Also keep in mind the rear brakes need to be changed as well. The 05/06 has larger rotors out back too.
Calipers are the same, but the pad support bracket is different. If there was a source for this bracket only, you could just swap those and the rotors and dust shield (or trim it since the drums will have to come off to swap) and have the larger 11.1 rotors to fill up your wheels better.

The stock 2004 G35X 17 inch 6-spoke do not fit up front at all even with spacers. Rears fit with a mild spacer. I've upgraded to 2005-06 18 inch 10-spoke sport wheels for my winter setup - the ones that look like the 19 inch coupe Rays. These fit at all four corners with 15mm spacers. Summer tires are on 19 inch aftermarket wheels and fit directly.
My guess is the 2006 G35X 17 inch 7-spoke will have the same problems as teh 2004X - rear would fit with spacers, fronts won't at all. The 18 inch 7-spoke versions have a better chance of fitting with spacers at all four corners. Just speculating though.

I really want a wheel that I don't need spacers with to clear the calipers.

Can't speak to the 7-spokes directly. But, I have coupe Brembo's on my 04X with some knowledge.

The 18" 7spoke coupe rims will clear brembos since that's what the g35 coupe w/brembo's came with.
18" 7spoke coupe rims or 18" 350z Track rays would work. Coupe rims would look just like your stock rims on your 06X.

Just thought of something.
What size pistons are in the single piston 03/04 caliper vs the 04/05 dual piston caliper?
If the surface area of the two calipers is very different, it will change the feel of the brakes if the master cylinder isn't properly sized to the fluid volume requirements.
In other words, if you put calipers on that have a smaller surface area of the pistons, the pedal gets firmer slightly. If you put calipers with a larger piston surface area, the pedal gets softer.
It's something i've never seen addressed with any of the brake swaps. Nobody ever changes the master cylinder.
However, i'm quite familiar with brake retrofits on Mustangs, and changing the master cylinder is common in order to get pedal feel "just right".
Does anyone know the piston sizes of both calipers?

The 05-06 18's, you used 15mm spacers cause that's what you had or you NEEDED 15mm spacers? I have these rims as stock for my winter setup. I have 10mm spacers so you got me kinda worried. Any input you can provide would be greatly appreciated (putting on my brembo's this month)
And to be clear, my 18 inch winter wheels came from an 05 sport sedan. If using coupe wheels pay attention to offset differences (resolved with spacers!).

Rears will fit without spacers. 5mm spacers will not fit up front. The front will be close with 10mm, not sure exactly if it will fit. I chose 15mm because these were the smallest spacers I could find with built in studs. All others use the original studs, which concerned me on length. I might have needed to replace with the studs with longer versions. I opted for Ichaba V2 15mm spacers

Cost maybe? The x model was the most expensive model in the sedan line-up, so maybe sticking with the old cast iron brakes saved them a few bucks and help them meet a target msrp? Who knows.
But just kinda odd the new brakes debuted on all the 2005 model g35s sedan and coupe except for the awd model. Odd.

Edit: were you referring to Brembo or 05/06 OEM calipers?
