Purchased these last year and put less than 800 miles on them. Comes with everything to mount on e46 m3 and get you on the road in style. 380MM rotors front and rear. 6 piston front calipers and 4 piston rear calipers, two piece floating drilled rotors and steel braided brake line. These look exceptional behind any wheels and i constantly get complements on how good they look and pop. Parting out my car back to stock only reason for sale so everything coming off. Stopping power on these are exceptional.
