NISMO Stabilizer Kit For Fairlady Z Z33 VQ35DE VQ35HR 54600-RSZ30Brand NISMO Series Name Stabilizer Kit Product Descriptions This stabilizer improves cornering performance by joining the left and right side suspension with a highly rigid bar. When cornering, differences in suspension stroke cause the bar to flex and exert a counterforce that pushes the tires to the ground while cutting roll. When going straight, none of these forces are called into play, so the bar remains inactive and the car's ride unaffected.
