Hi guys new to the forum here. I got a 75 280z which im putting an Rb25det in. I wanna finish the brake set up prior to installing the engine and transmission in. For the front i have the toyota 4 caliper set up and in the rear modern motorsports 240sx set up. Ill be buying the Wilwood 1” master cylinder and getting a reman brake booster from autozone. My question is this. Do i need the proportion valve? And also what exactly is it that i have to delete on the fuel line set up. Btw ill be running new lines. Any input on what im missing is good. Ty
