Product character	Utilize mass production dampers.By replacing only the spring, the styling is improved and the sportiness and ride quality are balanced.The view from the driver's seat, which is moderately lowered, is also fresh.	Damper (shock absorber) with the same shape as mass production.An adult tuning model that is oriented toward riding taste and enhances handling performance while maintaining the appearance (vehicle height).	Vehicle height adjustment type that combines a specially designed damper and spring.The upper mount utilizes mass-produced products. The best street model that AutoExe thinks.	Vehicle height adjustment type that combines a specially designed damper and spring.High roll rigidity model for high load driving on circuits and windings.	Even if you replace the spring or damper, if you are worried about the roll, it is a suspension adjuster that moderately suppresses the amount of roll.There is no change in vehicle height.	More than mass production, less than tuning.An out-of-print sports car exclusive product with mass-produced dampers, springs and genuine upper mounts.
Change in riding taste (Commitment)	Natural handling with less abrupt feeling that keeps the ride quality of mass-produced cars. Since the vehicle height is assumed to be for two people, the ride quality will deteriorate when a large number of people are on board.	A high-quality ride that suppresses the feeling of rolling and enhances the sense of stability.With the same stroke as mass-produced products, there is no failure in riding comfort even when riding a large number of people.	A ride with a clear outline that the car reacts unambiguously according to the driver's intention.The total sportiness is high, but the comfort of the passenger and rear seats is also ensured.	Sharp agility with little play that reacts instantly to steering operation.Creates a solid driving sensation with a high sense of change regardless of the speed range in retreating the ride quality and trading.	It reduces the amount of roll of the car when cornering and reduces the driver's anxiety.The effect on the ride quality is small, but the reaction force from the steering increases slightly on uneven road surfaces.	It adds modern-style accurate and uneasy handling and a flat ride feeling without impairing the ride quality of the new car.To natural handling without patience peculiar to out-of-print cars.
Technical features (Notice)	The vehicle height is basically -20mm considering the connection between the stroke of the mass-produced damper and the bump rubber.The spring constant is limited to the minimum increase that compensates for the stroke reduction due to the vehicle height reduction.	A high-precision micro-low speed valve that quickly raises the damping force from the very low speed range is used for the piston.The emphasis is not on simply increasing the damping force, but on proper control of the roll speed.	A high-precision damping force fixed twin tube damper that is advantageous for the rise of damping force from a very low speed range and a spring designed based on a spring constant of 110%.The recommended vehicle height was kept at -15mm.	A monotube damper with excellent heat conversion capability under high load.Assembly design that combines a series-wound spring with a spring constant of 200% or more and a reinforced rubber upper mount.	Set the spring constant to about 110-200%.Specifications that avoid excessive diameter increase that causes unstable behavior such as sudden oversteer and understeer.	A high-precision damping force fixed twin tube damper that is advantageous for the rise of damping force from a very low speed range and a spring designed based on a spring constant of 110%.Assembly design including bump rubber.
