I have been working on a bracket set to use 350Z brembo calipers. Its pretty common knowledge that the fronts bolt up by drilling out the mounting holes. The rears require a bracket to work. These are designed to use a readily available (much larger) 370Z rotor. The brackets are machined from 6061-T6 aluminum and bolt on to the rear knuckle without modification.
This is what i've come up with so far. we just moved cities so once im set up here ill give an update with how they fit.
