For all of you with LSD breakage problems...

[therieldeal]

There is now a permanent, awesome, and affordable solution!

I just finally finished up running a group buy with MFactory, designing helical LSD's similar to the Quaife at a much more affordable price. For the record - I don't work for them.. I'm just really excited about these things, and hopefully you will be too. There was such a large response to the group buy (nearly 50 people) that they have decided to carry these LSD's on their website from now on:

http://www.teammfactory.com/products.php?category=Helical LSD&mod=MZ

The retail price is $669.95 plus shipping, and the special ring gear bolts needed are included, unlike the Quaife. We also worked out a different design for the bolts, so no grinding to the shift gate will be required. It will be a 100% drop-in installation.

Testing has been done in both a road race car and a 10 second ford probe... so rest assured, this thing isn't going to let go on you. If you're still concerned, check out reviews of their products over at honda-tech.

Just an FYI for all of you guys . Here are some pics:

One of the sample diffs the day it arrived at my place of work back in January.

One of the special bolts - M10 left-hand thread like a honda ring gear bolt, but shouldered to fit the ~11.2mm (going from memory here) hole in the g-series ring gear. The flange of the differential has threaded holes, so there are no nuts required.

Lots of questions were asked and answered in the original group buy thread:

However, if you have any questions about these things feel free to ask me.

mmmm ive been watching these on CP. are they finally done?

 

[therieldeal]

yessir, they finished the batch for the group buy this past week.

i'm assuming they also made extras for stock, as they are now listed as "in stock" on their website. just a few days ago they were listed as back-ordered.

 

[SCMP3]

how long will they be making them? i dont have the moneys right now.

 

[therieldeal]

there is no timeframe, they are making these part of their product line. spread the word!

 

[SCMP3]

ok cool

 

[Dpwhitehead1]

that's awesome.. but WHY is it so cheap?? that's weird... especially if they're BETTER...

this is for the msp correct?

 

[therieldeal]

yes the 28 spline version will fit the MSP

i dont work there so i cant tell you specifically why the are so much less than a quaife... but if i had to guess i'd say it has a lot to do with where they are made (hong kong vs. U.K.) and how much they are being marked up. when you buy a quaife a lot of the money you spend is for the name.

i can assure you that these are very high quality parts... i test fitted the original prototypes myself, and the fit was flawless. i know some people may be skeptical because this is a new product for us mazda guys... but they have been making honda parts for a couple years now. check out the reviews...

ok. one last question since you've seen it etc.. what kinda warranty is on this?

 

[Outlawstar98]

Lol i got my welded LSD for 600$, and it wont break even if its a 10 second car. so to me, no point on me getting it since I have a welded LSD.

[Dpwhitehead1]

thanks. i'll be getting one of these.. sick and tired of seeing quaifes going for 1300.00 plus.. thanks a ton for this option.

i'm not so sure about that... the stock MSP lsd's are not too far off from the standard open diff. 2 spider diffs simply are not very strong... once you solve the problem of the housing breaking, at some point you will run into this problem:

that took only 10k miles at 275hp or less. stripped half the teeth off of the spider gears. yes i know its an open diff, but i like i said the MSP LSD is basically just an open diff with some small clutch packs between the side gears and the housing.

 

[Outlawstar98]

Explain to me why mazdaspeed20035 had over 500HP on his car for well over a year, and still has the stock LSD, but has it welded.

And that's not even a MSP LSD in that pic you posted. I have NEVER seen a LSD in a MSP look like that, NEVER.

The weakpoint in the MSP LSD is that the casein falls off, which why we get it welded.

 

[dandan2]

but u just spend the same amount of money on a factory part that u better have alot of faith in those welds because u could of gotton a much finer product as shown here on this thread~!

 

[Outlawstar98]

The factory LSD welded is a fine product though, im not saying dont get it, but im saying that you cant justify getting this one over a Welded Factory LSD cause its "better" when the factory LSD can easily hold whatever most people though at it.

Edit: You dont spend the same amount 600$ for a welded LSD factory one for me, this one is 700$. Im just correcting what you said that is all. To me 100$ ATM is alot, cause of darn bills

Alright enough of the stupid talk. People pay 1300 already for the Quaife. There are obviously people that want this product and now that a company comes along and produces what seems to be a quality product at a very good price, people decide to crop up and say "oh it's unnecessary". Let's not become like a majority of the SRT-4 crowd or worse.

On the other hand, due to this being a new product that is offered to the public, there is question whether you will need AV status. The mods are reviewing it right now. It's only for the safety of the community. We'll let you know what the decision is (thumb)

 

[Shadow102]

The point of these I would think is not to aleviate the breakage problem as we have already discovered a solution for that problem. This is more for people who a. Already broke their diff and need a replacement or b. Want a better style diff as opposed to the msp diff

 

[43975]

Why would he need AV status?? Isn't he just notifying us of a new product for our cars??? I could see if he worked for them...

 

[therieldeal]

yeah i'm not sure why i would need AV status either... i'm not selling anything, just letting you guys know that the group buy is successfully over and the product is on their shelf. if i came on here and posted "hey look corksport has a new FMIC kit" would i need AV status?

i know that isnt an MSP lsd that i posted a picture of, i thought i was pretty clear on the fact that i was posting a picture of my escort's stock open diff. regardless of how you feel about it, a g-series open diff is not far off from the MSP LSD.

either way, it doesnt matter... a helical LSD has lots of other performance qualities that make it much better than the stock LSD... think what you want though. it's not entirely about whether or not it will "hold up to xxx hp".
