That is not the reason im looking for the 13" rear brake. I bought the 370z track edition brake set up and I think 14" is just to big. Im still having the brackets made for 14" but im also have a bracket made for a 13" front and rear.
I already have a rotor I would like to use for the front that is a 13" and 2 piece, Just looking for something that will work with the factory ebake.
For my dry sump it will be in the location of my power steering pump and I will have a electric PS from some Nissan vehicle. I will post more on it when its close to being done.
