A TSF will just tell you the LSD failed not how specifically. BTW How do you have access to each individual case?
You don't know what you are talking about here, so stop...

What does this mean? Still insisting it's driver error that caused failure?
Well then there are 7 people that have had their LSDs replaced, so all 7 of us can't drive then... (jerkit)
I'll be nice here, but if you can't understand what I am getting at, then I don't know what to tell you. If you explain how your differential broke, then it is easier to determine if it was actually mechanical error. But hey, since you read into everything I say, believe what you want.

Grassroots Motorsports? Real, big time racing info there. I have better things to do than go to a book store and look for a magazine about auto X when I don't even auto X.
It's obvious you don't want to learn jack about real performamce issues and enjoy reading Primedia junk. That's fine. If you don't want to learn real tech info about stuff going on with your car. Stop crying when stuff breaks. If you had an idea of how it works and then what iot is supposed to do, you would be able to better figure out why something broke.

BTW, it's not just about auto crossing, but then again, you would know that if you actually read it...

What's so inconsistent about 7 LSDs failing? That is what this thread was for till you and another asshole accused everyone with a broken LSD of driving like morons.
Oh why don't you just stay out of the MSP threads when you DONT HAVE a MSP? You wont have to hear us whine or b**** or cry about our problems!
Name calling, nice. Seems to me you've been the asshole when someone has a differing opinion than yours regarding this issue.

The number seven is where it is inconsistent. How people drive is inconsistent. Stop being a moron and understand what I am typing please.

And, just what I expected, "You don't have an MSP stay out of our threads!" BS...Grow up. I am a memebr of this board, longer than you, and have every right to read whatever the hell I want on here.

Why don't you sell your MSP, then I won't have to read about you crying because something broke...


Someone told me once a long time ago, "There are no problems...Why? Because, if you have a problem and a solution, you can fix the problem. Then the problem is gone. If you don't have a solution there is nothing you can do, so its not a problem. Everything else is just bitching..."

Where are you in this?

No more back and forth s***. State the facts. If you don't have any valuable info to add, then you should think twice about posting. Not singling anyone out.
 
Yes, being on this forum longer means jack s*** to me. You still have a MP3 and have no legit reason on speaking about the MSP since you don't own one and have not experienced these problems firsthand.
(monkey)

I have no reason to read their mags for tech, but to compare performance products. I know the how the mechanics of an automobile works. Might you go invest in a class in automotive repair instead of reading everything you believe in magazines. The class will actually go into detail. You are the typical magazine racer that believes what you read instead of actually trying it yourself.

Look inside the differential of the MSP and compare it to a Quaife. Which one is more solid??? The fact that people have driven differently and these LSDs failed under each different condition shows its not very durable at all. Why dont you quit living in your bubble where cars are perfectly engineered from day one.

Face the fact that lack of engineering and poor quality of materials is the demise of these LSDs and tranmissions. It's poorly thrown together and installed by poorly trained port installers which is another reason why many of the aftermarket parts on here failed such as the loose connections on the sub. Fact is this car is not made for High Performance. Mazda sold it that it was and they better take it up the ass and deal with the failures.

Oh me "bitching" about this problem will just help other people when theirs fail. All I did here was let this problem be known. You came in here pointing fingers like the other ass in the beginning of this thread.

I don't want to be negative but I count on other LSDs failing. I also believe you mean TSB not TSF.

Why don't you sell your MP3 and get a MSP b/c your obviously bitter that some people don't care for the MSP as much as you do. Then you can have your own and baby it all you want, and when you have problems, we can all tell you suck at driving, ragged the s*** out of your car, and quit bitching cuz no one wants to hear that your car has problems because it's your fault.
(fuoops)(blah)

I posted on this thread because I have the Mazdaspeed Limited-Slip Differential. Other people who have posted with MP3s on this thread either already have the Mazdaspeed LSD as well or have considered buying one.

I don't particularly care where the argument started, just please stop arguing.
 
Good job, you'll wish you spent the extra money for a Quaife instead. With the amount of $ you spent on your car I would have.

By putting the MSP lsd in, you might as well have put a Phantom Grip in it.

Typical...You having no knowledge about why the dif broke makes you a relaible source?

Did you test the metal, did you look at how it tore/broke? Get off your holier than though I own an MSP BS and grow up...

You know me from a needle in a hay stack jack ass. A class will not get into as much depth as the magazine has. Yes, I have taken a class...

Compare some more apples to oranges. The Quaiffe and the TSF units are completely different in how they operate. And the Phantom Grip isn't even considered a differential. Compare some more stuff you know nothing about.

Your opinion is not FACT!

TSF, the name (shortened) of the freakin' company who makes the diferential you are railing against. I don't doubt you that yours broke. I never said that. I asked a few question to try get clarification about how you use the car to see if that might give some clues to how it broke. Then you flip out.

I have no issues with the MSP. My car makes better power as is than the MSP. So, why would I be jealous. I think you have that stupid MSP owner attitude that your car is better than all. I had a turbo in my MP3 before the MSP ever came to market. I knew about the MSP over a year before it hit the dealers.(weakest)

So quit your bitchin'. You hate me because I have a different attitude about this. While you continue to b**** about it and not offer up any real solutions to the problem nor post facts about how the dif was built or what metal it was made of, you claim to be the expert.

Pull your head out of your ass and look around. Your opinion is not fact.

I have no knowledge? Look at the damn pics. Pictures speak for themselves. The LSD split in half at the drive gear. You are the only tool who insists it's a sturdy unit. My holy MSP BS? Are you the ******* idiot who cant read I'm bashing the car I drive for being a POS and breaking?
(uhm)

Oh and before you edited your post you said this
Believe or not, I am working on getting a hold of TSF to see what they say about the failure...
For one thing you might to say the company name in full b/c I mistaken that for TSB.

It's already been stated this LSD is weak at where it connects through the drive gear. Maybe if you would pull your head out of your ignorant ass and go look at all the failure pics posted. All the other LSDs have failed at this location.

Your car makes better power than the MSP? Care to post some dyno curves?
I do not have the stupid MSP owner attitude. I don't think my car is a damn super car. It's a 20k Protege for crying out loud. You have the jealous MP3 owner attitude because Mazda made your car again but with a turbo killing your car's value limited production run making it less desireable. Haterade, DRINK IT! (drunk)

A class will not get into as much depth as the magazine has.
Please find me a mag that goes into the detail of tearing down an engine for rebuild. (blah)

Apples and oranges? It's B/C one LSD is better than the other dipshit.
ENZO VS MSP. Which one is perform hands down? People pull that excuse b/c they don't want to face the reality one is better than the other.(screwy)
Look inside the LSD of the MSP:

MSP LSD - Spring loaded clutch type differential

Phantom grip - disc type limited slip insert basically converts to a clutch type(Disc plates exert pressure against spider gears using spring pressure to regulate the amount of slippage at the wheels)
The difference being one is a full unit and the other is a conversion.

QUAIFE - gear driven LSD (no plates or clutches that can wear out and need costly replacementno plates or clutches that can wear out and need costly replacement).

You decide which is more solid dipshit and why the quaife is higher quality.

It's not my job to test what metal is durable enough for automotive use. If it was I'd be designing these things and engineering my own so it wouldnt split in half at the drive gear. If you knew anything about how things work, you would know the weakest point in any object breaks first. It's already been discussed the LSD weak point is at this section where all the LSDs have failed. So STFU about something you know nothing about and
(getout) .
 
well my MSP diff is being welded tomorrow morning.. costing me a F***load too.. my quote was "a couple hundred" so we'll see what it ends up being... the diff has to be cleaned really thoroughly around the weld area.... and then he is going to lay careful TIG welds all the way around it. It certainly won't break there to be sure.. just have to hope it doesn't snap on the inside anywhere...

In the end I figure it won't likely break or wear out in the near future at all with the effort I'm putting into protecting it... combining that with that fact that even with a few hundred spent on reinforcing the diff I'm still only paying just shy of 700 for the diff versus 1000-1200 for the quaife I'm still basically ahead in the end... So I guess i can't complain... it just wasn't what I thought I was signing up for when I bought the diff... but since I race nearly every weekend and am running close to 200 whp... I figured I'd better do it right rather than get stranded a couple hundred miles from home with a broken ass car.
 
i'm done with this thread arguing with you is like competing in the special olympics, no matter who wins you're still a retard.

Then why did you start arguing and name calling? Seems to me this applies to you more than me.

'Tard...Did you do the metalurgic studdy to see if it was merely a bad batch of metal? Did you examine how the metal broke in detail to determine exactly how it broke?

NO! So don't make BS claims that the unit is a piece of crap, when you don't know!

Your the MSP owner, if you don't know who makes the stuff for your damn car, then don't call yourself an expert.

Simply becuase something breaks, doesn't mean it is a piece of crap. Even your coveted Enzo will break. But it shouldn't according to you becuase it costs so damn much, right?

Comparing the two completely different differentials and a block of metal is assinine when it comes to quality. Each unit is going to be built becuase they work in different ways. To say the Quaiffe is inherently better becuase it is more expensive and built completely differently is retarded. Just like your Enzo-MSP comparo.

Comparing the two differentials and the block of metal for effectiveness, that could actually fly. As there are benefits and disadvantages to using each different type of differential in different cars, situations etc...Some would argue, the block of metal (Phantom Grip for your dumbass) is a waste of time. Others would say it works great if that is your only option.

Do see the difference in what you are arguing? No, of course not, becuase that would require you to swallow your pride and admit that you are partially wrong about the BS you spew.

And, as far as a class vs magazine tech goes, there is a difference. Knowledge of how to work on something is different from knowing how it works and why.

People work on things all day long without knowing how it works. Look at Jiffy Lube for example. Knowing how the different types of performance differentials work in front-wheel drive cars is something that I have neever seen a class go into. But, i suppose the class you wnet to did, making you the all knowing god of MSP-dom that you are. Right?
 
(blah) (bird) You're still a fucktard.

Go ask Tri-point which LSDs they use in their race cars. You read Grassroots magazine for the budget racer. Keep using your cheap half assed parts. People serious about performance don't skimp on parts.

Then why did you buy an MSP ass clown?(hi)

You skimped on price and your car breaks all the time...Why didn't you buy a real performance car?

Keep you rhead in the clouds and ignore the fact that different types of differentials are used for different types of racing. Speaking of Tri-Point, why don't you ask them how often they have had motor failure? Say, those motors cost a small fortune, they shouldn't break?

Dip s***...

PS - Why did you come back? I thought you were staying out of this thread...

PPS - Once you again you show your ignorance about what is covered in GRM with your comment. What magazines do you read? SCC, Turbo?

So... How's you're Ferrari?

You guys are pretty funny. You'd have thought you were driving a Ferrari or something. The car costs a dealer like $19,600. You have to figure, Mazda is making 5-10K on the car. So you bought a $10-15K car. It wasn't hand built. Every part wasn't examined. Nobody hammered your car on a track after it came off the assembly line.

You want higher quality?
You want no questions come warranty time?

Then step up and spend some real money. Like at least 50-60k$

Pick up a Boxster S, or a Corvette Z06, or a BMW M3.

It'll drive better, and, the dealer will be much nicer.

Oh no wait... you can't... cause you a broke a$$ M'r F'er.

We got a good deal on this car, there are few FWD cars that can
match its handling... even with an aftermarket setup. Handling makes a sports car, even an economy one. In the meantime, quit driving your car like a four year old, and complaining when it breaks because you dumped the clutch at 5k at a stoplight 50 times, and the first time in a long time that you didn't... the LSD went out.

I work at a dealer too... I see honest breakage, and I see idiot drivers that bring in a car with a leopard spotted flywheel and NO clutch material left, not to say anything about what their front tires look like.

I've seen them with multiple thrown rods from someone misshifting and overrevving the motor.

I've seen the factory eat $100,000 worth of motors at least, on cars that were broken by their owners... not by design problems.

Most dealers are very jaded, and with good reason.

Not because they are out to get you personally. After all.. they make money on warranty work! They lose money by turning it away!

It's because lots of other people (maybe you!), beat them up because you did something dumb.

Keep in mind you will destroy a million dollar car by driving it improperly.

Take some responsibility when you screw up, and demand the dealer take his lumps when you're not at fault.

In the end, it's like the billboard in Rocky Horror...

Be Just, and Fear Not.

(weakest)
 
Stutter
Once again you fucknut...

I didn't skimp on price I paid 20k for a fully loaded car compact car. 20K is not cheap for a compact car. I could have bought 2 KIAs for the price of a MSP. Mazda skimped on the R&D. The things failing on this car are the stuff thrown on to make it a MSP.

It's known a turbo was thrown on with a stronger clutch and LSD to transfer the added power. If the TSF LSD can't hold up to the hp output of a stock MSP, it's a weak pos and is the wrong application for the MSP. If you want to argue the point not if you abuse it...How is using your 170 hp abuse? If it wasn't made to use the power why make it 170 hp in the first place? You want to state it was a batch of bad lsds. Could be but we dont know till more fail and more people b**** ABOUT IT.

Since you are the magazine reading racing expert you know this:
For DRAG - locking spool, you want no slippage to either wheel but even distribution of power.
In auto x, road race or even street you want a LSD that will adjust the best to changing conditions and be reliable. Gear based ATB no clutches or plates to wear or adjusting to a set lock up %.

You like payless shoes, I like nikes. I stand behind the MSP LSD sucks and the quaife is a better built one.

The tri point motors are built to withstand hard racing. W/o spending lots of money it would not be competitive. The money spent is to make it last in a race and fix the flaws in the original design while making it competitive. If you try to race a stock Protege you'll lose horribly.

Give it up, you have an issue with MSP owners and the MSP in general. You claimed your MP3 makes better power than a MSP, why dont you show us your dyno curve?
You would also think nothing of the MSP b/c your MP3 is faster, makes more power, and/or performs better.

Maybe if you quit pushing your ideas onto other MSP drivers you would think that MSP owners are not high on their own pedestal. I have read other posts by you in other threads and you often claim your way.


And to the fucktard above Bloodfeud -
We already went through this arguement on how people treat their car.

You want higher quality?
You want no questions come warranty time?

Then step up and spend some real money. Like at least 50-60k$

Pick up a Boxster S, or a Corvette Z06, or a BMW M3.

It'll drive better, and, the dealer will be much nicer.

Oh no wait... you can't... cause you a broke a$$ M'r F'er.
Buying a more expensive car does not mean you get better service or nicer service people.
Lexus gives someone I know s*** for his IS 300 b/c he added stuff to it like a stereo and wheels. Lexus is not considered cheap either. It's the fact dealers are not aftermarket friendly b/c they are jackasses and ignorant about what part does what and assume when people do mods to their car they abuse it. So quit pulling the abuse flag out of your ass on everyone. Yes, I agree there are some bulls*** claims but like you said, but the dealer is gettin paid for it so why treat people like s***? I know you're talking about people overboosting and blowing motors but this is a LSD failure at stock output in my case. Many dealers often like to pull bulls*** excuses b/c they think their customers know nothing about cars.

Keep in mind you will destroy a million dollar car by driving it improperly.
Please do tell me if I ever go and buy a viper, how am I supposed to properly use the 500 hp. If I cant use a car built to go fast, what good is it for then?

So in this case with the MSP, if I can't use the stuff on the MSP (turbo, LSD, suspension, stereo) why did I buy this car in the first place? I agree hard driving constantly puts more wear and tear on your car's parts, but so does driving in general. This is still not a legit reason to not honor a warranty b/c it's not proof of abuse. The term abuse is very vague and is not defined. Stop and go driving is abuse on the car and so is revving the snot out of it. I heard a dealer pull the excuse you're not supposed to revv your engine above 5000 RPM. I told him why is the redline at 6500 then. The engine is designed to rev up to a certain point, if it can't withstand it periodically, its a weak engine design and the car designers should lower the redline.

And back to the facts. The LSDs that have failed broke in the same place each time. We already know reinforcing the part with TIG welds will make it stronger but it still does not outrule it's a weak bad unit from the factory and the welds could hinder the performance adding unbalanced weight to the drive gear.
If it was already stout we wouldn't have these failures. The 7 known listed cars do not include any other non member cars or members who do not frequent this forum regularly. I am sure there are others as T3ase has already mentioned another in one of his posts.

If you dont like or want to believe the rants on how stuff on the car is crappy dont read it, or face the reality that it is. If you think by letting people know the problems lowers your car value. Tough s***, you made the mistake thinking a vehicle purchase is good return investment.

How did the welding went? Can you take some pics how it was done and where excactly?

Also if there is anyone who has installed quaife, what modifications you need to do the the tranny for it to fit in?
