This kit was on my g37xs. The calipers were removed from 370z sport package. Front rotors have approx 10k on them rear rotors have approx 5k on them. The pads have same miles on them so plenty of life left on rotors and pads. The brakes work awesome and have never been tracked before. This is what you get 4 calipers 2pc front and 2pc rear 4 stainless steel braided z1 brake lines (front have some rubbing on exterior of the lines) 4 stoptech sport rotors 2pc front and 2pc rear 4 carbon fiber powerstop extreme pads 1 brand new spare wheel/tire if you’re doing retrofit from base brakes the original spare will not clear the rotors Let me know if you have any questions. Only selling because I’m returning car back to stock.
