Product character	Connecting the strut towers at the top of the suspension and the left and right sides of the floor, A basic item to suppress body distortion.	By connecting the left and right lower arm mounting points, Suppresses deformation of the lower suspension pivot (fulcrum).	Connecting the left and right directions of the indoor floor, It suppresses distortion in the central part of the body that cannot be corrected by strut tower bars, etc.	The open-structure body around the front and rear strut towers A full-fledged design that reinforces the structure three-dimensionally using surface configurations rather than lines.	The entire underfloor, centered around the suspension pivot A full-fledged specification that reinforces the structure with surfaces rather than lines.	The front and rear ends of the body are equipped with ultra-high damping friction dampers. It suppresses twisting and reduces micro-vibrations from the road surface.
Change in riding taste (Commitment)	The suspension movement becomes clearer when steering. Cornering becomes more stable. Vibrations from the road surface are more easily transmitted to the steering wheel.	The feeling of solidity when steering has improved. It becomes easier to feel the movement of the suspension. Vibrations from the road surface are more easily transmitted to the steering wheel.	When steering, the entire body follows firmly. Cornering is stable. With strut tower bars etc. When installed together, it enhances the sense of unity with the car.	You can experience a solid, rigid feel, as if you had installed a roll bar. Not only does it improve cornering, but it also enhances straight-line stability and the feel of driving on uneven roads, resulting in a more substantial and solid ride.	The ride quality has become firmer and more stable, as if the floorboards had been thickened. Positive effects on straight-line stability and the feeling of body roll, You can clearly feel the sensation of the tires gripping the ground.	Whether cornering, high-speed driving, or city driving, It provides a feel that firmly grips the road surface while suppressing any harshness. A refined ride that feels like you've moved up a class of vehicle.
Technical features (Notice)	Prioritizing high rigidity, steel material was adopted. Based on a welded one-piece structure, a high level of rigidity is ensured. It is attached by fastening it together with the strut tower, etc.	The structure is similar to that of a strut tower bar. It is installed using the high-strength lower arm mounting points, etc. Practical considerations were also taken into account, such as enabling the installation of mass-produced under panels.	The center section, which spans the floor tunnel, was welded as a single unit. The one-piece construction ensures strength. It is fastened together with the front seat mounting points. It can be used in conjunction with the genuine floor mats.	Two-directional stress distribution structure, surface pressure distribution structure, etc. for mounting points A specially designed layout that prevents stress concentration. It's a serious, high-performance product, yet it's based on a bolt-on design.	The basic concept is similar to the Tower Brace Set. Despite its sophisticated design with a truss-like frame spread across the entire floor, The minimum ground clearance will also only decrease by a maximum of about 15mm.	The robust disc springs inside the damper ensure excellent body rigidity. From the stroke range at the moment the body is about to vibrate Vibrations are dampened by the elastic force and frictional force of the friction plate.
