While they were designed as pretty much a bolt up affair for 240sx's, the Z required a washer on the top bolt and a very small spacer for the bottom no where near 1" I just didn't want to run 4 washers so we machined a spacer. I gave the specs to the fabricator and he will be sending me 3 brackets with these modifications so this kit will be more along the lines of a bolt up affair as well. Unfortunately I don't have any finished pictures of the set up but there are some on Facebook. This kit uses a 12.75" 350z rotor and I have them behind 17" wheels on this vehicle.
