F30 330d Brake Upgrade

[mattwade24]

I currently own a 2013 F30 330d, which runs the standard brake set-up.

I'm looking at purchasing the M Sport brakes (Blue Callipers), Front rotor: 370x30mm / Brake Caliper with 4 piston, Rear rotor: 345x24mm / Brake Caliper with 2 piston.

Will these be a bolt off bolt on job, is there anything else i'll need? Coding etc.? I've had a quick look online and can't find much information.

Any help appreciated. Cheers!

Check out the UK forum on e90post forums. There is a guy who has been selling the kits.

What size wheels do you have? There's not much clearance between the M Sport caliper and a 19" wheel so if you have 18" they may not fit...and don't forget to inform your insurance company...

Main thing to check is the size of the piston on the brake pedal match too.

If not the feel might be different based on ratios of pedal travel/pressure vs calliper clamp force.

Good to know if there will be any issues there. Usually they'd all be the same but good to double check.

Not sure if this is relevant:

It’s not a job I’ve done.

Wow people on that thread need to read how brakes work.

It seems they think you can literally code brakes feel, linearity, etc.

There is so much variability in temp alone, then add in age/wear/component variance (disc/pad materials)... no way would anything useful be 'coded'


So I'd forget all the coding stuff wrt feel etc.
The DSC coding specifically is likely for emergency brake assist type stuff, or error detection thresholds for different calliper types if they stick etc (4 piston vs sliders etc)

All the important stuff is done via PID feedback, and I *think* dsc still operates open/closed, not partial state, so not sure what coding might change.

If coding were critical for basic operation then changing brake pad compounds would throw errors etc!

“Wow” indeed. I’m not sure if this is aimed at me or others, who knows.

If it is I do not need to read “how brakes work”. I know how brakes work. I know lots of things. I know that I aim to help others in my posts, occasionally I attempt humour. Though it can be dangerous. I try and avoid rudeness or spelling mistakes.

I do know the op asked a question. I have answered his question by linking to an F30 or 31 brake upgrade and coding thread on another forum.

[Mr Whippy]

Sorry if you took offence but it clearly says, 'wow, the people on that thread'

So not you.

The thread is helpful, just my advice to the OP here not to worry about many of the issues raised there wrt coding.

[helix402]

My mistake! Thanks.

[mattwade24]

Thanks for all the replies!

Wrt the wheels: I currently have 20" 405 wheels which I will continue to run through winter, and may get some 20" 666m wheels for summer next year.

I agree that the coding won't change the feel of the pedal, what the other thread is describing sounds like a placebo effect! I just wanted to make sure I wasn't going to get any errors or lights by making the change.

Thanks again

I have those brakes on my car and they are different to normal road car brakes, but in the end they're 4 piston monoblock on huge discs.
They offer power over travel and feel.

I'd have no concerns going for them despite that on a fairly heavy inert automatic car that can do big speeds.


If I were wanting to do lots of H&T shifting in a manual road car though, probably not ideal.

Also I bet a all the 3er use the same master piston, so these big brakes won't have an optimised 'motion/pressure ratio' (not sure on actual terminology you use).


Good luck with the upgrade though, they do look very snazzy, and will look much better under very large alloy wheels!

I have them, they are leagues ahead of the standard anchors.

Feel/modulation is excellent. Only gripe ? They should be standard fit.

Something wrong with your standard brakes? A 330d is hardly a rocket ship.

There not cheap if you get the 370mm discs and calipers. You can get the 340mm discs with calipers which is what I have on my E92 and there quite a bit cheaper second hand. The calipers cost me 300quid, normally the 370mm calipers are around 500.

[mattwade24]

Thanks again with the replies.

Nothing wrong with the standard brakes, albeit they look lost under the 20" performance wheels. The cars coming close to needing a new set of discs/pads, so it's an ideal time to upgrade.

I'd agree it's no rocket ship, but it's hardly a slouch after a remap, and there's plenty of weight to slow down/stop!

Should be straight bolt on. The 370mm version isn't going to be cheap.

Probably would have worked out cheaper to have bought a 335d :-)
