you may well need the larger bore z32 300zx BMC to match the larger fluid volume
of the 300zx calipers and get rid of the long pedal travel
the stock smaller bore BMC can only deliver so much fluid,so has to over stroke to
get the pedal firm and working the pads onto the disc's
there are three z32 BMC bore sizes 7/8th,1",and 1 1/16th
(and not sure what you can got on the USA spec cars)
I went with the 1 1/16th version to match my 8 pot K sports and z32 rears
you may be better with the slightly smaller bore sizes as can over do it
and end up with a sharp and hard to modulate pedal (easy to lock up)
the K sports are for my 13 but tried them on my 14a as a test
with stock rears+ stock BMC
and pedal needed a rapid second dab to keep it from sinking away
the UK 14a has 4 pots and a bigger bore BMC than a 13 on single piston/sliders
but not enough for the extra fluid volume of 8 pots
just stuff I found when searching on what others have done
