That shouldnt worry you too much though. Since you gonna make a custom setup you might as well use the hydrolic pump

i highly doubt these are mazdaspeed... i have a few cataloques of mazdaspeed and none offer rear kit for the fd ... especially on that price...
You find second hand mazdaspeed front brakes for 4500-5000 from japan..

This is the setup I'm running on my FD. Brembo BBK in the front and the '99 brake setup in the rear. Haven't tested it yet, but I imagine it'll be fine for what I require.

i would like to get an aggressive setup for road racing, how ever i want to retain the hand brake function, since i would like to get into drifting more. im getting better, but havent been using the e-brake but rather do it at like 20mph rev and drop in 2nd to brake em loose.

heres my new brake kit
you need to measure ur car in order to make sure if its properly, in case it doesnt you may add spacers. But it all depends to your rims. You need at least 2 inch clearance
328x35mm brembo nascar spec rotors 48vane
alcon nascar xt calipers (a huge ****)
anodized aluminum rotor hats
wilwood polymatrix h compound pads 30mm

how about a set of c6 z06 brakes? they are 6 pot in front, and 4 in the rear? the z06 has a handbrake that would mean there is no reason for a caliper specifically for the handbrake and one for regular use. i will check when i get to work tomorrow, and post the results.

I have Stoptech's in front 332mm x 32mm, with the (RB)RacingBrake rear kit 322mm x 20mm.

Its a decent track set up without having to mess with a proprtioning vavle, though with a proportioning valve it can be tuned to anyones particular style of driving for the track or street. Another advantage of using the stock rear caliper is your unsprung weight doesn't increase too much, no messing with additional mechanisms, and no worrying about reliablity issues.
I like this set up, it works well, I recommend it!!

The pedal feel and response is definitely NOT of an OEM car. With the stock brake you can SLAM them down RELYING on the antilock, and the brakes work fairly well. IT SEEMS WITH THE STOPTECH'S IF YOU SLAM DOWN ON THE BRAKES AND NOT ALLOW THE WEIGHT SHIFT TO THE FRONT, THE WHEELS INEFFECTIVLY PULSATE TO STOP, AND YOUR STOPPING DISTANCE SEEMS TO INCREASE. In my opinion its better to drive the car like it has no antilock, applying impeding lockup techniques. Antilock DOES NOT seem to be as effective with the big brake setup.
Don't get me wrong the stopping power is much stronger, With the bigger brakes I noticed I can brake later on the tracks used to visit, . Brake fade is definitely decreased, At the track I would find a brake marker and apply it as such, by the end of the run, and esspecially at the end of the track day that brake marker would have to be adjusted a great distance to compensate for the brake fade. I can now consistanly use the same brake marker wihout adjusting.
I used to wear pads out real aggressively, now its barely noticeable at the end of a track day.
As far as the larger rear rotors, there's not really any significantly huge difference especially for the street and the average track day driver, though I find if you push the vehicle to its potential limit and apply left foot braking or late braking the rear seems point and shoot more consistanly compared to the stock rotors especially when you've been doing it lap after lap. Also for drifting or gymkana, I find the E-brake is SLIGHTLY more responsive with the larger rotors.
I think the rear rotor upgrade is not essential, though with the feeling of more consistant performance it gives you more confidence to drive closer to the vehicle's limits.
Everybody's prefereces are different, these are just my personal findings.

(a comparison of my old cooked OEM rear calipers and the '99 RZ caliper I use with a 315mmx20mm Precision Brake two piece rear rotor. I used to crack rear rotors regularly att he track...not anymore.
And as an aside the key to brake longevity, IMHO, is not to add bigger rotors and more mass but to add better cooling. Ducting is the key.

FWIW, that Racing Brake rear caliper adapter is essentially the same as the OEM '99 RZ rear caliper.

Great info in general !! About the brake ductiing....do you have any pics of your ducting? I love to get some ideas to adopt your recommendations....

I am quite limited in my ducting options because I use a '99 front end. But I think you get the idea. Those of you with aftermarket front ends can scoop much more airflow than I can and will therefore benefit considerably more. I added the ducting after I cracked a set of AP rotors on my BBK.

RE: what ptrhahn posted, AtomicRex/HiSPec calipers:
http://www.hispecbrake.co.uk/sierra_2wd_45_deg__up.htm
Even has the right angle for the e-brake boss fitting apparently. Planning on making an adapter to fit to my Racing Brake rear rotors, but have to add that to my laundry list of things to do later.

^Ok. Let me clarify what I meant by "essentially the same." The '99 rear calipers are NOT IDENTICAL to the Racing Brake rear adapter. The Racing brake caliper will allow you to fit a rotor that is 4-7mm larger in diameter. The '99 RZ rear caliper can accept up to a 318mm x 20mm rear rotor even though I only use a 315mm rear rotor since it's a standard size. I guess what one can take away from this is that there are two of these kind of options available. The slightly larger Racing Brake "kit" with improved rotor design, but using only a caliper adapter the more expensive option at close to $1000. On the flipside the '99RZ "package" would be less expensive for those more cost conscious (sorry I don't recall what I paid offhand) and would include new calipers but but with slightly less engineered rotor design.
Thanks for prompting the clarification.
