The opportunity to commercialize Pillow Upper was an event at the Super Battle held at Tsukuba 2000. I set the front camber to -5.8° and went on an attack, but when I set down after the run, it was obvious that the outside of the left front tire was worn out. That's right, the situation where the tires "hit the outside" is severe. At this camber angle, it was almost unthinkable for me to hit the outside so far, and I came to the conclusion that something was moving somewhere that shouldn't be moving. Further verification revealed that the culprit was the genuine upper mount. In short, when a large cornering force (lateral G) is generated, the genuine upper mount, which is a rubber bush, deforms and the damper attachment point moves outward. When this area moves outward, the camber decreases, causing the tire to hit the outside, making it impossible to secure an effective contact patch, which led to increased understeer. Of course, this symptom will only get worse as the larger the cornering force is generated, the more the camber will decrease. TM-SQUARE pillow upper mount is a genuine upper mount made of rubber bush, turned into an aluminum block that does not deform, and a pillow pole is attached inside. By not moving the upper mount, the damper mounting point can be prevented from moving due to cornering forces, and the symptoms of camber reduction during driving can be greatly suppressed. As a result, during cornering, the tire's contact surface is secured, "outside hitting" is prevented, and understeer is also reduced. Of course, since the camber does not change while driving, it is also possible to set the initial camber value to a smaller value. Also, the genuine upper mount, which is a rubber bush, has a negative effect on the damper stroke. For example, the suspension strokes due to riding over a gap or shifting load, but if the rubber bushing of the genuine upper mount deforms before the damper moves, the suspension as a whole will stroke, but What happens is that the damper is not moving. Then, once the rubber bushing has finished deforming, the damper/spring suddenly begins to stroke, but the ``sudden hardness'' that occurs at this time not only makes it difficult to get good tire grip, but also affects ride comfort. , it also greatly affects the ride quality. TM-SQUARE pillow upper mount does not return camber due to cornering force. Also, the spring/damper should move smoothly from the initial stage of the stroke. These two benefits create a linear, direct, and responsive steering feel. On the other hand, the disadvantage is that it cannot absorb the noise generated by the running tires and the vertical movement of the suspension. With the genuine upper mount, there is a rubber bush between the suspension and the body, which absorbs most of these noises, but the TM-SQUARE pillow upper mount is made of aluminum block, so these noises are absorbed by the genuine upper mount. It cannot be absorbed like an upper.
