12 Ft is A LOT of distance, me braking 12ft later on each corner can do some SERIOUS damage on the track.... And yes I know blah blah blah blah, now you guys don't go talking about a tangent about the distance one would save on the track.

No brackets
OEM 350z, G35 5th & 4th gen Maximas* have the same knuckles. The Z Brembo and base calipers are interchangeable, just different size rotors.
(*4th gen mounting holes are smaller)

I was waiting to update that thread till I was done with the G35 calipers but here goes:
The calipers are not a direct bolt-on if mated with a 12.6" rotor. The holes line up just fine on the 5th gen knuckle, no problem there, but there is just a little bit of scraping from the rotor to the inside of the caliper. Just like the 6th gen caliper setup, you either have to mill the 12.6" rotor down or you can do what I'm in the process of doing and mill down the surface area of the caliper itself. They're iron so milling down 3mm from the caliper shouldn't be an issue.
The G35 dual-piston calipers are definitely an upgrade over the 6th gen setup anyway...just not as direct of a bolt-on than we hoped.

And you're using a 2006 G35 dual piston caliper...? 
Oh...just curious but you drilled your holes only to be bigger, right? Not offset? You are using stock 4th gen torque member? (terminology?)

Yes, I mean they may have been off by a mm because it was hand drilled while the spindle was on the car, but it should be dead on stock.
Not one single mm.

For comparison's sake...and this is by no means an exact measurement. I measured from the inside 'ceiling' to the torque bracket mounting holes of the G35 caliper and a very-stock-fitting-to-12.6"-rotor-caliper.
The difference is evident. It's fine though, I have the tool now to grind down the inside ceiling of the G35 caliper so all is well on that aspect...pics are for educational purpose only.

Glad I read this before ordering a set of 05 Z calipers. Odd how OP's worked and others haven't...also read in 6gen forum bout it not working. I'd imagine this is due to the modified knuckle...may have given the mm or so needed to bolt right up without shaving anything.
Anyone else have success without modifying the caliper or knuckle in any way? Also does this shaving of the caliper or milling of the rotor affect performance in any way? This would be boss if it could work for sure, but for practicality/cost it may be easier to just stick to 6gen rotor/caliper set up (for 5.5gen's that is).

The main difference between 6th gen caliper and the '06 G35/350z caliper is the latter has dual piston. The 6th gens are plug and play, thanks for correcting me jviv.
Take it for what it's worth...pricing will be close to the same for the 6th gen or '06 G/Z calipers and minor modification to the G/Z is needed which isn't a horrible solution.
As far as the performance...I doubt there is going to be much structural damage. The G calipers I have are heavy iron and pretty thick regardless of the 3mm I've milled out.

Regardless you have to mill down a 6th gen rotor about 3mm to make it work...the only difference between 6th gen caliper and the '06 G35/350z caliper is the latter has dual piston.
Take it for what it's worth...pricing will be close to the same for the 6th gen or '06 G/Z calipers and modification still needs to be done to either. Depends on your flavor of pistons.

. From what I've researched it's plug and play with 6th gen caliper/rotor/pads and 5.5gen knuckle. Gonna do some more noob research just to confirm I guess. Don't have the means or time to be milling/shaving/drilling anything. Back to the drawing board otherwise...unless you'd mill the calipers for me and we work it out cost wise

^^Figured as much. So how much work is it to mill out the 3mm from the caliper? Can this be done easily or does it have to be done on some special machine? Has anyone else bit the bullet and tried this with success on their 5th/5.5 gen?

Waiting with baited breath...but I must say the odds are somewhat stacked against you otherwise. Spoke to Brian at fastbrakes about this and he was quite skeptical. Without hesitation he spoke of the difference in radi between the A34 and Z caliper brackets (measured earlier on by MrEous). Make me a believer!

Jeff is right!! There is a difference of around 3mm.
On my initial testing I thought it was the pads making the noise, but no, it was the bracket.
So...... I have an idea.... 6th gen Brackets maybe? Possibly? no idea, but I'll have 6th gen brakes to play with tomorrow night to continue this, the only clearances I checked was the first opening for the rotor, I didn't investigate further.
Edit: Ok getting just a bracket for a 6th gen is quite hard, would require someone to get a caliper with it too, I will still find out though, at least possible news for those who already may have 6th gen brakes.
Looks like this is another mod that requires grinding

I started grinding down on one of the calipers and it almost clears my 12.58" rotors. I ended up going with a different BBK for now but haven't decided on just finishing up the grinding or bailing with what I've already done and set up a FS.
