Even the Brembo system is a 4-piston caliper. The rotors are 332mmx32mm, which, IMO is not worth it for 2,700 dollars. That's also only for the fronts. We need a solid 6-piston front/4-piston rear setup with at least 32mm thickness for a reasonable price.

Q45 guys: Brake Upgrade Packages!
May as well use better pads as well... Most aftermarket pads are around the same price as stock pads.. The 300zx pads work well with the skyline upgrade package.. The metal matrix pads stillen sells seem to be good as well.. We have many choices in this regards.. I guess it would depend on the system we end up going with.. Baer brakes has a place nearby, maybe I'll check them out, and see if they can do anything for us.. If nothing else works out..
AP racing should do something with us... Duaine has an AP racing kit, so hell, all we would have to do is that replicated..
Whatever we do, WE MUST come up with rears as well as fronts...

90Q45blue....your idea sounds great for the 6/4 setup with 32mm thickness. I think that either we find a 6/4 or a 4/2 setup will all the goodies added in. I would probably go for the 6/4 if the price was right as if I am going to do this thing....might as well do it right and I would love to see the look on peoples faces when I can out break them on the freeway at 100mph+.....it would give me much more confidence going 100+ knowing that I could bring this monster to a stop relatively quickely to avoid and accident....
BTW....I really don't like this G35 sedan I got right now. I am sorry G35 sedan guys....but this car is just not me. Besides the funny slap stick shifter that I thought I broke earlier today just testing it out easily...the damn radio volume keeps rising and lowering according to your speed but it overcompensates. What was the engineer thinking when they set this function...He must have been deaf or something as it gets way to loud when I hit 70mph and I have to turn it down. But then when I slow down I can't hear the dang thing. Makes me wonder if I am ever going to like all the new gizmos in some of these car. Just give me a tire burning engine, ac, and a basic stereo that does not have a freaking mind of its own and I will be happy.

Damn!
You guys have been BUSY! I was just planning on putting together a discounted package with some OEM-size drilled or slotted rotors, SS lines, some hi-po pads and fluid and some speedbleeders.
FYI - RE: the Metal Matrix pads - this is the LAST set of them I'll buy. My next pads are gonna be the softest, most dusty things I can find. These are too hard, they fade badly under hard hot braking, and serve only to prematurely wear the rotors - I'd rather change pads every 10K than eat up rotors.
Gonna go with the Hawk pads - They come highly recommended by the F-body guys.
Are the Z32 rotors bigger than our OEM's?

yeah...I am surprised as well at the amount of attention the brakes have received as usually most people are just interested in power power power and forget to balance out the car. I think that is says a lot about us. We want our cars not only to accelerate well, but to also be able to stop good also. I am seriously considering a brake upgrade, but really don't want to spend more that $2,000 for a really nice full blown system that would make a noticeable difference in stopping distances.
Metal matrix sucks? Go figure 
They are cheap, and recommended by stillen..
Hawk makes awesome pads, I didn't know they made em for our cars...
Greg,
Baer brakes has a warehouse at thomas/35th ave.. I used to work right next to them.. Perhaps they would do something for us... They make really high quality brakes, and are local.

Is there a stock rotor that is an upgrade to the Q besides the Skyline? Something that doesn't require a special bracket?
Z32 perhaps?
If we can get a hold of that bracket that was discussed earlier, it shouldn't be hard to replicate... NOTE: I'm not volunteering, too many damn projects on my plate!
My old GS had a Wilwood system that was designed for the Camaro - Old GM stuff is SO interchangeable!

sounds like a good plan...I don't need to pay for the name "brembo" or whoever. I just want them to be reliable & functional for a reasonable price. I can't get over that big name brakes cost $2,700 just for the fronts when I can get so much more for my money...heck I could buy an entire used Q for that price. There must be other no-name 6 & 4 piston brake calipers out there that are just a good as the brembos or close to it for a lot less that will work for us.
Of course, we are talking hardcore brake systems here...
If you can find a way to get thicker rotors on the Q, without much work/expense, I'm sure just about anyone would do that... Espically since Stock Q rotors are pricey.. you could probably make a much better replacement, for the same amount of money

I don't understand how the difference in rotor thickness can be the only determining factor (besides diameter) in whether an upgrade will yield the desired result.
Dumb country boy logic would dictate that if the rotor were a larger diameter you would have more leverage by grasping the rotor farther away from the center of rotation.
Weight, beyond a certain point, seems counter-productive if you can use a forged aluminum center section to help dissipate heat. (floating rotor)
And one thing I haven't read mentioned is the difference in swept area from one system to another. (the size of the pad).
For a simple upgrade reference, the hot ticket on an old B13 Sentra chassis, was the NX2000 rotors/calipers. IIRC, they were only slightly larger diameter, slightly thicker, but the swept area was drastically larger.
Also, if they are forged aluminum calipers, they would also assist in heat dissipation.
Am I missing something, or just ignorant?

No, you are correct, but there is some dissension on heat transfer from an iron disc through an aluminum hat to the hub carrier. Heat transfer from the pistons to the caliper is probably negligible due to the pistons being floating. I would think much more heat is transferred to the brake fluid since there is direct thermal coupling. So alloy calipers are mainly lighter and (hopefully) stiffer in that they have less flex.
Lighter calipers would be an aid to heavier rotors (in mitigating the increase in unsprung mass), which is what a brake that will resist heat defomation needs; increased thermal inertia due to increased mass. However, in a one time stop, increased rotational mass is the enemy.
Hence, swept area is key, given the same pad formulation. A greater swept area will allow finer control and more clamping area to spread the friction and heat on the rotor. Remember the old R&T summary pages on the road test summary page with the swept area/ton?
Finally, if you can lock the brakes or trigger the ABS now, the tires are the limiting factor, and no increse in brake size or diameter is going to shorten that first stop. However, rotor life in specification and many repeated decelerations (pursuit or sport driving) performance will increase with larger, heavier rotors and more pistons in a stiffer, lighter caliper, given the same brake pad formulation and thickness and fluid.
Other issues, such as deeping the hydraulic assist ratio between the front and rear breaks constant are ignored for the moment.
