Waste of time and money, say lifetime warranty not at all. Company fights to say their product is perfect, when its garbage. Air ride fail to stay up and rear struts internal parts constantly banging.

Best calipers, best customer service. Installed 8 pot front brake kit and 4 pot rears on my e46 M3, they preform like a dream, better than wellwoods on my rx7 and way better than brembos on my porsche, wish I have D2s for every car I drive.
