Teaser: M-Tuned 10.9" Rear Brake Kit
 

Just finished installing the M-Tuned Rear Brake kit on my personal Miata as a quick test. The kits are 99% ready to go. Just have to machine one small spot to allow some extra clearance due to caliper casting differences.

Hope to be shipping by NEXT week.

Our Web Price for this kit will be $109 + Shipping. Will include all washers, bolts and brackets needed for the installation.

Hope you like the pics and don't mind the teaser. Car looks great with the 11" Corrado Kit on the Front and the 10.9" Miata Sport Kit on the Rear.

I'm in. Where do I order. Not on website yet.

what rotors will this kit be using? miata sports? (impossible to find here, unless you want to pay $300 a set) Will they be ventilated or is the rear caliper not big enough to run ventilated rear rotors?

sport rotors from the rear of the 01-05


(btw, i called my local autopart store (Congress Auto) and they have them for 26$ each)

Are you sure they were not quoting the price of the regular rear discs? That price is successfully low.

i said, "u sure that is the Sport edition, i know they had more than one size." he said, "i see the standard brakes as well, but this is for the sports."

i will buy a set to verify, and if any of you want them, let me know, i looked at kragen/orielys site they have them for 46$

NAPA now sells rear sport rotors for the mid $30 range. I'm using them in this picture.
They are no longer priced in the $300 range.

hell, I already pay $60 for a pair of 1.8 non-sport fronts. The corrado set ran me $160 for a set. If this kit would utilise a set of more commonly available and cheaper rotors I would be all over them

I already have a 1.8 proportioning valve on my 1.6, would it balance out if I went with the front and rear upgrade you sell?

Wow.. Most people pay $25-35 a piece for the Corrado rotors.

The Miata sport rotors are an inexpensive rotor available at most major Autoparts stores for in the $30-$35 Range. I have researched to no end and can't find a 4x100 rotor which will fit on our cars and with our caliper which is in the 10.75"-10.9" range like the Miata Sport.

Can't use a ventilated rotor as it won't fit within our caliper bracket. Heck, even the Miata sports where a hair different in spacing, but we had the room to make it work.

I will have the web guy update the site next week to add it as an available product!

The Rear Kit certainly helps balance for the 11" Corrado front kit. You have the proportioning valve so you can even tweak your setup.
I drove my 2000SE all day with both of our kits on and I love it. My GF was getting fed up of me doing highspeed braking, but I told her it was R&D :)

So what does a full kit run? Just need 1.8 caliper brackets all around?

How can I tweak the stock prop valve?

You don't, you get an adjustable one.

Damn it! I just bought new rotors in the rear when I ordered my corrado ones. Oh well, guess i can just use them on another car. I'm in

Marc, have you thought about an entire "package"...

Front 11" kit: $99
Rotors: $60
Rear 10.9" kit: $109
Prop Valve: $70
Stainless Lines: $110
Green-Stuff's or Hawk HPS: $140
Fluid: $10
Total: $598
Now add shipping... you're talking $650!

Kits from you, rotors from Napa, valve from FM, lines from AA, fluid and pads from Good-Win... you could corner the market by throwing it all in one box for about $600 shipped with a good set of instructions for NOOBs... just a thought.

from what i see this has calipers and brackets.

The brakes look good but man i'd rather have those TE37s :)

I was simply quoting him as saying I could tweak it, I know the stock valve has no adjustment.

I made a mistake.. Thought you had an adjustable one. Sorry :)

yes...use a sealant on the npt adapter threads so your life is easier than mine was.

I'm not overheating my rear 1.8 brakes on the track with a properly dialed-in bias valve...so why go with this mod? Is it just so the rears can look big?

No matter how fast you are, it means nothing if you cant stop. Can never have to much Brakes IMO. It usually only happens once when your messing around going way to fast for that turn one off the front stright and that brake pedal falls right to the floor. Knowing the session before the brakes were so hot you can lit a cig off the rotors and the brake fluid was already boiling over. WHAT DO YOU DO? kiss the car goodbye? and if you save it? change your shorts and do a brake up-grade asap :) I did the both while yelling OOOHHH shit! lol it many never happen to most but to the few that have felt brake fade know what i am talking about, and its some scary ass shit. my .02 cents.

Cause you drive like a girly man. Also explains why you were not overheating your engine :laugh:

I think we need a Group Buy Package Deal on an M-Tuned front and rear conversion kit!

You went back out after knowing that you got your brakes that hot and didn't bleed them? It takes all of what 15 minutes to bleed all 4 corners?

I am not saying that these aren't merrited, but your justification is far from rational.

Post #18 above anybody?

So what is the point of doing this? I see absolutely no merit in this mod.

These are really just for track cars or for those who really need a big brake look through the back wheels. Guys, 1.6 brakes with race pads have been proven to be great for SM (N/A) racers. People usually upgrade to a good street pad and 1.8 brakes when they're turbo'd, and 1.8 brakes with race pads of it's a tracked turbo'd car.

These kits are for the racers who have wide r-comps, race pads on all four corners, 11" rotors in the front, and their adjustable proportioning valve can't get them enough rear bias for their particular driving style.

I hate to go all m.net on everyone (racers excluded), and possibly sway buyers from m-tuned's great product, but don't buy these if you only drive your car on the street! It took me five 60-0 runs to get a little fade out of 1.6 brakes with hawk HPS+ pads (that's 60mph-0mph-60mph-0mph-60mph-0mph-60mph-0mph-60mph-0mph, slamming the brakes each time almost to the point of lock up). You will NEVER do that on the street! Well, I did, but it was a test. You'll only be adding rotational mass to your back end, after you just spent that money buying the ultra-light-can-actually-see-through-the-spokes-and-see-your-brakes-wheels. Just my :2cents:

Track cars don't need these brakes....

With a prop valve, you CAN get enough rear bias; even a former go-karter who likes rear lockup to help rotate the car entering corners can get enough rear bias.

Hawk HPS and HP+ pads are two different kinds, so not sure which you were using, but either way that's a street pad, so fading them is not surprising.

Agreed on the adding un-sprung rotational mass to the car. Completely useless.

Neither do I. I hate to say it, but this is purely for looks and peace of mind. Larger rear brakes are absolutely unnecessary.

Well I was assuming discussion have gone on that I haven't read where larger rear brakes were required, I know I don't need them, I just figured others did.

I was running Hawk's HPS pad, my apologies for the confusion. My point was that with street pads and 'puny' 1.6 brakes it takes a lot of abuse to get any fade.

I don't mean to sound argumentative, we're on the same side. Perhaps we should drop it though, help mark make some $$$.

If it was a useful product (like the corrado front rotor adapter), I'd be all for it.

I just don't want people to think they need bigger rear brakes for ANYTHING other than looks.

I wonder why Mazda did it if it weighs more than the standard 1.8 brakes.

I'm going to add my :2cents: from this past weekend at barber. I've got the 1.8 upgrade on fronts and rears. Slotted rear rotors, $30 front rotors. Rear pads are Hawk blacks, Fronts are a race pad from FM, and an adjustable proportioning valve. Brakes were bled before the event so that the fluid was fresh (synthetic DOT3/DOT4). My instructor who was also driving his GTA car this past weekend drove a few laps in my car to show me the capabilities. He said the brakes were fantastic. He thought with a few sessions he could get within 5sec of his gta cars lap times. I completed 2hrs of total track time.

From my limited real world track experience, this upgrade doesn't seem necessary.

Marc,will this kit fit the 1.6 cars,or will we need to purchase the 1.8 calipers?

Yeah just giving Hustler a hard time. He was going faster than me at the MSR track day.

I have managed to throughly fade my stock 1.8 brakes in the twisty roads NW of San Antonio in the Hill Country. They faded to the point where I had to stop and let them cool off, and they were definitely outgassing (I could smell them). But this is on low-speed twisty roads where there is not much speed, or time, for them to cool off. IIRC I brought this up in a previous discussion.

At the track day I did not push my brakes real hard, and in fact backed off a bit as soon as I felt them start to fade in a session where I was braking more aggressively. This is with fresh brake fluid, but stock rotors and ceramic street brake pads. No ducting. No prop' valve.

Soooo... I was seriously considering going to at least the Corrado rotors on the front. It is interesting to hear Sav say the rear upgrade is not needed for the track. I do not have enough track time in a Miata to argue that point one way or the other.

Bigger rotors wont help if you are using THE WRONG COMPOUND PAD

Yeah I am definitely not using a racing pad right now. It is my DD. I should probably pick up a set of pads for the track and swap them out as needed.

Until you are demolishing race pads on stock-sized rotors, larger rotors are not necessary.

I only upgraded to the Corrado fronts after doing this to a set of XP12s:

Attachment 205036

I have destroyed a set of XP12s, a set of XP10s, and a set of Raybestos ST43s, and my original set of rear Carbotech XP10s still have 50% of their life left. This is WITH a prop valve.

Why did we make this product??

- Kept getting asked for a larger rear brake by both customers and my vendors. They wanted something to match our 11" Front Kit.
- Assists with F/R basis when installing the corrado kit on the front of a car without an adjustable prop valve.
- Some people would like a larger rotor for looks when running 16"+ wheels.
- If you are doing brakes and already buying new pads and rotors, why not go bigger with this kit?

I know the rear kit really helped balance out the front kit on my 2000SE. I'm also working on a way to mount the larger sport brake pads on a non-sport car. Giving even more braking performance.

Not all cars are track cars. I don't want to use noisy-ass race pads on my DD yet I still want decent performance. I assume that's why they come stock on the mazdaspeed.

Yeah.. I've got one customer who is an Autox guy. He needs the big rear rotor as he needs more rear braking and can't use a more aggressive pad as he does not get the required temps on a short autox course.

Our kit is what he feels is the answer.

Stock brakes are perfectly good for street use. If you are upgrading your brakes for any reason other than track use, it is for looks.

Obviously you haven't pushed your car very hard on the street.

Yeah, like I said, I have faded mine on the road.

Obviously, you two are using the wrong pad for the type of driving you are doing.

Anyways, I'm done with this thread. Good luck with the sales.

Other cars with brakes just for looks:

2006 lotus elise 11.1/11.1
2009 porsche boxter 12.52/11.77
2009 mx-5 11.4/11.0
2009 honda s2000 11.8/11.1

These manufacturers should change their pads too.

My car with 250+hp is better off with brakes off a:

2009 civic ex 10.3/10.2
2009 corolla 10.8/10.2

:jerkit:

group buy or have a special pricing for the F+R brakets as a package!

We will only charge shipping on 1 kit and the other will ship free.

want me to post the vid where you get skull-fucked in the last session of the day where my turbo is hanging off the manifold?

Damn dude your e-thug skills are slipping. It took you a long time to respond to that :loser:

xoxo

Marc, what's the ETA on this? Still not on the website.

What about upgrading from 1.6L brakes to the larger 1.8L setup?

Please let me know which head light kit is on this car. I love it! I MUST HAVE IT! LOL

Thank you.
