M3/M4 brake conversion for all F3*

Belong · 02-06-2021, 06:43 AM

Hi guys

New to the forum here...

Im selling brackets for the front and the rear for the F3* platform to succesfully use the M3/M4 380mm front discs and rear 370ers discs on the f3* platform.
1 series and 2 series also available but will only go in the front, since the rear have a 160mm handbrake ( with which this conversion wont work.

You can contact me on instagram: EstorilV10

Im also doing custom Big Brake kits for lots of other cars as well..

I have adapters for the 340mm Msport BRembo calipers to 380 m3/m4
as well as adapters for the 370mm MPerformance calipers to 380 m3/m4 discs

and for the rears to use the 370 mm M3/M4 rears discs

Rears will only work if you have the larger 18.5cm handbrake.

ill try to update this post soon with some pics , if there are people interested..

If you fill in the last 7 digits of your VIN on realoem.com

go into the brake parts menu

it shows you in the handbrakeparts submenu which one you have ...

it shows with a D: 16 or a D:18.5 ( D - Diameter )

Ah you're talking about the brake disc dust shield being either 16cm or 18.5cm, gotcha

Sorry not the dust shield, the supporting ring inside, number 6 in this diagram? Didn't realise they came in different sizes.
Have you got a picture of these brackets? How have they been made/designed/tested?

Correct, over 90 sets sold already.. proven good to up to 640BHP on a driftcar, and yes theyre very quality made.. no backyard tuning crap

2liver2life · 02-27-2021, 10:08 PM

Are you shipping to the US?

Belong · 03-03-2021, 06:23 PM

I could.....

SantaEugence · 03-04-2021, 01:33 PM

Are these the same ones that required part of the rear caliper body to be trimmed away...

No difference in RWD or Xdrive... Xdrive always have bigger rear handbrake - 18.5cm so rear conversion will also work..

Do you have any pics from the back with your bracket installed? Why is no one doing this mod, it seems amazing and functional?

Why is no one doing this mod...

i think over the last years weve sold over 100 sets.. the only downthing about this setup is money.. M3 rotors are alot better then the crappy mperformance or Msport ones and yes they cost a lot more.. And they look 3259329532952379752 times better.

MikeeM · 01-25-2022, 11:59 AM

Hi, I have the front brakes from the M4 at home and I'm wondering if it is worth for me to put it on the F32 430d. How much would cost the front brackets stand alone?
Thanks

Well it's very likely because 10mm is not a big difference for this car. The same calipers bolt on, without any additional bracket (that also requires shaving the upright), with readily available 370mm rotors. It's almost a no brainer. If someone is really that interested in their brakes they will go after a GT kit, Ap Racing, etc.

Boostedphil698 · 01-27-2022, 09:01 AM

Would have been easier to just bolt on the M Performance BBK designed for our cars. The kit uses the same calipers as the F8X cars. Just my 2 cents.
