The only thing i would say is to the best of my knowledge ALL RST master cylinders are ABS ones, so only have 2 outlets?

As for the piping, its diagonally split from the factory. Inside the MS there is basically 2 seperates cylinders. If you want it as per factory connect the front left and rear right to one cylinder, and front right and rear left to the other!

Doing them diagonally split wont affect how they operate, its just done like this from the factory as its considered better if a pipe should develop a leak.
