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
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!
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
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.
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 🙏🏾
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 ?
I’m trying to do an F80 M3 brake conversion on my F30 335i, I get the calipers but I can only fit 370mm rotors. So what you're saying is with your brake upgrade kit, I can move the Caliper mounting point to allow the standard 380mm M3 rotors? I understand how the front works but the rear is where I’m getting confused. With your upgrade kit, will I also be able to run stock M3 rear rotors 370mm?
I have a 2015 435i xdrive, came with bigger brakes in the front but the rest look very standard. Can I upgrade to the Breton blue caliper in the rear without any major modifications?
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
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.
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.
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.
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.
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.
@@flaviomartinho1753 it's common knowledge. You can look around on various forums and RUclips 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.
@@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)
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
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
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 🤔
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?
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?
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?
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?
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?
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 I use 370mm rotors instead of 340mm ?

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

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

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

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

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