How many US of A FD owners out there that have SP/RZ/Spirit R brakes?
I'm just curious... How many of you in USA own SP/RZ/Spirit R brakes?? This is the larger diameter rotor brake system..

Here are pictures of the rotors..
Rear RZ vs US FD stock rotors... you can clearly see the thickness difference and diameter.
Here are comparison of Racing Brake rotors vs. RZ vs. US FD stock rotor.
Here is a picture of my RZ on my MB FD.. Wheel is gram light 57c 17x9.5s. It fills up the wheel well.
Also, I'm hoping to get some DBA rotors for my RZ and wanted to see how many of you might be also interested.. They might make the 5000 series if enough people are interested.. Personally I prefer DBA over RB and I think it would be great to get them to make the 5000 series rotors for the RZ's.

Julian,
You are correct. I'm currently trying to get a set of their SP rotors for my 7 and I'm getting the 5000 series rotors for the RX8. I've heard great things about them and I like the history behind their product.
Here is a cross section of their so called "Kangaroo Paw" vents.

I like the plug in Bryan 
Here is my custom drilled RZ rotors.. stock blanks crossed drilled and edges beveled by David Garfinkles.. Its also harmonically balanced. FYI, David could do this to any rotors..
Look how nice of a job he did! Maybe better than the Spirit R rotors

Too bad the Mandeville big brakes aren't available anymore... It seems like the RZ brakes are probably the next best thing if you don't go for a full BBK.

I run the RS/RZ rears on my current track car. Rotors last longer than the stock 93-95 and they help even out my brakes in the front. I haven't decided yet if I'm going to order replacement stock rotors or send my old rotors to Coleman Racing and have them make replacements.

Those DBA larger size rotors are still unavailable as of yesterday, although they've had a catalogue listing for years. Not sure I'd place too much credence on them supplying the original SP ones either, as Mazda was making them in that time frame. If you wanted to go two piece, they do have a rotor you could use, suitably modified.
A local guy here does do a mandeville style spacer for the small calipers, with your material cost advantage and manufacturing apparently in the doldrums over there, I'd be amazed if you couldn't get a run done for a lot less locally!
If you do get Coleman to do a replacement - two piece, I'd be interested in rears....wanted a sample to work from, which would be a killer on freight sending there and back.

DBA Australia once sent me to the US distributor to KNS Brakes. That seems to have died. As to sthe SP and Mazda, mazda developed the Big brake set for the SP race car and DBA made the rotors; The Series 7 JDM made rotors came later.

ok - so you really want a 2 piece front - hopefully not too expensive - and a good rear to match or just stick w/ the M speed one.
As far as a rotor ring - that is the hard part as it requires tooling or a cheap Coleman that gets machined down -
I will see if DBA has a ring that can be used - and if so - I can get hats made.
DBA has the drawing for the 1 piece that tells me what I need to know. DO you think I should try to make this thing? For me - 5-10 sets to start is plenty of business to go after.

Mazdaspeed USA still offers the JDM spec part and I assume still offered worldwide (at least for now), but Japan is dropping performance parts for the car like flys. We just want a better performance option (2 piece) and realization that a rotor is a regular maintance/wear part not a one time upgrade purchase.

I see
I shall ask to see what the availability of the SP sized rotors are.
If a track guy had the SP brakes - where would he get rotors now?
