2) I would advise against a proportioning valve and tune balance via brake pads. I ran DTC 60/70s front and DTC 30/Hawk blue rear depending on bite or tire compound.

3) With Wilwood 1.75 F (4 piston) and 300ZX rears, the bias was very very close to stock. Your rear 300ZX brakes will NOT move the bias so far to the rear to necessitate a proportioning valve.

Do the math if you would like to confirm for yourself

Goodluck!
That's great input Ralliart! My plan has always been to do the brakes step by step and test after each piece has been complete.

How do you calculate bias? TCE Performance has a calculator, but, I don't know how to get a pad's Cf value.
