M3/M4 Brake Retrofit DIY: kzbin.info/www/bejne/j2qYgXaZor6Mqas

[@M3nMe]

At this point you’re basically my dad.

[@kern417]

i'll never leave

[@jamesbaker8516]

Relatable

[@LuisMoreno-rs2qk]

Good info. I’m actually looking into brakes for 17’ 440i. This helps. Still waiting on your beatbox outro to come out as a ringtone

[@brumorabia]

Aeroquip is a must and do not forget about upgrading the oil to some rbf700 or something like that. I've installed Stoptech front rotors on my M240i with original pads and it works great

[@aj2734]

Try castrol srf

[@DoughnutFoundation]

Fantastic video man! Wow, this popped up on my feed at a very convenient time, I’m just starting to hear squeals due to thin pads. Time for an upgrade!

[@andreagate542]

Great break down man🎉… so if I’m understanding you correctly, the only difference between the 340 callipers, m performance and the M3 callipers is the mounting bracket depth with no increase in performance in piston size. Many Thxs I will email you for pricing 🙏🏾

[@henhudwrestler]

i have a 2012 bmw 328i and i already have a few upgrades. 1st i have drilled rotors and 2nd i have M edition wheels. can i buy a set of m4 blue brake calipers and put them on ?

[@lamakicker69]

Drilled/Slotted rotors doesn’t really increase performance, its just cosmetic to make the breaks look cooler. Seen people also say that Ferrari and Porsche have actually admitted this, just for looks. It’s why F1 cars don’t have slotted/drilled rotors.

[@kern417]

Ok. Pretty much just repeating what I already said.

[@Sqwin_n20]

The rear rotor depends on what size rear parking brake you have to work with the rear rotor. If you have the ID 16.5 rotor, the rear brackets don’t work. The ID 18 works and is on ~90% of F chassis cars

[@cleotusclump1007]

Thanks!

[@kern417]

thank you so much

[@GoncaloSaSilva]

Great video! The only thing missing was to know if it is possible to run the M3/M4 CCB brakes on our cars.

[@kern417]

theoretically it would mount with my brackets since the adapters replicate the M3 hubs. But i don't have any customers that have tried it yet.

[@nathanb5840]

I wold like to order a set I want to run the m3 rotors all around is the a video for the rear and what you have to take off? Also, I’ve been following forever. Love you at work thank you for your contributions

[@michaelcodreanu790]

Can I use 370mm rotors instead of 340mm ?

[@miggy2225]

When will you make the best BMW B58 platform video?? I know it’s most likely going to be M240i but still interested in seeing that video 😁

[@miggy2225]

@@kern417 That’s for all B58 platforms. You said you’d make one specifically for BMW

[@peterkukolik8402]

Thank you.

[@MrVuittonDon]

NEED HELP: Any upgraded Pads, Steel Braided Lines, & Rotors suggestions?! Don't want a big break upgrade. (BMW 230i, Bolt Ons, Stage 2 Tune, avg +315hp) This will be for spirited driving on curvy roada in the mountains with my crew on the weekends and every now and then hard straight line acceleration when I am bored. Maybe I would track it 1-2 a year.

[@aldorodriguez1674]

I just ordered a brake refresh. New brake lines, rbf600 fluid and Ferodo racing DS2500 pads on stock 370/340 rotors. Thoughts on this setup? Tires are Michelin pilot sport 4s.

[@kern417]

Should be fine

[@EthanFox]

EBC makes a really good rotor and pad combo not sure if they make it for the BMW platform but i love my yellow pads on my VW

[@kern417]

That's funny i had them on my GLI too

[@f32440i]

Do they create much brake dust over oem?

[@cleancutwatches]

Not related, but what are your thoughts on fueling upgrades for B58 and are they worth it. Like E85, an other race gas. Thanks.

[@kern417]

I have a few videos on my channel if you scroll back

[@xtoxicxskorpion5848]

Hey, im planning to buy a f20 125i 2018/2019 model and chip to ~300hp. I def want to upgrade the brakes as I'm a hard and late breaker. Which pads/discs are recommended? i will mainly use it for (hard) street use and maybe a track day once in a while. Which ones do you recommend?

[@sgtofmarines9455]

Good video bro. I just upgraded to the m performance big brake kit 370mm / 345mm. I was reading in some blogs you should update your ECU to accept the bigger brake kit or you will have a mushy brake pedal. This is done by going into the ISTA software and programming a specific brake setting (SPBR and DSC). Have you heard of this and do you think it’s needed?

[@kern417]

It is not needed.

[@joeyreuser9319]

Great video! Only thing I miss: there are also another smaller brake caliper stock setups. Like mine, f30 330e hybrid. I have it stage 1 on 371 hp and man I need better brakes. Stock i have 312mm front and 300 mm discs in the back. I figured out that the m-sport upgrade (front 340, back 345mm) should fit also. But, do I need to change other things like a brake booster or something else like that?? Or it is not necessary and just plug and play the bigger set?

[@kern417]

As far as I can tell it should be plug and play

[@flaviomartinho1753]

Just the biggers rotors by it self will increase the stoping power Same force produce /further away for the center = better results

[@kern417]

The theory is sound but it doesn't work that way in reality. It's like getting wider tires vs a better tire compound. The material that's used makes a much bigger difference than the size of the disc.

[@flaviomartinho1753]

True but for example a f80 set up if got swapped just the rotors to a 345 lets say would decrease a bit. U should have done some testing before and after on the same spot/ conditions since the only change was the rotors itself. That way we would know for sure.

[@kern417]

@@flaviomartinho1753 it's common knowledge. You can look around on various forums and KZbin videos. It doesn't really matter what the platform is. Again it's like somebody saying they want to go 10-20 mm wider on an all-season tire versus going to a direct replacement summer tire or track tire. It just doesn't make the difference you'd think.

[@kern417]

@@flaviomartinho1753 think about it this way. Yeah you're increasing the torque on the wheel, but you're also increasing weight. And you're throwing that weight farther away from the center of the wheel that increases rotational inertia. How much does that play into affect? Like mentioned, majority of your braking comes from the front wheel and tire setup since all of your weight transfers forward. So what benefit are you even getting from increasing the size of the rear rotors? Running larger rotors also means you have to run larger Wheels. What downsides are you sacrificing by having to go up from a 17 to an 18-in wheel? Lots of factors. But in the racing community it's been pretty well documented that larger rotors primary benefit are for cooling (and looks of course)

[@aj2734]

What about the effectiveness of stainless lines and racing brake fluid? The M performance brake kit is like 2200 shipped on eBay for everything so worth it

[@kern417]

Stainless lines aren't really needed and performance fluid is probably good for track use to prevent it from boiling over

[@mrgapnu]

Looking to buy a 340i don't know if I want to get a xdrive or rwd. I need some opinions on it. I want to mod it heavily around 600-700 whp maybe even more. Will be doing drag races at the track and will be doing a lot of street races. I want to go for 1/4 mile times. I know there's a weight difference other then that what will be the better option when running the 1/4 mile.

[@kern417]

Xdrive for street Rwd for track and some street

[@mrgapnu]

@@kern417 what numbers can the xdrive drive train handle before its a problem ?

[@davids6263]

I accidentally purchased 380mm front brakes for my 340i with the track handling package. I didn’t realize till after that that the edges 10mm of the rotors weren’t making contact. Will I have future problems with this? I really don’t wanna go back in and change em out again

[@kern417]

Please just get the right ones for your car.

[@aidanwilson2330]

Did you end up keeping them as is? Did the outside edge of the disc clear the inside of calipers?

[@crrojo94]

Any updates for the g20 plateform?

[@kern417]

Not at this time

[@chriskamen2152]

why does he have brake cleaner stuck in his throttle body?!?!?

[@jaworq]

can I put M3 G80 front 6 piston caliper in M340i LCI ? I have 19 inch wheels. Currently I have 4 piston 340mm rotors and I could upgrade to M Performance brakes which have 374mm rotor but it's not as significant upgrade as it comes to G80 brakes, don't you think?

[@kern417]

I'm not sure. I don't sell adapters for that setup

[@chriskamen2152]

do you make a bracket kit to fit 370mm rotors on stock 340mm front caliper?

[@kern417]

no i don't

[@Backhandlawz]

Is my mechanic correct in saying the calipers and rotors (340/345mm) do not fit any F30 models under 320i? Something about fitment and changing the hub 🤔

[@kern417]

Rear parking brake can be a limiting factor

[@rob180bhp5]

@@kern417 is there any answer yet for the rear brake shoe size fitment on the f22 as I want to fit the 370s and you kit ? Can f30 shoes be fitted?

[@kern417]

You need to retrofit f80 parking brake components

[@rob180bhp5]

Thank you for the reply ..back plates and shoe kit is that all that's required ?

[@alexarellano425]

Hey man, I have the 340mm in the front and the 330mm in the back, I just wanted to know if I would still be able to make decent power and would be okay with this brake system

can some direct me? i have a 340i with the floating caliper on the rears. wanting to upgraded to 2 piston caliper with 345mmx24 rotor just to match my fronts of 4 piston grey caliper. what else do i need to do?

[@kern417]

just swap calipers and rotors

[@sytralhawk4807]

So pretty much if I just wanted to keep the oem grey calipers but want to make the rotors bigger, I would have to upgrade the caliper too?

[@sytralhawk4807]

@@sytralhawk4807 you either need upgraded calipers to run 370mm rotors or my adapters to run 380mm rotors
