I have 4 piston calipers on all corners and am trying to increase the rear brake pressure to spool a little better on the brake. Currently have stock 1972 master cylinder and proportional valve....What brand and kind of master cylinder do you recommend.
Thanks

Have you tried an adjustable proportioning valve?

As for the M/C, I would recommend contacting the manufacturer of the calipers and see what they recommend for bore diameter and then shop around.

Do you have 2 calipers per wheel in the back?

No just single four piston calipers..Wildwood

Put a dual 4piston cliper kit on it. You need alot of brake in the back to foot brake a turbo car.
