I tried searching but couldn't find this specific topic. Which of these upgrades to a 335i gives better braking power? (Note, mine's an E90). I will be upgrading to the M3 Master Cylinder regardless of route.

-M3 Brakes (In this case I'lll be upgrading to M3 rear axles + diff, so this'll plug right on)
-F30 M Performance Brakes

Thanks ahead of time.

(e92)M3 uses the same front calipers as 335i, not sure on the rears.

e9x m3 brakes won't mount on none M unless you replace the front and rear uprights. Regardless F30 are better brakes.

Wrong! None M 34116773201 vs M3 34112283361 Only pads are interchangeable.

Whoops, they look exactly the same, didn't realize they had different specs. Thanks for the info.

A lot of calipers look a like because usually they are all made by ATE. Similar design are found on VW/Audi/Bentley, some Jaguars, Volvo and ect. But they are all diffident.
M3 caliper has larger piston thus the larger brake cylinder and also the carrier has different spacing, the bolts won't line up in addition.

I knew it(M3) had a larger master cylinder and should have figured the caliper had bigger pistons because of that fact. Thanks again

I was going to replace the uprights too. Any advantage in handling if doing so anyway?

I'll probably go the F30 M Performance route then based on braking power (bonus for how it looks too). Time to search if they fit the M3 rear axles.

When you go to M3 uprights you will need M struts and M shocks. The front control arms give more negative camber and rear control arms allow for better shock articulation so yes, handling will be improved.
F30 fit the E9x M3 rear but you will need M rotors witch will be bigger than the front rotors so I don't recommend you going that route

You can swap the rear control arms separately anyway right? Unless I'm mixing that up with the front control arms.

I'll replace a full set of calipers and rotors, front and rear. Why do you recommend against this?

Yes you can swap the rear control arms and have m3 upright with none m3 control but that is giving away the single benefit from having m3 components in the rear. I'm against because F30 won't mount on E9x M3 front upright. Only on none M. So if you go with rear M3 E9x upright and F30 brakes you will need to use F82 rear rotor that will be bigger than your front. All of this has been covered on the F30 brakes thread.

Ya I've been reading up alot about it. I understand the issue a bit. I'm confused why you did it on your own car, but you don't recommend it?

As much hard driving I do in my 335i I have to wonder why you would ever need to go with anything else than stock. Stock brakes are more than capable of stopping my 335i from speeds in excess of 185mph on the autobahn. If you have no confidance in the stock parts than you are running substandard replacement parts.

It's not from a lack of confidence in my brakes. It's simply that I know the brakes were spec'd for this car at the stock power of 300hp. I plan to increase that power to 400-500whp. With greater power, comes greater responsibility. The M3 has stock power of 400hp and has better brakes spec'd. Because I'll be near that power, I believe it necessary and responsible to upgrade my brakes.

I've yet to track this car, but would like to slowly set it up for tracking. Because of the modifications I'm planning for the car, I can easily swap to M3 brakes, but noticed the M-Performance ones are nicer looking, and am now learning they are even better. So in short, I'd like to upgrade my brakes to handle higher horsepower, to be better on a track, and it's simply a bonus if it looks nicer.

You are confusing yourself. Re read your questions and my answers to your questions.

Simple. You aren't driving hard enough. How is speed here the sole factor? Because is 185mph? You cook your brakes doing 18.5mph.

Speed is never the sole factor, repetition, speed, condition of the equipment, condition /traction of the tires, road surface...

As someone that has done the complete F30 conversion along with the M3 master. It's much easier than a M3 conversion.

Go F30.
