Perfect balance of sport and comfort Exceptional handling and braking in dry and wet conditions Twist edge chamfering Control the block rigidity by chamfering the edge part of the block into a twisted shape. And even when it is attached to the driver’s seat side, even when it is attached to the passenger’s seat side, it is effective for suppressing uneven wear. Precise groove arrangement The grooves which look like one connection are actually shifted in millimeters. By shifting the timing of grounding, the generated noise is dispersed. It prevents you from concentrating on a specific frequency band and reduces harsh noise. Single edge chamfering By partially applying precise chamfering, we control the occurrence of uneven wear and suppress deterioration of quietness. Staggered arrangement of grooves and sipes Optimize the rigidity of the block by placing non-penetrating grooves and sipes at precise intervals from the left and right. It improves steering stability and improves silent performance.
