small angle of the swing arm will not bring too much negative impact on the handling, but it is inevitable that there will be owners who are close to this, only upgrade the shock absorber will not have these troubles.
After replacing the shock absorber with better damping settings, the shock absorber can better pull the body and reduce the excess elastic vibration of the spring, and the driver will feel that the vehicle dynamics are more stable, and the car is more stable and comfortable to drive.
To sum up, only change the shock absorber this upgrade scheme, is the most **, the most in line with the upgrade needs of ordinary family users, if you happen to feel that the original suspension is not stable enough, want to improve the driving quality, and do not want to change too much of the original vehicle originally set by the owner, this scheme is the most suitable for you.
Figure: Especially for owners whose cars have been driven for several years and whose shock absorbers have been working abnormally, this scheme is more suitable; It also costs money to replace the original shock absorber or a third-party replacement shock absorber, and it also costs money to change a set of upgraded shock absorbers with better performance.
Limited budget: Replace the short spring
Upgrading the short spring can be said to be the lowest cost program in the suspension upgrade, only one or two thousand yuan, a set of international brand short springs have a deal, even if you add the cost of working hours, etc., that is, 3000 yuan will be basically finished, compared to the overall plan of tens of thousands of dollars, the money for a set of short springs can be said to be just a drop in the bucket.
Excluding the price, to put it simply, there are two advantages to changing the short spring: reducing the height of the car and changing the softness and hardness of the spring. Reducing the height of the car is very easy to understand, and the height of the car is naturally reduced when the spring is short; Reducing the vehicle height within a reasonable range and lowering the vehicle's center of gravity can reduce the vehicle's roll when cornering to a certain extent, which is a positive help to improve vehicle handling. Aftermarket upgrades tend to have better support for short springs, which hold up the car and reduce roll when cornering.
Here is another question that many riders will hearsay: will the replacement of the short spring reduce the life of the shock absorber, or will it cause oil leakage in the shock absorber?
Let's answer it in a unified way: First of all, there is no evidence or special test results to support the statement that "changing the short spring causes the shock absorber to accelerate aging"! The shock absorber is originally a consumable product in auto parts, even if it is placed in the warehouse for a few years, it will fail due to the deterioration of the shock oil, and if it is used normally, it will have to be replaced in about five years. Second, the vast majority of domestic drivers have a driving style of "not decelerating over speed bumps", and the shock absorber does not leak oil when used all year round? How durable is it? Before asking why the shock engine leaks oil, you may find the answer by asking yourself if your usual driving habits are correct. The last point, and the most critical point, learned from several domestic modification industry bigwigs: the cause of this questionable statement is not the summary of the use experience of the people, but the statement that some modification shops deliberately instilled to car lovers in order to sell the inventory twisted tooth shock absorber, so as to encourage those users who have difficulty in choosing.
According to the market data given by the two largest spring brands in the European automotive aftermarket, and the two companies that are competitors to each other, more than 70% of the users in Europe have changed the shock absorber and only replaced the sports short spring with the original shock absorber. It doesn't matter if you have patriotic feelings, but please respect the objective facts and reject hearsay.
Figure: Responsible manufacturers will consider special vehicles when designing short springs, and give special development plans according to the weight of different models and the characteristics of shock absorbers, so that the short springs can better cooperate with the work of designated models. Don't think that the development of this kind of sports spring is as simple as lowering it by tens of millimeters.
Consideration for street conditions: Sport package suspension
For a single-change shock absorber or a single-change short spring, the shock absorption performance will still be limited by the original parts, and it is impossible to achieve a qualitative leap; If you want to pursue a holistic solution, you need to replace the shock absorber and spring matching. If you're working on the streets, then the Sport Package suspension will be your first choice.
First of all, the sports package suspension still retains the same basic structure as the original suspension, with enough suspension stroke, and can cope with complex road conditions freely, and it is not easy to touch the bottom. Secondly, although the sports package suspension can provide stronger support, there is still room for comfort, and few sports package shocks will be adjusted to a rigid state, and there is no pressure to drive on the street every day. In addition, because the entire set of shocks is developed by the same manufacturer, manufacturers do not need to look ahead and backward when designing, and overly accommodate the characteristics of the original components, so the effect of the sports package suspension on the car is generally more obvious. Finally, the sports package suspension does not require a complicated tuning process, as long as it is installed correctly according to the manufacturer's requirements, it can work normally, saving time, worry and effort.
Figure: Of course, this type of product can at most allow users to adjust the damping of the shock absorber by themselves, and other parameters are basically fixed.
Choice for special use needs: twisted shock absorber
The twisted tooth suspension originally came from the track, and it is its inherent characteristics of many adjustable items, short strokes and strong support, even if some manufacturers later launched a relatively "comfortable" twisted tooth suspension, it is impossible to achieve the daily driving comfort similar to the sports package suspension. So before choosing the twisted tooth suspension, you have to ask yourself if you really have the ability and mental preparation to drive the car to the limit on the track. If it is mainly used on the street, why bother to choose the twisted tooth shock absorber, that is, lose the comfort, and can not play an upgrade effect?
If you do choose to upgrade the twist shock, then you need to understand the two categories of twist shock first. First of all, the most common is the full-length adjustable twisted shock, which is mostly found in Taiwanese brands and Japanese brands. The height of the full-length adjustable twisted tooth suspension and the spring preload can be adjusted separately, to put it bluntly, there is no direct relationship between the height of the suspension and whether the spring is tightened or not, and more personalized data can be made relatively when tuning.
Non-full-length adjustable twisted tooth shock absorbers mostly appear in European, American and Japanese brands, and the structure is slightly simpler than that of full-length adjustable, which also tests the research and development capabilities of manufacturers' special cars. Because of the development of the overall special car for the suspension, the actual effect of this twisted tooth suspension is generally better, of course, the cost is also higher. If you understand it in layman's terms, most of the non-full-length adjustable twisted suspension kits are developed for models, while a considerable part of the full-length adjustable suspension kits are developed for models with "different mounting positions", and the two are completely different levels of things in terms of research and development concepts. Therefore, have you ever seen a **twisted shock kit that costs 120,000, 20,000 or 30,000 yuan will be designed with a full-length adjustable design?
But no matter which one you choose, remember to find an experienced store to install and tune. If the manufacturer does not have enough professional knowledge and experience, no matter how good the twisted shock absorber is, it is better to change the shock absorber with a better set.
Upgrading the shock absorber pays attention to local conditions, what kind of needs to choose what kind of plan, everyone in the trouble before the purchase of the number of seats, on demand; Don't be quick for a while, because others say that the shock absorption is so good, so you grit your teeth and rush directly, and finally pass the speed bump to turn your teeth and scrape through the paint in the basement, only to regret it. Finally, I wish you all a good time on the upgrade road, if you want to know the detailed knowledge of the above upgrade schemes, welcome to visit [車誌carsmaga.com] search for related words, we have a more detailed article introduction, I hope to help everyone!
