A linear type front spring jointly developed with AXON for BD9.
The kit's standard spring requires a high level of stability and mild steering characteristics, and a progressive type in which the winding pitch changes from the middle is adopted, but this equal pitch linear spring has more aggressive stearin characteristics. It is designed with an emphasis on improving steering response and cornering. There is also a balance with the setting balance before and after, but it is possible to have an aggressive run that suppresses the understeer and aggressively attacks the inn.
In addition, since the overall length is shorter by 1.5 mm than the conventional linear spring, no shock-end processing is required when lowering the vehicle height. Depending on the type of tire, it may be difficult to lower the vehicle height due to its thickness, so depending on the situation, it can be used not only for the front but also for the rear.
