Product character	A basic item that connects the strut tower at the top of the suspension and the left and right sides of the floor to suppress distortion of the body.	By connecting the left and right lower arm mounting parts, deformation of the lower suspension pivot (fulcrum) is suppressed.	By connecting the left and right directions of the interior floor, distortion of the central part of the body that cannot be compensated by strut tower bars etc. is suppressed.	Full-scale specifications that three-dimensionally strengthen the front and rear strut tower peripherals of the open structure with a surface configuration instead of lines.	Full-scale specifications that strengthen the entire underfloor with a surface configuration instead of lines, centering on the suspension pivot.	Equipped with ultra-high damping friction dampers at the front and rear ends of the body.Suppresses twisting and suppresses slight vibration from the road surface.
Change in riding taste (Commitment)	Suspension movement becomes clear during steering operation, and cornering is stable.Vibration from the road surface is more likely to be transmitted to the steering.	The feeling of firmness during steering is enhanced, and the movement of the suspension becomes easier to feel.Vibration from the road surface is more likely to be transmitted to the steering.	Steering When steering, the entire body follows firmly and cornering is stable.Improves the sense of unity with the car by installing it together with the strut tower bar.	You can enjoy a solid feeling of rigidity as if you assembled a roll bar.Not only when cornering, but also the stability of straight running and the feeling of running on uneven roads change drastically.	For a stable and hard ride like increasing the floor thickness.You can clearly feel the positive effect on straight-line stability, the feeling of rolling, and the feeling of the tire kicking the ground.	Regardless of cornering, high-speed driving, or city riding, the feeling of ruggedness is suppressed while firmly grasping the road surface conditions.A high-quality ride that feels like a higher-grade vehicle.
Technical features (Notice)	Steel material is used to prioritize high rigidity.A high level of rigidity is ensured based on a one-piece welded structure.Tighten and attach to the strut tower.	The structure is the same as the strut tower bar.Mounted using a high-strength lower arm mounting part.Consideration was also given to practical use, such as enabling the installation of mass-produced under panels.	Strength is ensured with a one-piece structure in which the center part that straddles the floor tunnel is integrally welded.Tighten together with the front seat mounting part.Can be used with genuine floor mats.	Dedicated layout such as 2-way stress distribution structure and surface pressure distribution structure where stress is not concentrated at the mount point.Although it is an authentic school, it is based on bolt-on design.	A basic concept based on the tower brace set.Although it is a full-scale design with a truss-shaped frame stretched over the entire floor, the minimum ground clearance is only about -15mm lower.	The tough disc spring inside the damper ensures the rigidity of the body.Vibration is suppressed by the elastic force and frictional force of the friction plate from the stroke range at the moment when the body is about to vibrate.
