I have zero issues with pad noise running MX72 Plus but YMMV. I'm using the stock Brembos so not 100% identical to your Sumitomo setup.

Are the brembos better than the sumitomos?

Well, yeah. They're bigger, for one thing, so they soak up more heat from stops before calling it quits. They are also stiffer calipers. The Sumitomos aren't terrible, but they are definitely not as stiff as the Brembo calipers.

Update guys: Brakes aren't squeeking as bad during normal driving. They only squeek a little bit now after i mash on the brake really hard and then they will start squeeking slightly when coming to a complete stop. Still a mystery on why that is, but thanks everyone for the help.

Sounds like you didn't install the missing brake shims/hardware.

I dont understand how shims will cause that... the squeek is coming back now, but it comes back in really random times. Sometimes when i go on the brakes hard and it gets hot, then it will start to squeel. Sometimes i'll drive normally and it will not make a noise. And sometimes ill drive normally and it will STILL Squeel. This is driving me nuts.

Yeah ok, so have a think about it. What is sound? A vibration that propagates as an acoustic wave? 

When the pad and disc make contact, there is vibration. That vibration causes your lovely high pitched noise. 

The shims prevent the transmission of vibration.

No vibration, no noise. 

Now lets keep thinking about the situation. 

You are an OEM. You are trying to make a profit. Why would you manufacture all of these unnecessary brake shim hardware if it does nothing? Is that money well spent?

Look at all of the stock cars around you. They are dead quiet. They have brake shims/hardware. 

Your skyline came from the factory with quiet brakes. It also came with brake shims/hardware installed.

If you cannot install the brake shims/hardware, clean off all of the built up brake dust. If you still can't install it, get your hands on a workshop manual, instructions, watch youtube videos or just take the car to a mechanic who can do it for you. It's a 5 second job so should be very cheap to do.

Shims are changing the Q factor of the resonant peaks in the brake system. Sometimes you might not have the right conditions to trigger those resonant peaks. If you can't fit the shims in the brake pads you need to push the pistons back into the caliper.

Just remove any shim or pin you like if you don't think it makes a difference. Ignore what Nissan designed. 🙄

Update: I got the rotors turned by a local machine shop. This cured the squealing.

Is the girlfriend still your girlfriend and does she ride in the car now?

It always makes me laugh when I hear things like this, when I was a young bloke I bought a old Mk1 Escort, one of my mates said "how do you expect to have a girlfriend in a old car like this", my reply was "if she doesn't like the car she can walk, and if she is more interested in the car I drive than me she can fark off"

This is how you can tell if you have a good woman, they care not about things like the cars you drive or what it sounds like

Pandering to crazy obsessed women who care more about how they look in a car than the person driving it is something that I've always kept away from

Not saying my Mrs isn't crazy at times, but it's typically me being a idiot that incites the crazy 🤪

Squealing is aids.

Street cars, weekend track cars are not allowed to squeal.

Funny you ask, because its been about a year since i made this post. She is no longer my gf now lol. I have a new one though that didn't mind the squeeling.

You've had some decent suggestions above now, I'm just going to suggest the obvious.

Change girlfriend, problem solved. Other random unpredictable problems may present themselves. Your experience may vary...

Seems I provided sage advice. Glad your problem/s are sorted.
