Just saw a scanned 95 dealership brochure today for the 626. Apparently the 4cyl manual 626 was 2743lbs and the 6cyl manual was 2906lbs, but it doesn't say which trims those are. If all that's different are the motors and rear disks, it's a bigger difference than I thought.

Ripped from PT:
"Every model of Mazda6 front brakes fit our vehicles [PGT], if doing this setup; you must be consistent with the year model you are using. So if you by calipers for a specific model, you must buy the matching rotors and pads. Parts are not interchangeable between models. Here are the specifications of the different models and what wheel diameter is required for them to fit:
Disc diameter:
03-05 Mazda 6 => 11.1" => Fits no problem with a 16" wheel
06-07 Mazda 6 => 11.8" => Fits no problem with a 16" wheel
06-07 MazdaSpeed 6 => 12.6" => Must have a 17" wheel minimum"
With 280whp on tap, I think a few lbs in rotational mass will be almost not noticeable. And if it is, it's a small price to pay for not having the thought of brake fade dangling in the back of your mind while ripping up the track. You'll be at around 3x the power that the P5 came with, and those stock brakes are definitely not up to the task of hauling it down to 60 from 130-140mph on the back straight of Mid-Ohio lap after lap.
I bolded the quote for reference... 17" rims are a minimum, but some may not work because of inner diameter. Please note back to what I said about a MS6 owner with 17" rims and needing to grind a little bit off the caliper to make them fit.
Yes, 17" rims will fit but they will have to be the right ones and a test fit may be needed.
As far as specific models of calipers go.... I do agree if you are talking about the difference between regular Mazda 6 and MS6, however if the RX8 rotors may be an option as .1" is really very minor.
I will let Evan research this fully and come up with his own conclusion and I really am curious because it may open windows for my MS6.
Edit: Also, Evan will have my old MS6 rotors to use for testing.

Shae, anything you want to include with the P5 would be awesome. But I don't want you to feel like you're getting ripped off, ya know? Want to throw in the RSB, Blizzacks and car cover? Of course I'll say yes. haha. But honestly, I've already got a Progress 22mm rear sway I would put in, the car won't see winters so I wouldn't need the Blizzaks but the cover would be aswesome when she's sleeping in the garage. But even if you want to throw all your extras in and I can sell them and send you a good chunk of the money they sold for. It's up to you. 
Chris, PM me a price on the rotors. I looked up new (rebuilt) calipers from RockAuto and they're about $120 each so it's not too bad. Some clown wants $300 for a very used set here on 247. But I would swap both fronts and rear to make sure everything is still balanced on the chassis. I can't really see where upgrading rotor/caliper size would "hurt" any performance, per se. And I can check rotor clearances with my wheels when I have a setup on the P5. After more research is done of course. haha. But it would be nice to have MS6 brakes on the P5 for sure.
And in other news, looks like I'll be ordering a Turbonetics GT-K 350 next week. It should work very well for my application and a lot of the turbo PGT's are running that same trim.

I don't think Fez's MS6 is ever working... 
But good call. And that was just a quick looksie on Rockauto for calipers. I can't see them being more than $150 a piece for new (rebuilt) ones.
I also picked up a used KMR 4 point ladder brace to help with the clearance issues of the downpipe.
Nate- we still have a deal for that GT Spec brace right? Even though I didn't get you your hatch struts...

Just an FYI, our e-brake cable does not work with the rears, and you need to flip the calipers to the opposite sides so the bleeder is in the right location. I think some people made custom brackets for the rear to fit, but I've never seen any pictures of them.
Evan, been meaning to ask you, do you want any of the extras with the car?? The un-installed RB rear sway bar, blizzaks, etc? Since you're having the car shipped I'll be limited in what I can stuff in it...
Shipping companies don't like when cars are loaded up with stuff. I got an earful when I got the Bav because the previous owner loaded the trunk and back seat with stuff. Just a heads up.
I'll look into more when I have the suspension sorted first. But yes please, StopTech slotted. Thanks!
Thanks, mate. I'll look into it more. We talked a little bit about the bleeders. If they're in a wonky position I can put in some speed bleeders so air won't come in. There is a valve in them so they only flow out.
No worries on the stealies then ,Shae. I want the shipping company to take extra good care of her so I wouldn't to risk them being whiny bitches. haha. Thanks, though!

Im doing research first. You have any tips or sites of where I can get a kl motor
Ebay is a good site for KL's. But stay away from Tiger Japan in Texas. There have been a couple guys go to their shop to check it out and it was pretty rough. Apparently an old dude on a forklift backed into a bunch of B18's. doh!
Do you want a curve neck (170crank horde powa) or straight neck KL (200 crank horse powa)?
I got my last motor from Vtec_Motors on eBay and it was really clean, very low miles and is still running like a champ in my Milly. JDM Engine Zone and Depot are two places I've been looking at for my next motor. Zone is in Jersey so they can ship cheaper than from Canada. I've heard good things about them and their motors are pretty cheap.
A tip; When you think you've done enough research and want to start buying parts? Do more research. haha

So just out of curiousity, not trying to be a dick or anything because that's how this is easily going to read...
Didn't you nix the idea of the MS6 brakes after several people (who actually track their cars re: not me) told you that the MSP set up would be more than sufficient for what you are going to need?
There's a good chance that you covered this decision already. I've been so busy trying to keep up with work that forum time is at a minimum.

Well, more is more, right? The MSP kit was designed for a stock MSP. I'm sure that would be plenty fine for my application but if I'm going to upgrade components anyway, why not upgrade them to the parts I really want? Plus upgrading/modding is the whole part of building a car. Heck, a stock P5 would be plenty for me on track but building this car is the reason why I'm doing it. The added bonus is it will be quick-ish. Like the Lego metaphor again, I liked building the Police Station a lot more than actually playing with it. Ya know?
I'm not ruling any options out right now is all.
