It rides fine once you take off the run flats. Also helps with torque steer (eliminates it) and cures the tracking issues on the freeway. S or better, without question. In 2011 they gained about 200 lbs. Just, maintain it and maybe get an oil catch can. Only issues I've had were trim on the hood from tracking it, and stuff, and the hatch button broke so I rigged it. But, they usually replace those under warranty. Plenty of not terribly expensive mods.
