Big Brakes Finally!
- Thread starter 122 Vega
- Start date
um. I tend to lock up my brakes, different wheels depending on the corner. purely driver error. But I found that this littil thingy helps with the "balance" no mater what pads im using. oh and a pair of these other thingys helps with the fad and wear.
but there is different ways of doing everything. Remember that this is for fun not a scientific journal(fight)

The specs for the Mazda 3 SP23 rotors are almost identical to the P5 (except of course for the diameter - 258mm compared to 300mm) according to DBA. My only worry is offset 48 versus 52.5 and the position of the front caliper in relation to the strut (the Mazda 3 calipers are forward of the strut). Otherwise, I would love to see some expert opinions on this.

Please provide more information!!!!
What more information? Isn't it common knowledge that all 6s brakes fit on the Protege? Here in Quebec, you'll see a lot of Protege with Mazda 6 front brakes. My race car have them all around, since I don't have a hand brake, I can put them in the back. The 2006+(bigger) fit and the Mazdaspeed 6 as well.
Here's some pics of the ones that was on my race car:
completly bolt-on! I did that in 2005, this is why I thouht it was common knowledge.

thats big!
You HAVE to use the Mazda 6 calipers if you want the disc and vice-versa! You don't need to change the master cylinder. You can upgrade it to the 92-93 929 master if you want, but it's not needed.
Use the same brake lines, preferably Russell SS lines! No adapter needed.
If you can read french, I made a huge How-to on clubprotegequebec.com LOL

The car to which he refers was previously owned by Ron Williams, then Bridgette Olson (both trophy winners at nat's in the car) and they both ran Hawk HP+ all around. Of course I adopted this setup along with the car and flatspotted plenty of rear tires learning to drive and eventually decided the rear brakes were just too strong. Solution? I ground about 1/4" of pad material from either end of all four rear pads. Problem solved. This calmed the car down a LOT and allowed me to stop much faster than before, with much less rear wheel lockup.
Even so, with the same brake setup now running in STX I will still emit puffs of smoke from the rear wheels upon hard breaking and corner entry, however it does not affect the stability of the car. It does allow for very predictable and controllable trail breaking.
As to upgrading the fronts at all...for autocross I always wonder why?? First off, the stock brakes with good pads are MORE than adequate as most that have driven my car and subsuqently locked up the wheels and/or left teeth marks on the steering wheel are always amazed the only modification is the pads. Even for track days with good fluid and bending the heat shields back they are surprisingly adequate, even stopping from 100+ for 20 min sessions in 104deg weather.
Second, weight...122 Vega, I seem to recall in your STX build thread that you were anxioisly awaiting your alloy lug nuts to help reduce weight? That larger rotor has got to weigh signifigantly more, and the weight is further from the center of rotation. For autocross I can't imagine the advantage of better breaking would outweight the larger rotational mass and unsprung weight.
This is precicely why I haven't even bothered upsizing the rotors, nevermind the fact that I don't need more breaking, I'm already grossly underpowered conmpared to the MSP and others in STX, the last thing I need is more rotational mass.

Is that Ron Williams from Salina, KS?

I belive so, the same Ron Williams that won GS in a Mini this year 
Makes me feel special to own his old GS car

So would the MS3 brakes fit the protege?

If it is the same Ron Williams (and it probably is), I remember seeing him at an event in Salina and I was amazed at how fast he was in that car (red mid-90's MX-6). The stock suspension would ROLL like crazy as he threw it around in the slalom with his sticky tires on. If he didn't set FTD that day, he was close.

Oh man did it roll, it looked a lot worse than it was, when driving the car it was actually controlled very well, and didn't feel like it was rolling anywere near as much as it looked like it was.
Even in tight transitions it was amazingly controlable...unless you screwed up
