Still seasoning/braking in but first impressions are awesome. The braking is MUCH more firm and definitely more consistent. You get a lot more feedback through these brakes. These things are so big that I had to move my inner wheel weights a little further forward so it wouldnt rub the caliper!
Ive been to Baer's facility to do a shop tour video with them and Carroll Shelby and its definitely a first class place. Their brake are forgings are from Wiesco and are made from the same metal they make their pistons from. You can check out the shop tour I did here

Full installation/test video coming soon on this install.

Having 6pot all the way around.. won't that effect the Braking bias, and make the car rear unstable at high speed braking?

Not at all. Your car through line length, diameter, and internal bias from the factory controls the cars bias. Having 6 piston rear brakes doesnt change the bias as it still has the same fluid pressure going into them. What it does is allow for a much more controllable and consistent braking feel.
Think of the force of a single stock or even 2 piston brembo rear brake works. You have 1 or 2 pistons pushing the pad from the center. So in essence the pad it gripping more in the center of the pad then the outside which can create uneven heating of the pad. Also the larger the brake piston, the higher risk of osculation/deflection of the brake piston can happen. By having 6 piston rears you first off have pistons on both sides of the rotor now instead of 1 side, but with that you have 3 smaller pistons on each side the rotor that applies the same brake pressure, but now evenly across the pad and not just to the middle. So between the equal pressure and more pad volume it will give you more consistent and better braking, but enough to effect the bias of the car? Not at all.

Actually, one would have to calculate the total piston area of those 6 pistons vs oem. Also one has to take into account the larger rear rotor size as that increases the brake torque figure.
One can upgrate the front and rear brakes if the bias stays the same. But it looks like you are put same setup in the rear as in the front. That WILL negatively affect the frt/rear bias ratios by moving the bias too much to the rear
From Stop Tech's site:
we will bring forward again the lists of modifications which can influence front-to-rear bias.
Factors that will increase front bias
Increased front rotor diameter
Increased front brake pad coefficient of friction
Increased front caliper piston diameter(s)
Decreased rear rotor diameter
Decreased rear brake pad coefficient of friction
Decreased rear caliper piston diameter(s)
Lower center of gravity (i.e. lowered vehicle)
More weight on rear axle (i.e. loaded)
Less weight on front axle
Less sticky tires (lower deceleration limit)
Factors that will increase rear bias
Increased rear rotor diameter
Increased rear brake pad coefficient of friction
Increased rear caliper piston diameter(s)
Decreased front rotor diameter
Decreased front brake pad coefficient of friction
Decreased front caliper piston diameter(s)
Higher center of gravity (i.e. raised vehicle)
Less weight on rear axle (i.e. unloaded)
More weight on front axle
More sticky tires (higher deceleration limit)

I'm by no means an expert on the subject, but I have heard that the Z needs a little more rear bias when on the track. While this setup may not reproduce the stock brake bias, perhaps it does effectively change the bias to one that is more ideal for on the track.
Currently, I use the stock brakes on the track and man are they bad. I'm starting to look for a big brake kit and find the Baer system intriguing. I want to learn more about this system.
One definite positive about this system is that it uses stainless steel pistons, which isolates the brake fluid from the heat better than aluminum. Not sure what StopTech uses, I can't find the material noted on their website.
