BMC BM-50 1" or BM-57 1 1/16"?

Hi everyone, I've been a member for a while however this is my first post lol

Its been 9 years since I've used my S14, when I bought it I didn't know about cars.
Anyhow after 9 years of my car sitting in the garage my BMC is no good, the car currently has a BM57 - 1 1/16".
I have Brembo front calipers from a G35 and Im switching out the rear to STI Brembo calipers.

Is there much difference between the 1" bmc and the 1 1/16, I mean its only .0625 thats almost nothing, the price on the 1" unit is way more attractive. I can get a nissan oem one for $70.
I remember reading the larger one requires more pedal effort and I do recall not liking the pedal effort on mine, maybe ill be better of with the 1" unit.

I also know I can change the Booster to the 300zx to help with this too. but 1" vs 1.0625" is it really worth double the price.
Can anyone chime in with their experience between both.

Currently taking apart the rear brakes for the Brembo upgrade

Yes, 1.0625 x the length of the master cylinder = much more fluid than the 1”. I’ve owned all the master cylinder combos and can say without a doubt that the 17/16’s one is the way to go, spend the extra $30 and get the right one.

Alright guys for the sake of having all the info can anyone tell me what the length of the BM-50 1" bmc is? My old non working BM-57 is about 5 7/8".
