My car is at the body shop so I can't verify anything right now. The brake braket on the z31 rear that the calipers bolt to looked different , I took off the z31 calipers with the braket and it didn't bolt up . The only way I see it could work is with the whole trailing arm.I see the maxima braket used on 240z ,to use 85 maxima rotors and 280zx front calipers. Will this work on 280zx rear trailing arm suspension? I want to keep 4 lug , I have moroso studs , just easier. Just looking for a close as possiable bolt on.
