E46 M3 diff GEAR RATIO CHANGE | 4.10 gears installation tutorial

#E46M3 #GearRatio #CWP #4.10
In this video we show you how to swap 4.10:1 Gear ratio into your E46 M3. This tutorial is applicable to ALL M models as the concept is the same.
This is considered as the most popular upgrade for track enthusiasts, so we consider this knowledge very valuable.
Besides gear ratio change, we also recommend clutch replacement. We also did a couple of videos about that which you can check on following links:
• BMW E46 M3 LSD mechani...
• BMW M Variable V2 LSD ...
• BMW E46 M3 Differentia...
You can purchase all used parts and tools on our web shop and get them delivered to your garage door.

Really helpful video the music was a little loud and distracting but overall pretty good video:)

[@BMWarrior1]

amazing knowledge and understanding - true expert in their field. Keep up the great work guys!

[@RacingDiffs]

Thank you👍🏻

[@PRAGEETHKARUNADHEERA]

Very well explained. Easty to understand. Enjoyed watching this.

[@RacingDiffs]

I'm glad to hear that! Thank you for the feedback 👍🏻

[@scipperdsbc9521]

Perfekt 👌

[@georgekrapivko7663]

Love mine!

[@Oxigan2win]

Hello - tightening the pinion - is it the same procedure for the 188K 330 CI E46 3.93 diff? Thanks and very very nice video!

[@RacingDiffs]

Yes, pretty much the same👍🏻

[@lukathegarlic]

In one of your E46 M3 videos you said the pinion bearing preload should be 0,6Nm to 0,8Nm. In this video you state 0,8Nm to 1Nm. Why is there a difference now, is this specific for each differential type or is it based on bearing sizing? Also the backlash was said in one of the previous videos to be between 0,05mm - 0,08mm. Now it is 0,1mm to 0,12mm. I hope you can respond, I would like to understand the difference. Why don't you provide crush sleeve anymore but the shim instead? It is a much better solution to put a new crush sleeve in and the cost difference should be negligible. Thanks!

[@albobaggins5557]

I had the exact same questions, the torque spec on the crown wheel bolts changes also

[@onesikm3]

Great video but I noticed improper use of thread locker! In a blind hose you should always put thread locker inside the hole first then when you drive the bolt in it will actually do what it’s supposed to 😄

Jak można mierzyć ustawienie łożysk jeśli wymieniono tylko jedno łożysko? Przy kosztach zakupu nowego zestawu kół zębatych to żadna oszczędność pieniędzy. Należy wymienić oba łożyska i dokonać pomiaru i regulacji napięcia. A gdzie pomiar głębokości osadzenia walka ataku? Obawiam się że jest to o wiele trudniejsze jak przedstawia ten film.

hi guys, i have a question, i have a bmw e39 520i from 96' that has a M52B20 engine, after i did some research i found out that i have a 188k type diff, id like to purchase a LSD set that you guys offer, but im curious to know if i need to grind the spider gears too

[@RacingDiffs]

The new version doesn't requre grinding ovlf spider gears. You can see full installation video right here. kzbin.info/www/bejne/mH2ohJmelqiFhac

[@doomslayer5044]

@@RacingDiffs thank you so much for the fast answer, cant wait to order a set

[@sandpiper1515]

For your LSD conversion kits how robust are they? Could they be use for "Racing" as the name implies?

[@TGLasers]

If you are anything serious about racing get a propper LSD core from them...

[@RacingDiffs]

They are designed for street usage. RacingDiffs is name of the brand, product is LSD conversion kit. 🙂

[@jacklay6867]

Mr. May I have a question for you, how much oil to put in the Differential?

[@RacingDiffs]

Put the diff on a flat surface, like on the car. Fill in the oil until it starts to leak from the upper oil plug. Close the plug. For E46 M3 diff, you will need about 1.8L of oil.

[@7H3_23R0]

Could you please tell me what is your shoes's brand?

[@RacingDiffs]

Skechers 😊

[@coreytelfer4566]

What is the torque wrench used in this video?

[@RacingDiffs]

We got good old wrench, which we calibrated and it works perfect. But don't know the make. I'm sure similars are to be found on Ebay.

[@johnyxxx]

Love your video's, but please stop using that background music when he is talking, it's very annoying. Thanks!

[@RacingDiffs]

Thanks for feedback 👍🏻

[@eXoguti094]

God the music is so loud... You guys don't need any music in these videos, we're just interested in the straight-up talking

[@1Heyfred]

Good video, but the music is annoying and makes it hard to follow.

[@RacingDiffs]

Appreciate the feedback. 👍🏻
