George sure knows his stuff. Love listening to these tech talks. The M4 has seen some serious action, only fair that it receives a full refresh. The Kubica lap alone was something to behold.

[@shiftdnb]

These type of episodes are some of my favorite trying to take over a lot of the maintenance myself in my car. The M2 one they did is one of my favorite.

[@Chicomacheeno]

He rented that car for the week. George was impressed with how many parts he needed to replace after. lol

[@dinosoarskill17]

Previous owner of my M4 installed a Turner Motorsport skid plate under that oil cooler, and man it saved me from some serious damage

[@FullgasNoTraction]

I love these workshop vids and it looks like your cameraman is back Misha!

[@mgcharoudin]

This is something we filmed back when he was here, but I gave him the priority of editing the other videos first. The main of which will be published on the 26th (available in members section already).

[@iiNNeX]

From my understanding the latest iStep updates to the F8x platform do sort out the mapping, it is worth getting all the modules changed. There is a huge discussion on it on bimmerpost and people have reported great results. It does exactly as you said, moves the torque curve up and makes it more linear (almost makes the car feel NA like in power delivery). It has improvements on Diff and Gearbox behaviour too. My F82 CP is going in for this soon.

[@anetaflisik-majewska1576]

Like Aircraft standards. Bravo. I will like to see my self in this dream team.

[@shiftdnb]

Love these interviews with George and getting the info on the cars and the issues that arise, what to look out for and how to handle them when tracking a car.

[@Emil_Bucholc]

Cool video 👍🏻

[@TheMx5Channel]

15:35 it's true, just like black can absorb light (heat) it also means it can radiate heat the same way. The reason why some space parts are black is to radiate heat better. White can reflect alot but when hot it takes more time to lose it's heat. Not sure how much it will help. Can be as little as a few degrees but when pushing 300/400 degrees it might be a way to keep the brakes cooler ;)

[@martinchapman2168]

Good video

An "Apex Garage" sounds like a great idea! ~ Apex Tuning & Consulting Nordschleife, 1,000,000 km+ of Ring experience .

Nice to see some real world figures/experiences from people who run stuff hard and not all the stuff many UK, US and Japanese tuning companies sell and claim you need to be fast.

[@user-ds9fr5bj9s]

Love this kind of videos. It would be great to see one where you talk us through suspension mods- kinematic kits, diff mounts and how it affects the handling, how alignment setup can influence the car behaviour etc. BTW, what’s with the e36 racecar project? That would be also cool to compare its chassis with an ordinary e36.

[@portalracingcanarias6608]

[@oem_marek1192]

Gr8 Video to see the background of techs and the workshop routine! Just to clarify, I guess you guys are running a crank hub fix. Maybe a primary cat delete would be a good thing to do, just for durability and heat reasons, as well as drop in filters and air scoops, as the stock air boxes are already good to go :)

[@tobywonkinoby8916]

Oh yes, this tech stuff is TASTY!!! Can't wait for more build videos. Note for the editor: excessive contrast seems a little bit distracting, I also suggest to check your colour temperature looking at the skin tones, you don't want to make people looking like zombies ;) Loved smooth camera motion though, keep it up!

[@thomasbryce7151]

Morning MiSHA & George.. By Crikey you know your stuff George! Even I was surprised how much stress & strain a cars suspension takes under load in racing conditions.. (15Tons !! 😲) If I was living in Nurburgring & you operated your own Garage I'd be a regular loyal customer & have my vehicle's serviced by you..👍🙂👍 Not long to go & th'Ring will be open for business again Great ! definitely looking forward to seeing the new & improved Video productions you have in store for us Misha Love Ya Work bro 💕 Godbless ava G'day 🙂

[@DuBstep115]

[@dinosoarskill17]

[@jonathanblease244]

I love these type of videos, it’s great to here from REAL WORLD experience. I have an M2 Comp which as you know is basically the same platform, I did 18 UK Trackdays last year (about 10k miles), lots of mods (kinematics, suspension) but like you guys run stock power and brakes. Great to hear your feedback on brakes, I’ve had the same experience despite most people on forums saying they must be changed! Il be leaving them as is. Ps are those rear lights non LCI!?

[@hovnojede010101]

Girodisc rotors for the stock blue or 2NH brakes are a great upgrade. I'm far from fast, but they've made a noticeable difference still, in conjunction with proper pads.

[@FreestylerAlbert]

In the biginning I was worried the intercooler wanted to be painted black :D Because that's actually worse heat dissipation wise. :)

[@alexoehler1]

As an M4 owner I'd be interested in more details about the dct service. Do you change the plastic pan every time? How/ How much do you overfill the box the first time before running the gears (how much time?) ?

[@romanjacobs1794]

He said in this video, that he changes plastic pan every second oil change.

[@Mr1994Tanja]

I would love to have Apex build my E90 M3.

[@Andy-iw4xu]

I would love to see a similar video on your m2c. I’m interested in seeing the wear and tear on a car where all the suspension has been changed removing the rubber.

[@mgcharoudin]

Unfortunately M2 is gone

[@cutdepiefails6596]

The m2c is fairly similar. I wouldn't be surprised the 'problems' would be similar if not the same.

[@yakev724]

Good video, love the technicals w George. Curious to hear his impression of N55 vs S55. By that token sounds like M2 is more appealing all around as a platform? Takes the same suspension with slightly lower weight? Or due to it fitting narrower tires prefer the F80/82?

[@carlparker1995]

don't think it was mentioned in the video but what kw's are you changing too? what brake pads are you guys running? once again another great video, love the technical videos with george in, great work guys.

[@tomasis7]

id love to see a video about nurburgring setup for E9x. Im in process to change to new bushings. I didnt decide what. PU? Sherman is nice but too extreme etc. Id love to see you speak about what is best for E9x daily driver and nurburgring setup. :)

[@goaski474]

Awesome as usual! What are the normal annual running expenses, excluding accidents?

[@MihaiRece]

[@mgcharoudin]

Yep

[@8359s]

Could you show some tips regarding setting up suspension geometry?

[@davidfreeman4407]

Garage Whifbitz do a lot of work with most m cars the may have a solution to the oil cooler issue.

[@MatthewM770]

So will you have it where someone could send you their F80 for example. With a menu list of upgrades/replacements?

[@tigeralpha1480]

Is the crankhub stock on the m3/m4?

[@mkm6073]

Very interesting changes you're planning! Planning on building a G87 tool when it comes out, hope you'll be ahead of me with that, so I can get some more insights what's working etc!;) Is there a specific reason, why you are using this strange filters on the filming now? Looks not so natural I have to say:/

[@JamesCairney]

These videos are good, and you could go into more detail 'cause we're car geeks and that, know?

[@RDSAlphard]

I love this, I'm surprised by how many stuff need to change in a year... but then, this car is abused to hell & back on Green Hell.

[@derbigpr500]

Not much of that has to be changed, it's mostly preventative. The car would probably run fine for another year without most of these replacements not done now.

[@romanjacobs1794]

Misha, where do u do wheel alignment?

[@tunerzvnz]

do you use oil trap door pan baffle kit in any of the cars? like the cupra for example?

[@mgcharoudin]

Nope, all stock

[@FireEye-zd4fm]

Jean-Pierre from Motoren Zimmer mentioned on one of the "Nordschleife GTR" videos (IIRC) that the wear on track is up to ten times as much as on the public road, would you agree ?

[@vollcare4076]

That’s the general rule of thumb since decades

[@brandonn50233]

Pretty surprised that you aren’t running something like the Turner oil cooler skid plate that’s metal instead of the factory plastic. Glad to see the stock plate has survived the beating. Just curious, do you only run the crank bolt capture or have you installed an aftermarket crankhub ? My apologies if I’m beating a dead horse on that question

[@mgcharoudin]

It is indeed a dead horse. It's a typical US thing for people who run ridiculous power and do street drag pulls. Then it may be necessary. In our case no problem

[@Chicomacheeno]

Does anyone else hear an echo in this video? I realize it’s a large open space but just wondering if a directional microphone would improve the audio.

[@stuurmeemail]

Do you ever check the wear of the engine? If yes: how? Are the horses still there?

[@omarg6022]

The black calipers/black painted anything isn't true. Engineering explained did a video on it too if you don't believe me but basically black seems to dissipate heat because it absorbs light which then turns into heat but black does not absorb heat. Adding any color layer of paint is paint and it actually makes it harder for the item to dissipate heat because it acts as a layer of insulation. The logic came from how black surfaces get hotter than a white surfaces so it can cool more heat but it does not help with heat dissipation. Just anodize you calipers if there aluminum.

[@Lucas-ij6kk]

stock crankhub on motor?

[@adamfreeman3000]

What brake pads are you running guys? Just curious because you say the OEM discs last forever, yet pretty much everyone is struggling with brake judder on M4’s once they get even a little bit of heat in them. Everyone seems to be replacing discs like crazy but perhaps it’s the pad your using?

[@mixworks-de]

Looks like Endless pads to me (blue)

[@garagecedric]

Endless are of course great pads, but the ring is super easy on brakes compared to smaller tracks.

[@David-uq4ns]

@@vollcare4076 when it comes to the nordschleife you dont want your suspension to be very stiff like on gp tracks, tho im not no expert so just use whatever u feel fits your car the best

[@vollcare4076]

@@David-uq4ns In general you are right: you do not need that stiff suspension on NOS as if you would drive on a GPT track. but even this club sport V3 will be too soft for a car that will be used not as a daily anymore and only for track use. V3 Clubsport is a good suspension if you use your car as a compromise daily & track. But this has pretty soft spring rates: E.g. Only 70N/mm one front spring where the JRZ suspension has 140N/mm as i can see. So in case you’ll really install the V3 Clubsport I expect that you’d like to change the spring rate at least to sth about 100 or 120 on front

The new videography is appreciated but you'll need better lighting. I'd suggest laying a few LED shop lights on the floor temporarily while you film the undersides of cars on the lift. Your camera needs a flood light and George needs a spot flashlight/torch and a green laser pointer. We also need at least one close shot of Pancake looking into the camera in each video. Put a piece of chicken on top of the camera/phone and when she see's it, drop it on the floor for her to eat. Do this enough times so she becomes used to checking the camera for random treats. Sorry Misha, Pancake is "easier on the eyes" than you.
