Brake Rotors
Haven't played with the car in a while and feeling the itch again.
Thinking of replacing the rotors. MikeyR was looking into it as well but he's playing MIA atm, so I thought I'd throw it open to other suggestions.
Taka's brake workup has been well documented. Anybody else replaced rotors with a recommendation to offer?
At this stage I don't want to replace the calipers but that's a probability down the track.

I do not recommend the DBA 4000 series.
My rear rotor is just an ugly plate. It burns easily, wraps easily and does not wear as neat as the front Project Mu, which bears most of the braking force. I already machined the rear DBA already.
Alternatives:
You know about Project Mu
Endless
They are both FC forged alloy.... whatever that means
Generally, ANY 2-piece slotted design is worth a go. They are lighter, more able to prevent heat build up, and certainly look cooler.

are they slotted or slotted/cross drilled rotors? what brake pad did you use with the DBA rotors?

... so why waste time on upgrading a few things now which will have to be thrown away when you make the big step anyway?
Just my 2 cents

Thanks for the suggestions so far.
Just to clarify, I do have a set of EBC red stuff ceramic pads that I'm about to pick up (see Sydney Run thread).
I don't really want to spend the $$$ on calipers as well at this stage but the rotors are looking tired. So I wanted some rotors that are compatible with the stock calipers but will also be suitable for aftermarket calipers down the track.
The Project Mu's are probably the front runners at this stage (assuming they're suitable for the stock caliper??) but I'm open to other ideas from those who have already trod this path.
Take the point on the braided lines. That's also a future option I'll look at.
So, any more ideas?

EBC gold they are called. 
P Mu rotors are for stock replacement (for your stock caliper) Dave. They are slightly more expensive than the DBA 5000 rotors.
Is there a Brembo alternative? Last time I check they don't make stock caliper replacement rotors, but is there anything close/ same size? AP does not have the same size, when I did a search for my set....

Also check out Japan Parts because Auto Exe make a set as well.
I have to say though that for simplicity and price I think the Project Mu are the way to go. They are readily available for < $1000 and install is reasonably simple from what I have heard.

As for brembo, I found these a while ago as well but were never sure that they were actually brembos.

Not MIA just been overseas a bit!
Dave, i did a whole lot of research and the Racingbrake versions get good write up's around the forums for a reasonable price. DBA's are over $1000 for the 4000's and as Taka mentioned, not great.
I'll email you.

Racing beat slotted
Looking at the two piece slotted
Say $300 US shipped is $1200 USD for 4 and it is about $1530 AUD.
hmmm... it is not really cheap. Just a touch cheaper. They don't look too bad IMO. Give it a try and let us know.

I bought the ones at the bottom of this page yesterday.

The picture is of drilled and slotted, but I bought only slotted. Click on the link for each of those for more info.

Happy to piggyback onto your research Mike. Let me know what you've come up with and we'll talk GB options.
Thanks to the rest of you. Really appreciate your efforts. As usual, I'm now totally confused as to which product to go for.

Replacement OEM rotors front and rear from Online Mazda parts cost $US 510. Add 50 for shipping and the exchange rate works out at about $A750 for all four. They seem to be a good rotor for street use, but I do not track the car, so I will leave that to others for comment.

$50 for shipping. I wanna see that! They are kind of heavy you know. Even sea shipment from USPS is $60 for just a rear and front rotor.
I place a quote on USPS for 35 pound. That is one front (18lbs), one rear (12lbs) and packaging.
http://ircalc.usps.gov/intl_speed.as...ds=35&Ounces=0
That is $60 US!
it will be 120$ to ship, and take 6 weeks 
That is why I say forget US - too far. But still work out cheaper I think

Dave, hate to be a poo-head, but do you really need the new rotors?
I mean I understand youve done the suspension mods now.. the rims, ur not into any other cosmetic mods.. hmm werent u only going to keep the car for few yrs ?? is it worth spending all this money on new rotors when we know we wont be making our money back. If you really got the mod bug, maybe something thats a little cheaper?
You could be our little lab rat and go have some porting working done to the engine instead of S/C and Turbo... ? lol I cant really think of any other mods, so I can see why you are thinking the rotors - but at the end of the day theres heaps of guys here that continue to track the car - and done many track days - that are perfectly happy with the stock brakes/rotors.
Although im not the 1 to really talk people out of mods....... lol just do what you want! haha
