I added 380 mm rotors to F22 M240 using stock blue calipers with new mounting bracket adapters.

There was no clearance issues with 18” stock style 436 or bmw oem style 307 for track tires.

Looking at aftermarket and running into issues with enkei and VMR 18” with inner wheel clearance not side clearance to the back of the face of the wheel.

VMR could not provide me inside diameter of any models but suggested creating a template of my brake dimensions and sending to them. Apex has fitment guide for 370 mm but not 380 for F22

I believe my best chance is with a flow form design. Any recommendations?

Thank you

I have Apex VS-5RS 18x8.5 ET40 in the front and they clear 380mm brakes.

Do the pads even reach the inside edge of the rotor? Not sure this upgrade is worth if it doesn't.

[BillG2AB]

Not an issue. F22 Blue calipers use same brake pads size/dimensions (are interchangeable with OG M2 with 380 mm), using larger rotor provides more sweep area , leverage, and thermal capacity to manage heat build up. No fade on big tracks

[BillG2AB]

Thank you smellygreek I ordered EC-7

[BillG2AB]

Test fitted them today on fronts and you were correct they fit over 380 mm rotors with oem pads with a few mm for clearance
Many other after market and bmw did not fit.

[Moodi]

Would you mind sharing wheel offset for EC-7?? And are you using any spacers??

I was looking into getting them and have the same rotor setup 😄

[BillG2AB]

35 ET. No spacer needed

Since 380mm is the stock F8x rotor size, I'd assume it's safe to use M2/3/4 fitment guides when it comes to brake clearance (obviously not width/offset)

[Antwanr942]

Which brackets did you use? Epytec said 380mm rotors wouldn't find on 18" rims but obviously that isn't the case.

Cheers!

Hello and sorry for wake this thread up. I have 2018 M240i with stock brakes and its time to replace brake rotors on front. I am confused about the informations on web that are 380mm rotors going to fit in stock 436m wheels without spacers? I know that I need to install a adapter for calipers but I do not want to change car' s dynamics so I do not want to put 10mm spacers for wheels. Did you install any spacers or is there enough space with stock 436m wheels? I couldnt find PM button I wanted to ask directly on thread.

Thanks in advance.

I am also curious and cannot get it clear - are spacers required or not?

[SmellyGreek]

I believe 10mm spacers are required to fit stock 18" wheels over the 380mm brakes, but I can't find a reference link to confirm for you right now.
