While quieting motion at high speeds, it compels your vehicle to respond obediently to your every whim with no sense of incongruity, even during corrections. This makes possible high-speed cruising with a sense of stability, through moderate reduction in vehicle motion, without uneven road surface disturbance. Sportivo's comfort zone has not been about endowing your drive with a cushiony, airy feel. Rather, it is about excellent convergence, and that it is best to reduce vehicle motion a little to provide a comfortable, non-fatiguing ride, even for those long drives. Reflecting this thinking, this suspension system is designed to reduce bouncing and pitching along with larger vehicle movements, to minimize driver jiggling and produce the sensation of an even, smooth ride. This suspension set reduces the height of the car by roughly 30 to 35 mm, which lowers its center of gravity for improved drivability while achieving sportier look
