if you have good front tires, you won’t lock up as easily.
without the master cylinder, and doing the brake upgrade, the pedal will feel
very spongy.
my rears are stock, with $20 pads and no name rotors.
front are stock z32 rotors and pads.
unless you compare side by side 1 car with z32 brakes all around, and 1 car with only z32 in fronts, you not going to notice the difference.
technically, sure it will throw off the balance, but your not going to feel it unless comparing it to something.
z32 fronts you should be looking at $300-400 with everything you need to swap over, including hardlines.
and you need to cut off or bend back the shield behind the rotor
