new rotors?

[Dexter]

Mine are poop. Who the hell makes some rotors for us? Anyone besides KVR @ corksport? I think I remember iON mentioning they have rotors...anyone have more info or a price on that? I could use some new front pads too...EBC has part numbers in ther catalog for Greenstuffs for us, but my distributor says they aren't in production. Probably just horse-shit because they are stupid. And then there is Carbotech also.

[instylz]

brembo

[Dexter]

well yeah..... but do you have any info or part numbers ... ??

[unwrittenLaw]

how many miles do you have, and are you hard on your brakes? did you ever have the rotors turned? just curious...

[instylz]

(lick)

[mypfizzle]

i dont think those brembos will work on a msp.. arent the front rotors a lil bigger than mp3 + p5 ones?

[instylz]

I've seen several members sell brembos in the for sale section to which they claimed it would be a perfect fit for the msp as well. Someone please chime in on this so we can all benefit from a clear answer. :)

[AutoBox]

the msp brakes are not regular protege ones..they ar eoff a european model mazda along with our shitty ic lol....i dunno if its front and back but i know we dont got stock protege binders up front (rockon)

[Dexter]

the fronts are 10.9" and the back 11" IIRC. i dont think regular MP3/P5 rotors will work..

UnwrittenLaw: 25,000 miles. I brake hard sometimes, and ive never had my rotors turned. I'd rather just have better rotors rather than turning them over and over. When im breaking, and coming right to the stop, my car moves in an undulating forward and backward motion, as if i was pressing and letting go of the pedal. If i brake really hard, i get no such motion, so this leads me to belive my rotors are warped..maybe im wrong though...

[RyanJayG]

sounds like warped rotors to me... turning wouod be cheap and effective for a while... but I couldn't tell you if the p5/sedan/mp3 rotors would work for you or not... I know the size difference stock isn't THAT off, but who knows?

[Speedplease]

Dexter I get the same thing when I brake maybe its something more then warped rotors? Because I only have 14000 mi on my car. I rarely ever brake hard and i never drove through deep puddles when my rotors were really hot. Plus theres another thread stating info about this pulsating problem. Anyways Wilwood also makes brake kits for our cars dont know if they just make rotors though. Good Luck

[instylz]

would using different size rotors really matter esp if its brembos? I would assume you would get better stopping power on them as opposed to the stockers even though they might be slightly smaller.

[vodapas77]

Sorry guys,

Brembos won't work. Nor will any other rotor they sell for the ES/P5. Well, that's not exactly true. The fronts will work, but not the rears. As of right now as far as I know only KVR via CorkSport makes replacements for the OEM E-Spec rear rotors. I bought the KVRs and I am quite happy with them, but that was before the big price jump. I doubt I would buy them for what they cost now.

[vodapas77]

Yes, it will matter quite a bit. One guy out here bought P5 rotors and tried to put them on his MSP. Within a few miles he had chewed the hell out of his brake pads. The MSPs rear rotors are actually larger than the fronts. That makes for bad juju when you replace them with a set where the rear rotors are smaller than the fronts. The position of the caliper actually forces the pads down onto the outer edge of the rotor. Ouch!

[instylz]

god damn thanks for the info! I almost picked those up too!

Wait, whats the front rotor size on a stock ES/P5? 10.9" ?

I saw the price for the KVR's and thats why i posted this...:)

I could be completely off on that. Obviously a P5 owner could tell you more, but yeah I believe they are the same size. Sounds like it's your front rotors that are causing you the problem, so this might just be the ticket for ya. :)

[MattN]

Greenstuffs for us, but my distributor says they aren't in production.

Please trust me when I say you do NOT want ANYTHING to do with anything EBC. I am not just saying this because I work for Carbotech. Their stuff is so bad, it's dangerous. I have first hand experience with their product. I vaporized a set in 13 laps at VIR. To. The. Plate. 13 laps. Took a call today from a guy that burned completely through a set in 9 laps. On a 2400lb Civic.

Good info. Pads aren't a problem though, ive always got you there

[mspdfreak]

..."The MSPs rear rotors are actually larger than the fronts. That makes for bad juju when you replace them with a set where the rear rotors are smaller than the fronts."Not to threadjack, but if most of the braking is done by the front brakes, why are the rear rotors bigger?!

[Dexter]

I was thinkng the same exact thing.

My bad Dex. Mazda really screwed us for after-market rotors. lol. Unless the 323 is big enough in Europe to have its own aftermarket. lol.

As for why the rear rotors are bigger. That's a good question. Of course 6 mm difference probably doesn't matter much.

[Dexter]

Hm....

[vodapas77]

Hm....
Uh oh... He's up to something. lol.

[mspdfreak]

Makes no damn sense!!

[vodapas77]

But I must say I think it looks better.

[AFaceInTheCrowd]

hmm... i say freak that. i'm getting the whole damn brake system replace with kvr in the rear and stoptech up front.

[mspdfreak]

Just make sure they'll clear your wheels!

[1FASTMSP]

i am just curious what info comes out of this, been wanting new rotors myself

My rotors warped around 8,000 miles, and I finally got them turned by the dealer at 12,000. If you feel that pulsation when braking while stoping at a light, then the rotors are warped.

Front is 10.9", no?

[Dexter]

I don't know what this 'euro-spec' crap is, I looked up the Turbo Diesel Protege brakes in EBC's European market catalogue...

2.0 TD (BJ1) 98- D1125 V 4
257mm

257mm = 10.1"
so, what the hell...
and plus, that 4 means its a 4 bolt pattern...not 5...so how the hell are our brakes 'euro-spec'

[Dexter]

The regular '323' brakes are these:

2.0 2001- D1191 V 5 274 48 24 22

5 bolt pattern and 274mm... = 10.79"

close, but not the 10.9".

[Msp-titanium]

for the bigger rear rotor i think is for
a better front/rear brake balance (shrug)

[srd555]

Hello all,

I just upgraded my brake system and this is what I did:

Since, like you guys are finding out, the MSP rotors are so had to fit in the aftermarket (except for the KVR, which I dont like from a bad experience with another car I had) I decided to see what can be done with the stock rotor.

I had a set of front rotors on my old Subaru impreza cryo treated and they lasted untill I sold the car. Thats 80K without ever warping and I went through 3.5 Mintex 1166 pads (not rotor friendly).

I contacted Bill Groschen @ http://www.frozenrotors.com/ to ask if they had an application for the MSP. the answer was " no but we can run out to the nearest Mazda dealership and pick up a set, cryo treat them and send it out to you". This would cost:

$75.60 for each front rotor from Mazda after tax. ( I checked with my local dealer and they were going for $70)
$56.00 to cryo treat each rotor.

Thats $263.20 for both rotors cryo treated and $20 S/H to Miami for a total of $283.20 shipped. I also opted for the $45 per rotor slotting which brought the total to $373.20.

My next step was to order the Carbotech Bobcats for all 4 corners. All I can say is WOW.

[Dexter]

Good info dude, really awesome...

so a bit under 300 for rotors that should last the lifetime of the car...not bad....

[srd555]

Oh yeah I forgot, the rotors came with a strip of temp sensitive paint on the outer edge.

The color key is as follows:

Red Ambient temp.
Rust 700 deg F
Orange 875 deg F
Yellow 1000 deg F
Pale yellow 1200 deg F
Gray Green 1475 deg F


But after 850 miles of my driving (wrc) the paint is still red. (shrug)

Maybe its those stupid Bobcats stoping the car before they have time to heat up. (thumb)

[Dr.Sound]

wow srd555.......good-ass info!
thanks a lot.

Yes Sir.

[Dr.Sound]

wow

[MazdaSP]

hmm... maybe pulsating feeling in my brakes are warped rotors and not abs?

[Dr.Sound]

abs is really fast vibration......pulsation is caused by warped rotors
\

[Dexter]

Yeah ABS is totally different...

[INGREXCO]

i have just 11702 miles on the car, and my rotors are warped too! i do not break hard at all either,

[Dr.Sound]

every goddamn MSP has f-up rotors....ALL OF THEM
i owned 2 and on both rotors were warped after 6k miles

every person i know....at least here in cali.....has warped rotors.

[Dexter]

Yeah, they really suck up the dick...

[Dr.Sound]

oh yeah, and the scariest shit was driving spicyMSP's car 60 miles down to magnaflow, alone.....with NO brake pads (30k+ miles), warped rotors, and a blinking ABS light.

[instylz]

ouch!

[MattN]

Guys, concerning warped rotors, I'd like for you all to read this link please: http://www.stoptech.com/whitepapers/warped_rotors_myth.htm

It has been *MY* personal experience that the brake shudder you think is warped rotors is uneven deposits on the rotor from crappy brake pads.

As for aftermarket rotors, I'll dig through my book on Monday and see what I can find. I may have something you'll like....

[Dexter]

Ooooh, cool Matt. Hopefully you can come up with something. Otherwise, I'm going to probably get new front rotors, have them cryo'd at a place by me and get some Bobcats..

[MattN]

Explain to me how aftermarket rotors are going to be better than OEM spec ones?
Yep, cast iron is cast iron (rotors are *NOT* steel). The heat treatments the different manufacturers use can affect how they wear and if they crack easily, but no one rotor is really going to *perform* better than the other.

[alexlitov]

Besides, it costs $8 a rotor to be resurfaced at Pep Boys anyway.

Hehe :)

[Dexter]

Explain to me how aftermarket rotors are going to be better than OEM spec ones? :rolleyes: The low speed shudder is *NOT* warped rotors. I don't know if anybody has ever driven a car with warped rotors, but that's not it. The pads are the issue. Besides, it costs $8 a rotor to be resurfaced at Pep Boys anyway. Why waste your money?
hmm okay...

just to clarify...i never said aftermarket would be better than OEM spec.
What does a car with warped rotors drive like? Mad steering wheel shake?

So should i even resurface them? I might as well save that money then if its the pads, right?

[Dexter]

Holy shit, where the fuck did that come from...

What the fuck is your problem?

Since you are so fucking righteous, isnt going to a brake shop and asking if they look 'in spec' being spoon fed too?

The hell dude, honestly, is your fucking problem?

[Dexter]

My what? I dont have a problem...im just asking fucking questions, dickhead. I didn't ask you how to take my car to the shop and ask the dick to look at my breaks, i can figure that out on my own.

I just asked what driving with warped rotors feels like then. Simple fucking question and you turn it into a flame. Whatever dude...

[charles]

Steering wheel shake while braking at high-speeds, as you slow down it slowly dissipates

[charles]

Also you'll be able to feel it in the pedal.

A lot of people have described having problems while braking at low speeds... the way it usually doesn't happen.

[Dexter]

K, thank you for spoon feeding me. It tastes great going down.

[sukegirl_Mp3]

(notcool) hrm ban charles, i say ban him...

yeha the car pretty much shakes...and the sound of two rough metal plates is annoying..i had to change mine a yr after i got my car... stock rotors suck ass

[Dexter]

Hey vodapas77, which pads are you using?

(another 'spoonfeed me' question too!)

[Black Majik MSP]

Frozen Rotors sounds awesome...I'm gonna have to keep that in mind when I have some extra cash.

[t3ase]

there ya go dex.

[vodapas77]

Hey vodapas77, which pads are you using?

(another 'spoonfeed me' question too!)
lol. I'm using Akebano ceramics up front. They're pretty good. Unfortunately, I choose to run EBC's greenstuff in back, I'm gonna change them back to the stock pads once my stainless steel brake lines get here. They have been a pain since I installed them. Noisy as hell and they shed a ton of brake dust.

[MattN]

I contacted Bill Groschen @ http://www.frozenrotors.com/

The guys at Frozen Rotors (aka Diversified Cryogenics) are top notch. Tell them Matt@Carbotech said "Hi".

No wait...don't do that. They may charge you double :)

[Dexter]

Cool thanks. Is that bubblegum flavor? anyways, where are you getting the SS lines from...ive been wanting to do that as well, but corksport says they wont work with the MSP...

[Dexter]

I did some more testing...

at highway speeds (60+ MPH), hitting the brakes will cause the steering wheel to shake back and forth, accompanied with a very faint noise. The magnitude of the shaking is not very high, but it can definetly be felt.

I'm still quite sure the rotors are warped...

[MattN]

I'm still quite sure the rotors are warped...


And I'm still quite sure that if you have those "warped" rotors turned, use a better brake pad, and drive in the same manner that "warped" those rotors in the first place, the problem will not return.

I have done that exact same experiment before.

[Dexter]

Man i feel like im being chastized for thinking i have warped rotors.... : \

[toucci]

Just get your darn rotors turned; a lot of people have had that problem and its fixed inexpensively.

[Dexter]

Its not just the rotors though , as Matt is saying...

[vodapas77]

Cool thanks. Is that bubblegum flavor? anyways, where are you getting the SS lines from...ive been wanting to do that as well, but corksport says they wont work with the MSP...
lol. Yeah, it's Pink Bubble Gum Flavor...

As for the SS lines. I got em from CorkSport. The guy I talked to (not Ben) said they would work with the MSP. Now I just hope he knew what he was talking about.

[MattN]

Man i feel like im being chastized for thinking i have warped rotors.... : \


No no not at all. Its VERY common to think that the rotors are warped. I'm not saying that it's totally impossible for a rotor to warp, just highly unlikely, particularly if you only drive on the street.

I had back to back track weekends at Virginia Int. Raceway a few years ago. I ran one weekend with very cheap Advance Auto pads, and the following weekend with some Porterfield R4 pads (this was well before I started working at Carbotech). After the 1st session with the cheap pads, my steering wheel shook so much I really thought I was going to damage the car during braking. I was *convinced* the rotors were warped. I turned those rotors and installed the R4 pads and went back to the exact same track the following weekend. No violent shuddering what-so-ever. At all!! Zero! After ~180 miles of track driving!!!

I did some research and found that stoptech link I posted below. Case closed, at least for me.

[Dexter]

Alright, cool. Thank you for educating me, honestly. I'll have em turned and get some bobcats. (thumb)

[Dexter]

lol. Yeah, it's Pink Bubble Gum Flavor...

As for the SS lines. I got em from CorkSport. The guy I talked to (not Ben) said they would work with the MSP. Now I just hope he knew what he was talking about.
Yeah, i just checked thier site again, and they must have updated it or something. The CS lines will work, but not the Goodridge. Sweet....

[unwrittenLaw]

so if we get our rotors turned, we have to get new brake pads, correct?

[vodapas77]

Yeah, i just checked thier site again, and they must have updated it or something. The CS lines will work, but not the Goodridge. Sweet....
And you can get them in a variety of fancy colors too. lol.

[KyRaceFan]

IBmassiveMazdaBrakeRecallonMSPs.

My brakes have the low speed shudder, and have had it for quite some time. My car still stops very well at 14k miles, but it is annoying.

All these brakes threads make me want to start a petition to Mazda for these issues.
Enough of us bitched about the hesitation, maybe we can get the brakes fixed too.

[instylz]

so if we get our rotors turned, we have to get new brake pads, correct?
It would be adviseable since the old pads wouldn't be even.

[slug420]

was there any reason for the corksport price hike on the rotors?

I am looking to order a set of 4 next week but im gonna be payin like 200 bucks more than you, plus shipping..........yikes!

[MattN]

was there any reason for the corksport price hike on the rotors?


Being in a retail business these days, anything that is being imported into this country is going through the roof price-wise. The US dollar is very, very weak right now. If their rotors are coming in from another country (Japan, Australia, Italy), that's why.

Another reason to buy Made in the USA.

[slug420]

i dont think they are, i think they're just from canada...

[unwrittenLaw]

here's a good write up on rotors...i put this in a different thread but figured it was relevant here also..

http://www.surrealmirage.com/subaru/brakes.html#gasslotted

[MattN]

canada...

Just as bad. The US dollar is way down to the Canadian dollar compared to a year ago.
