It...Stops...AMAZING...some members here were telling me that I wouldn't really feel the difference between the stock brakes and the Brembos but I have to disagree...there is a TREMENDOUS night and day difference even over a full factory brake job...I can stop from a 45 roll instantly (if I don't mind everything in the back seat to go flying through the car)..
Handling on the new tires, I haven't really put them to the test yet but it feels alittle better than my stock 16's did but not by a HUGE amount, but noticeable.
I came to a hard stop from 30 MPH in our subdivision and threw my mother out the seat and braking feels SO much more confident than it ever has before in this car and it outperforms braking in any of the vehicles we own... ...This upgrade is a MUST do...

However we need to put things in perspective. The amazing stopping power you described sounds like what you get with good pads on the stock system. I can come to a halt from 60mph like its nothing and throw my passenger through the window easily, but certainly couldn't do that with the stock pads or oem replacements. The difference is in the pads.
A "Full factory brake job" sucks *****, the factory pads were ****, oem replacements are ****, autozone replacements are **** and tire shop replacements are ****. You have to actually buy good pads and not rely on shops to throw some ceramic junk on there.

Everything works and brakes perfectly still but I now have a concern.
I am getting VERY loud squeeling from what SOUNDS like the driverside front brake when Im crawling to a stop from 15 MPH or less. Its completely quiet on higher speed stops or hard stops but those slow rolling stops sound like someone relentlessly grinding their nails on a chalk board and its loud.. what is causing this and how can I fix it?

Bedding the pads is a very important step.
Just installed my CTS-V 4 piston brakes with hawk HPS pads and they're dead silent, not to mention how they bite like a ****. I can engage ABS from 60+mph with 315 R888's out front, one of the best mods I've done so far.
I gotta do some 60-0 braking tests, I would bet my car would be up there with some of the modern pony cars

Dang, now I feel like a douche, nearly $1k invested and I forget the most important step. I'm going to try to bed them, I mean..it can't hurt at this point. I'll also put some grease between the pistons and the pads when I get time to take them off.
I need to note though, even on hard stops, my ABS is not triggering at all. I mean it throws everything out the seat when I make hard brakes and I know they're fully optimized as before I did this it stopped worse than my 2013 G37 and my 2015 Camaro and now it makes those cars feel like they have weak brakes.

Meanwhile I went and bedded them - 4 65 MPH to 45 MPH slow downs then 6 65 MPH to 10 MPH hard brakes. It's not squeeling as bad as it used to and it doesnt always do it like it did before but once in awhile it will still squeel..I'm afraid of warping my rotors if I do this too much..
Front rotors after bedding them:
