Car companies are targeting models for family use, such as Toyota Corolla. In the factory state, it can cope with a variety of complex urban and suburban commuting road conditions, so that the car has a certain road passability and ride comfort, and generally pre-installed a set of suspension spring groups with longer travel and softer damping settings. Although we know what the intentions of the car companies are, this higher center of gravity of the body will indeed allow the vehicle to bring greater lateral movement inertia when driving at high speed or performing the driver's emergency avoidance behavior, which is simply "unstable down". The instability of the lower plate and the large action of emergency avoidance can easily lead to the loss of control of the car after avoidance, and we can see many traffic accident cases.
I believe that all readers have understood the basic requirements for practicing martial arts, and they should know that "stability in the lower plate" is the most basic, and it is also a good basic skill before learning martial arts. The same is true for the car, when the lower plate is stable, it can allow the driver to carry out greater control without easily losing controlSuspension tube grip efficiency, shock tube support reaction speedOnly when the two cooperate well with each other is the core priority of the next stability. There are many ways to steadily improve the ability of the vehicle to go down, but there are also some ways that may have a certain impact on the annual review of the vehicle, but the topic to be developed today is to improve the driving stability of the vehicle without affecting the condition of the car inspection, one of the ways is to replace the short spring for the Toyota 12th generation Corolla (E210) without changing the original shock absorber.
Short spring Sport spring is a spring set for OE type, that is, the original style shock absorber, and the short spring is generally manufactured in the form of variable diameter. The so-called reducer is actually based on the compression degree of the spring, its stiffness will change accordingly, and the support for the body will also be improved, which is why the reducer spring will not be marked with a fixed K value like a straight coil spring. The short springs do not affect the work of the original shock engine while lowering the vehicle's center of gravity and increasing support through a shorter stroke, as well as a slightly higher stiffness than *** springs.
As for the brand, by the way, I will bring you a trick for riders: if you want to know whether a certain suspension brand you like is a professional manufacturer, in fact, see if they have a sports spring product line, if not, it is not necessarily not a professional brand of a large factory;If there is, it must be a large manufacturer, and it is a professional shock absorber manufacturer.
godspeed
Godspeed, a well-known manufacturer of automobile suspension and chassis components from the United States, has launched a suitable short spring product for the 12th generation Toyota Corolla (E210), which is called traction-s performance low down spring. The product is made of SAE 9254 steel with a solid sky blue coating to protect against corrosion. And in the design and production process, it has been specially optimized, so that it will not produce abnormal sounds such as metal friction sound when compressed to the limit. After loading, the height of the front of the car is reduced by 30mm, and the rear of the car is reduced by 25mm, which is quite obvious.
Eibach Ai**
For domestic car fans, the name Eibach is known through their automotive spring products, but for European car fans, they know very well that automotive springs are just one of Eibach's product lines, and Zhengye is a special spring for industrial equipment, after all, as early as 72 years ago, that is, in 1951, Eibach started by producing industrial springs. Eibach has launched two sets of products for the 12th generation of Corolla, namely the Pro-Kit black spring and the Sportline red spring. The Pro-Kit, an entry-level short spring, offers the 12th generation Corolla a 27mm lower front end and 22mm lower rear end. As for the Sportline red spring, it can reduce the body height more than the black spring, which is 45mm in the front and 45mm in the rear, which is aimed at users who are more interested in vehicle handling. On the springs of Eibach, we can also see the appearance of rubber sleeves, which are mainly used to mute and reduce friction for the springs.
Figure: As a consideration for the convenience of daily car use, we recommend choosing the Pro Kit series, the body height is not the more the better, and it is more appropriate for family cars to maintain a certain approach angle and departure angle.
Figure: It should be noted that excessive reduction in body height will lead to large changes in the suspension parameters of the vehicle, so after replacing the red spring, you need to do an additional four-wheel alignment to ensure that the suspension parameters are in a normal state, otherwise the driving stability and handling of the vehicle will be even worse than the original.
rs-r
RS-R, a well-known Japanese manufacturer of suspension suspension and body reinforcement parts, has provided four available short springs for the twelfth generation of Toyota, namely TI2000 DOWN, RS-R DOWN, TI2000 Super DOWN, and RS-R Super DOWN. The Ti2000 Down and RS-R Down reduce the height of the body by 25-30mm in the front and 20-25mm in the rear, while the Ti2000 Super Down and RS-R Super Down reduce the height by 40-45mm in the front and 35-40mm in the rear. You can choose according to your own needs.
Picture: RS-R Down short spring, because of the space problem, the rest of the products are not pictured one by one.

tein
Tein (Tianyu), a professional automobile shock absorber and spring manufacturer brand from Japan, believes that the majority of fans should not be unfamiliar with it, after all, the TEIN brand itself has a good reputation, and often appears in various exhibitions and motorsport at home and abroad, so that it has a very high degree in China. Tein has launched a suitable short spring product for the 12th generation Corolla, which is part of Tein's S Tech short spring series. After loading, the vehicle height can be lowered by 30mm front and rear. The spring comes with a rubber sleeve for silence and friction reduction.
H&R, from Germany, is a well-known manufacturer of automotive short springs and suspension components. It is also available for the 12th generation Corolla (E210), a set of short springs that can reduce the vehicle's vehicle height by 35mm in the front and rear and improve the vehicle's driving stability.
megan racing
MEGAN Racing, a comprehensive automotive aftermarket upgrade brand from the United States, has launched a short spring product for the 12th generation Toyota Corolla (E210). The springs are made of SAE 9254 steel with an orange paint finish to prevent rust. After loading, the front of the car is lowered by 28 mm, and the rear of the car is lowered by 24 mm.
As a perennial engaged in the modification industry of the first worker, test pieces have become a part of the life of the people, if there are car friends asked and related choices, we will generally recommend the replacement of short springs, first, cheap, even with the material with work, a set down is 3000 below, no matter what car is not a big expense. Second, the support is sufficient, and the cooperation with the original shock absorber will not be too abrupt, especially those big brands, which will be finalized after a long time of testing, so you can rest assured. Third, the so-called "shortening the life of the shock absorber" is pure nonsense. Fourth, I have also used sports springs on different cars for many years, especially for some models that cannot be found casually with sports package suspension, sports springs are the best choice. Fifth, rest assured, there is nothing to follow, and doing four-wheel alignment twice in three years has become a habitual maintenance subject, and there is no need to adjust. Of course, whether it is the original shock absorber, upgraded springs, or even sports suits, twisted tooth suspensions, etc., you must develop good pit avoidance habits and remember to slow down before passing speed bumps, so the shock absorbers are durable.
