Hey guys,

just registered as a sponsor, and we are looking for testers for the new MFactory C63 AMG Helical LSD (as used on our very own Project C63 AMG: https://mbworld.org/forums/c63-amg-w...t-c63-amg.html ):



Gain a prominent advantage over the competition with the MFactory Helical Limited Slip Differential. Through the smooth and constant distribution of power to the wheels, the MFactory Helical LSD puts the power-to-the-ground and maximises your vehicle's traction. A must for any race car, be it Street, Strip or Track!

Diamond Cut to exacting tolerances from Forged High-Nickel-Chromium-Molybdenum Steel
Perfect fitment & finish ensures hassle-free installation & maintenance, each and every time

Designed using leading-edge Solidworks 3D CAD & Cosmos FEA software
Advanced Gear Geometry minimizes parasitic drivetrain losses. Race transmissions built with MFactory components transfer, on average, 1-2% more power to the ground over our competitors!

2nd Generation Design
The MFactory v2 Helical LSD is lighter, stronger and more efficient than any other Torque-Biasing Differential on the market today!

Covered by the MFactory Lifetime, Globally Transferable Warranty
Whether used on the Street, Strip or Track, all MFactory Helical LSD's come with a Lifetime, No-Hassle, Globally Transferable Warranty

No-Load/One-Wheel Syndrome
A common misconception is that a Torsen-Style Differential is useless under a no-load situation (e.g One wheel in the air). Although true to an extent, this no-load situation does not apply to the modern day car with Traction Control (or eDiff). For those without traction control, there is a very commonly used solution to the problem (used by professional race car drivers over the past 30+ years) that our competitors will not tell you; simply left-foot brake

Specifications:

• Made from imported Japanese SAE 4320 & SAE 9310 Steel
• Forged, Double Tempered and Super Sub-Zero treated for unsurpassed toughness
• Advanced Shot Peening technology increases surface hardness
• Designed to withstand the extreme shock loads of competition-level Drag Racing
• Advanced gear geometry designed using industry-leading software puts more power to the ground
• Only the highest quality Brighton-Best Hardware is used
• Maintenance-free Gears eliminates the need for special fluids & rebuilds associated with plate-type LSDs
• Lock-free operation ensures no adverse affect to steering response

Pricing:
LSD Only: MSRP - $999.95. Forum Price - $799.95 + Shipping

Differential Rebuild Service (with Helical LSD):

• For the utmost in convenience, we offer a core exchange program whereby customers have up to 30 days from receipt of their pre-built carrier to return their old core to us for a $500 refund

• All internal parts are checked for wear, cleaned in our steam washer, de-burred then re-assembled within oem specifications

• All core housings are cleaned, sand-blasted and repainted, leaving our facility in "as new" condition

Pricing:
Ship us your core: MSRP $1499.95. Forum Price - $1299.95 + Shipping
Purchase a rebuilt core: MSRP $1999.95 (inc. $500 core fee). Forum Price - $1799.95 (inc. $500 core fee) + Shipping

I'm not in the market for an LSD, but the picture shows bearings. Are they included? Are any seals or fluid included? $800 seems like a pretty good deal for those looking for a diff. It will be interesting to see what feedback people have for this diff compared to the Quaife and Wavetrac.

SaphGreyC63

Couple questions.

1) where are you guys located?
2) Is the price listed for those you are looking to help test or just a forum special?

CaptnCharisma

Is removing material from the casing required like some other differentials on the market?

Phil Chow

+1 to answers on all the above questions, interesting.

MFactory makes some pretty good stuff.

YCW

When buying just the LSD unit only (i.e to install yourself), bearings/seals/oil are not included, no; it is for just the LSD only. Bearings are shown in the image as we had just removed the LSD from a core we built so that I could take an image for the forum. I will replace with a new image asap.

Everytime we enter a new market/fitment (we are not a new company. We are one of the largest aftermarket LSD manufacturers in the world), we always get asked the question between our competitors (those two) and ours.

Our goal from the beginning when developing our own Helical LSD was to offer a unit that was both metallurgically stronger and more affordable than the competition, as well as performing just as well, if not better.

All MFactory Helical LSD's are:
- Forged SAE4320 Housings (both Quaife and Wavetrac use SAE8620 and are not Forged)
- Forged SAE9310 Internals (Quaife use SAE8620 and Wavetrac use SAE9310. Neither are Forged)
- Increased Bias Ratio (how much torque can be transferred to the wheel with traction) of 75% (Both Quaife and Wavetrac are 66%)
- Globally transferable Lifetime Warranty (should you decide to sell the LSD at a later date, no matter which country, the new owner will still have a Lifetime Warranty)

In addition, we are very well known for both our pre-sale and post-sale customer support (unlike those two).

A quick search on Google will bring up hundreds of results. We are the worlds largest (by far) Honda drivetrain specialist, OEM for both Honda and Toyota, and are one of North America's largest BMW Specialists. Hence, we are now expanding into the Mercedes market.

1) Our R&D Facility is in San Dimas, CA
2) We don't need to test the unit further, as we've already done all the fitment testing on our own project car. We have pre-built cores on-the-shelf ready to ship. The price listed is for forum members. We are looking for cars to sponsor though and help spread the word. Those interested can PM us.

It is not required, no. We specifically designed our LSD around the oem dimensions so that there will not be any clearance issues.

Phil Chow

Forgive me lack of knowledge, but,

Is the MFactory the same "Type" as the Quafie/Peloquins? I know the WaveTracs are slightly "Different", and people seem to think they're better?

YCW

Yes, it is a Torque Biasing differential, as are Wavetrac, Quaife and Peloquin.

Although Wavetrac have their patented wave mechanism, this was not designed by them (it was designed by Quaife, then taken by Autotech/Wavetrac after Autotech stopped becoming Quaife's US Distributor). It was originally designed for 20 year old VW's with no traction control, thus the whole "solves the no-load-one-wheel-in-the-air" issue. However, this no-load situation does not apply to the modern day car with Traction Control (or eDiff) as your traction control (via your rear brakes) serves the same function. This is why Quaife ditched the idea in the first place as it was pointless (unless you were a company that specialises in 20 year old VW's i.e Autotech/Wavetrac) and doesn't really affect 95% of the market. Instead, Quaife done what we done, and developed (well, they bought out another company) a Plate LSD as well for those who really need something that locks. There is no place for a "hybrid", unless you are Autotech looking to tap into the 5% market.

It's all in the marketing

SaphGreyC63

You've got to be kidding me! I grew up in San Dimas. Lived here all my life and still do! I have to stop by!

Would you mind posting address or PM it to me along with your hours?

YCW

haha, coincidence

Our address is:

MFactory R&D
581 W. Covina Blvd

You are more than welcome to come visit at anytime (call and ask for David Henson, the facility manager, and tell him Michael from HQ referred you), and we can take you for a tour around the facility and see how we prepare and rebuild transmissions and cores; we have not once failed to impress our visitors

SaphGreyC63

Great thanks so much. I've been wanting to get an LSD in the car too so this may all work out. I may even stop by tomorrow morning as long as I wake up in time. You guys are 1.5 miles away from my house.

YCW

No worries at all

We have a pumpkin built and on-the-shelf, ready for a core exchange (due to zoning though, we can't actually work directly on cars, so you would need to organise with another garage to remove/install the pumpkin). Or you can purchase the LSD unit only.

Either way though, it would need to be ordered directly through myself on this forum at the moment, as this is still a new part so I'm the only one authorised to offer the forum discounts.

CaptnCharisma

I think this just ended up on my Christmas list. What were you looking for from testers other than just a car to put it on?

YCW

It was actually more sponsored drivers (to help promote our products) than actual testers, as the LSD has already been fully tested with no issues on our own project car.

The Forum pricing above is available to all forum members (whilst stocks last), but if you think you are a suitable candidate for sponsorship, please feel free to PM me

YCW

All PM's replied

YCW

Down to one last core in stock!

YCW

Still have this 1 last core in stock! Get it while you can

chong san

I call for lsd, will it be provided? What is the difference between YCW-AER-C63 and YCW-AER-C63? How much? Can it be shipped to Hong Kong?

Cammer88

They might still have 1 in stock...5 years later
