rear disks for '71, ZX front caliper ?s

[Dan Baldwin]

Hi there. I'm about to put disks at the

back of my '71 3.1 liter Z. Currently

thinking of the '82-'83 ZX rotors and

calipers and Maxima or fabbed brackets.

Wondering what this'll do to my front rear

bias if I also use a ZX master cylinder.

Anybody know how the ZX front brakes compare

to the early Z's, as far as piston area and

caliper working radius from axle centerline

are concerned?

 

BTW, the car is primarily used for driver's

schools and time trial events with COMSCC

(NHIS, Watkins Glen, Mosport, Lime Rock, etc.)

 

Any thoughts, opinions, advice, other

options, etc. are welcomed!

use a larger ZX master and you should be ok.. you may need a prop valve $50.

but you can also vary the rear pad compound to alleviate rear lockup. use hawk blue for track days and black for street use. definitely not stock ZX pads as you will likely get lockup then

Thanks for the reply, Mike.

 

Bias would be too rearward using the ZX

rear brakes and Z front brakes and ZX

master, huh?

Does the ZX have bigger front caliper pistons

and/or bigger rotors? Trying to get a handle

on how out of balance this setup would be.

its personal preference. if you dont plant the pedal hard youwont have a problem. some like the rears to lock first some like the fronts to.

if you hit the pedal hard the rear calipers are much more efficient than the fronts and will usually lock up sooner.
