My Z has the MM rear disc brake conversion using 240zx calipers and 300z non ventilated rotors.
I have all the elements to install ventilated front discs and Toyota truck calipers. I do not have a functioning proportioning valve as I gutted the original.
After reading all the posts describing this swap to be inherently unbalanced in that the Toyo calipers are too large in comparison with the 240zx rears, I'm thinking seriously about returning the front to stock specifications: stock rotors and calipers, and keeping the MM rear discs [hey, they look good and the drums have long since disappeared].
I think I should install another after market proportioning valve in my rear brake line. But I don't know if it is "necessary" or not from a safety standpoint. This is not a track car; but, I do wish to have predictable behavior for panic stops from a straight line.
Does anyone have any experience with stock brakes using only the MM rear brake set up?
I tend to ascribe to both "more is better" and "while I'm at it I might as well ........ ." views of life.
This time I really want to do it right.
Please comment.
