50i M performance brakes

[cralmandi]

Anyone put these on their 50i and is it a decent upgrade from stock. I hate the look of my rusty stock rotors and calipers but almost $3K is a little spendy. Other option replace stock rotors with drilled and paint the calipers. [IMG][/IMG]

There's a thread already for this. Tons and tons of posts

OP, here's the thread djrabbi is referring to, I think -

https://f15.bimmerpost.com/forums/sh...=M+performance

Still, I'm curious myself to hear from more 50i owners who've done this MPBK. Obviously it's a big upgrade if you own a 35i, but as a 50i owner who's interested in this kit, I'd curious to hear more feedback. The 50i stock rotors are the same size as those in this kit, I think? No? Any detailed feedback from a 50i owner who's gone from stock to this kit?

I have them from 50i and don't feel much difference besides the wow factor. I wouldn't do it unless you have $2000 you want to blow

Thanks, I appreciate your reply. Agreed, visually it's a huge upgrade, but I'm skeptical there's much performance upgrade from a stock 50i, although...

What is the huge increase/upgrade?

[ponytuning]

Can't speak of the MPBK for the 50i, but I had the MPBK on my old 435i. It was a night and day difference on downhills, great stopping power compared to stock. I had buyers remorse until I had to break from going 90mph downhill on a passing lane to an almost complete stop. Then I was convinced it was a better upgrade than the MPPK and the MPE.

I did my upgrade for around $1k. Calipers from a wrecked E70 on ebay, Bendix rotors, whatever pads you want. It's worth it.

I'm convinced you didn't install these properly or have them coded incorrectly.

As much as I love when people start whole new threads because they didn't simply search. Yes the brakes are an upgrade. Both aesthetically and performance wise. The rotors are much larger than oem 50i but the 4 piston calipers are going to be the money maker. Not necessarily in every day slow braking but in the ability to slow the vehicle down more efficiently from higher speeds. So aggressive braking. You can Google plenty of articles on the performance difference of fixed vs floating calipers. And if you're not sure oem is floating. Fixed is the upgrade.

Dealer did it so what do you want me to tell you?

Nothing. Its been tough to follow. In one thread you mentioned getting them installed by an indy in Newark. In another you mentioned dealer had no idea what you were talking about re: coding for the MPBs. Whoever did install these for you and coded them... probably should give it a second look.

Yup. I took it to another dealer who actually knows what they are talking about lol. They took everything apart and re-installed and bled the system. Paid $500 again for same situation.

Maybe the pads suck? But few members been running the powerstop ceramic pads. I'm thinking of replacing rotors and pads all over again

Why do people complain so much when a new thread is started simply scroll on. The threads I found are like 5 years old, thought there may be a little new info.

I installed them on my E70 50i (E70 50i stock brakes are same as F15 50i). HUGE upgrade looks wise, city driving you won't notice much difference, however the late night blasts to triple digits on empty stretches of roads we are all guilty of is where you really notice the difference, or if you are towing/stopping on a grade. Kit is easy to install by yourself if you have a pressure bleeder and ISTA to do the coding.

Order from your dealer and save $$$ (never thought I would type those words). I got mine for 2280 + tax from dealer after negotiated with them. Will save you on shipping too. Box is HUGE and heavy (300lbs). They used a forklift to load and I split the box open inside the car I used to transport and took each piece out individually when my girlfriend gave me side-eye to help unload the huge shipping box 😁

Cool thanks. I'll check dealer. Cheapest I found online right now is $2495

It's worth asking and usually you don't get charged for shipping when you order from the dealer, which can save hundreds on a box this big and heavy

Me want so bad

Lol because it just clogs up the forum with repeat topics. Which in turn makes it harder for those who actually search to find a consistent answer. Now those now have to sift through dozens of threads with incomplete information instead of just one or 2 with all the info they could need. Not to mention all the info you could need is on the first couple pages. All that's on the rest is the coding and maybe some cost updates and photos of install.

Plus it just shows people don't want to take the time and read through the effort that others have put forth. And while the thread is a few years old it's posted in almost weekly.

It's obvious when you have zero reputation. But please notice I answered your question regardless. It's just forum etiquette.
