Default Review of the MFactory Sport Axles - 06-01-2016, 11:54 AM

For the past couple of months, I have been running the MFactory Sport Axles and wanted to share my experiences with them.

From the moment I opened the boxes, I knew these were going to be much more robust that the stockers. I have added a couple pics for comparison to the stock ones on my 135i. (My greasy hands dont take great pictures )

The shafts themselves are a bit thinner compared to stock but they felt to be around the same weight (with my super scientific test of holding one in each hand). Believe me when I tell you though these things are definitely more robust in every way. Out of curiosity, I opened up the boot to check out the joints which I unfortunately don't have a picture of. The ball bearings and machining inside were impeccable right in line with all of MFactory's products.

Install was a breeze with having both stock axles out in about 30 mins and the new ones in within another 45 mins torqued and ready to go. (FYI did this on the ground with a single jack and 1 jack stand to modulate the rear control arm)

Just as a word of advice, these things are machined perfectly to the point where you cant just slide/bang them through the hub. Luckily, I have a friend that works at a BMW dealer and was able to bring their axle tool which catches on the threads on the outside of the hub and pulls the axle through. I also recommend buying new lock nuts as well as they are crimped/dented in on the end to prevent them from backing off from the factory.

Similar to this. https://www.fcpeuro.com/products/bmw...qi0aAn8R8P8HAQ

From the first drive until now, I could not tell a single difference in driveability. If someone had swapped them overnight without me knowing, I would be clueless. Not a single noice, vibration, nothing.

In terms of strength, I have launched my car from a dig numerous times and i have run upwards of 30psi on my single turbo banging through the gears with absolutely no issues. I have not dynoed my car yet but in terms of wheel torque, I have seen similar setups making anywhere from 600-650wtq so I would estimate I am currently in that area.

I have these axles paired with my MFactory LSD which I also love almost as much as my single turbo kit.

For the money, you honestly cannot go wrong with these axles. No worry of sending cores in to have rebuilt with stock CV joints, amazing quality, and the lifetime warranty, don't even think twice about buying these!

How do you figure they are more robust in every way? What qualifications and testing do you have to make that statement?

Often times aftermarket companies (with the exceptions of established ones like DSS) have a tough time making a stronger axle/shafts because they simply can not source as good of materials as OEM

Thanks for the review, much appreciated

For those wondering why our centre shafts are thinner than stock, it is for one reason: weight savings, which helps tremendously with rotational mass. Even though our shafts are slightly thinner than stock, they are made from Forged SAE9310, so the tensile strength, torsional resistance and elasticity far exceeds the oem shafts.

Not that that matters though, as the centre portion of the shaft is not the weak point on axles; the weak points are the outer ends of the centre shaft (notice how the oem shaft tapers inwards at the ends. In comparison, ours taper outwards at the ends), and of course the splines on the CV joints, with our CV joints also being made from Forged SAE9310, with rolled splines.

OEM use a medium carbon steel for their shafts.

Our shafts are Forged from SAE9310 steel. Sourcing better materials than oem is not hard at all.

Seeing as though you have an XI, are on stock turbos, and have probably never dragged raced your car, I can see why you are skeptical by me calling them more robust.

I have dealt with BMWs for a long time and have seen/broken my own axles before leading me to look for an upgraded set. If you were to handle them yourself, you would see that the CV joint has no slop in it whatsoever unlike the OEM unit. Although i was considering going with DSS as you mentioned, they required me to send in my specific axles as they had never done 135 axles before. Obviously time is the ultimate test on these but in terms of strength, I can guarantee you I have abused them more than enough to know they are stout!

Reviewing an axle is kind of pointless. It is like review a bolt. If it holds, it holds...

And if we didn't have independent reviews, how would we let our potential customers know about our product? Yes, of course, we will have them advertised on our own threads, but guess what the 1st question that always pops up is? Yup, you guessed it: "are there any reviews"

What are the reasons to buy these over the DSS axles? Just curious how yours compare because they are the same price once you are done with the discounted ones.

-$999
-inner CV and outer CV internal upgrade, using our 36 spline high grade aircraft quality
-custom chromoly CV cage and race set
-Chromoly 108mm inner CV (full aerospace grade internals)
-Upgraded stock outer CV with aerospace grade internals

The main difference is that ours is a complete kit that is direct swap of your oem axles, with all of our parts upgraded, including the whole CV joint

With theirs, you have to send in your oem axles, then wait 2 weeks while they "upgrade" your oem axles, and you still end up only having oem CV joints (albeit with upgraded internals)

The reason why they do this is because of the costs involved to develop a whole new CV Joint (inner & outer) for the BMW, which is completely different from most other setups which are simple (i.e generic, one-size-fits-many) in comparison.

Well, your posts are a lot more helpful than OP's "review" Specs talk for these kind of things. We are not buying a mattress here, no need for "review" lol

I apologize I don't know specifics as I did not engineer nor manufactor the product which is why MFactory is chiming in for that info. I merely felt I would share my opinion and results as MOST people would like info from fellow members on the forum and not just what the company states.

I appreciate the review Boston! I actually must of missed this option and look forward to seeing how you and Terry put them through the ringer. I have a feeling I will be ordering a set of these sooner vs later.

No problem brother! Im sure if I didnt put them through their full paces, Terry will haha. Ive been looking to get an upgraded set of axles forever but didn't want to send mine in. Glad I waited!

Do these come with stronger bolts or did you use oem?

Also, to mfactory.... I would like to add my input that we need a carbon fiber driveshaft for this platform. Would you please start looking into this...

The problem is that the driveshaft itself isn't what usually breaks for us, it's the spline connection to the diff that shears / breaks.


Enjoying the new tables discovered and the XDF progress made? if you'd like. Every bit is appreciated!

Glad you asked. We are actually testing our new Carbon Propshaft as we speak. More details shortly

Getting the weights just now. Will update shortly. With regards to the F20/30, I will need to do some research on the axle fitments for those. The diffs themselves are the same, so just a matter of axle length

Thanks for your feedback. So upgraded axle stubs you say? hmm...should be simple enough to make
