MFactory LSD 750$!!!

***I need everyone who is a committed buyer to check the list and make sure that*** >>>


1) you are on the list and,
2) your specific order is known and listed, so post your order if it's not on the list e.g. "Auto/Manual, Bolted/Welded, LSD/Pumpkin". AND:
3)
ALSO list any extra things that you want (to buy), such as a gear ratio change (i.e. 3.08 to 3.46 - 300$), anything want from their website along with the order...

*** please read all the way thru before asking questions thank you ***

What it boils down to:

$1274 for bolted
$1699 for wlded


----------------------
All the BMW helical LSD’s are $800 @ 10 or more units sold (20% OFF!!)

If we buy 20 or more units it will cost $750 @ 25% OFF!!!

if you have a bolted diff then this can be a great option for you, as it can be bolted into your current diff, if you have a welded diff, like myself, a good option would be to buy a fully built unit (pumpkin), and send back your core (old diff) as the installation of the LSD unit is a not a DIY process, therefore would require LOTS of downtime and confusion...

for welded diff people, we have the option of purchasing in entire fully built LSD pumpkin and send back the core for a refund, the core refund is 500$, which is payed upfront along with the price of the fully built pumpkin...
Fully built pumpkins will be discounted @ 15% when we reach 10+ units
E.g. $1999 LSD fully built for $1699 after core refund of 500$

if anyone if looking to change the gear ratio it is an extra 300$ i.e 3.08 to 3.46:1

The fully built diffs have the Backlash and wear pattern, as well as the preload set

the cores would need to be shipped back to them in California

you can check their website for any info they have listed: (the price difference is based on welded or bolted as welded requires machining)
http://www.synchrotech-transmissions.com/

Once the orders are payed for and shipping is payed for we will add all the LSD’s to our stock order. Those usually take about 4-6 weeks to get to us and then we will ship them to the customers from here.

The gear ratio depends on what unit you are working with. They will not offer any custom gearing in the group buy

Post here if you are interested and or committed buyers, as soon as we have committed buyers posted we can get the diffs!!! Have money ready before committing to purchase please...

Post any and all questions to me (Cameron ShineandRecline Padron on FB) or here if they apply to the group....

subbed.... few questions....

how long will it take for the order to be filled? this gb already took a month to start....

where does the core have to be shipped and how long do we have to return the core?

is the full pumpkin rebuilt with new seals and shimmed to correct gear lash?

are the full pumpkins welded or bolted?

any difference in price for small and big pumpkins?

choice of gear ratios and $$?

any extra options that sounds racecar and cost a bunch but we will never notice the difference?

thanks

I'm getting all those questions answered for you, IIRC the gears are all the same price tho, not sure about the size, and or what you mean by that? What kind of diff do you have on the car now? And what do you want?

It's my job to field any and all questions for you guys so ask away... I know y'all need an LSD!! What good is all that boost and tuning if you can't put it to the road? So let's get some buyers lined up... I only started with welded fully built prices because that is what the majority of people initially interested wanted / needed, but I'll have more details at the open of pacific coast business time tomorrow... cheers!

$1699 for welded and $1274 for bolted at 10+ after core refund ($500)
It is 15% on full pumpkins and 25% on just the LSD unit... which kinda makes sense but is not how we originally understood it...
http://shop.synchrotech-transmissions.com/BMW_c53.htm
And yes 800 and 750 at 10 or 20+... I'll get some shipping prices, but I'm sure you could find that on the website, I'll see if they will do the discount for shipping also if possible

So if we buy the fully built bolted pumpkin (i would need small bolted pumpkin, at), its remove old open diff and pop in LSD?

If not, we would have to open up old diff, remove internals, replace internals, check backlash, etc.

I'm in for the bolted full pumpkin 3.46 AT. We receive the whole pumpkin with the LSD in it and send our stock pumpkin in, correct?

"$1200 Bolted + core"

Small pumpkin, AT?

I was wrong, the correct price is:
$1699 for welded and $1274 for bolted at 10+ after core refund ($500)
It is 15% on full pumpkins and 25% on just the LSD unit... which kinda makes sense but is not how we originally understood it...
http://shop.synchrotech-transmissions.com/BMW_c53.htm
And yes 800 and 750 at 10 or 20+... I'll get some shipping prices, but I'm sure you could find that on the website, I'll see if they will do the discount for shipping also if possible

So Prices:

$1274 Bolted + core
$1699 Welded + core

Or $800 LSD only. All prices are @ 10 units

Are they doing any deals with the full pumpkin + install at their facility?
I'm not too far from them so if they do installs I could also avoid the core exchange.
