[R3MIX_G20]

Hello, I keep coming across mixed reviews, so I thought I would put it out there and see if you guys can help.

For my 2020 G20 330i, I just purchased front M Sport calipers from the M340I. My question is can I run the 374mm G30 rotors on the car , and if so, would the calipers still be a direct bolt-on (and/or any issues) given the extra inch in rotors?

Any feedback would be appreciated.

-thanks

you cant use 374mm rotors with standard M340i 348mm Msoprt caliper, but if the caliper you purchased was option with Motorsport Engineering package, that caliper run 374mm rotors, take a look at the back of caliper it tells the caliper fit 348mm or 374mm

Look at the dimples on your caliper:

- center dimple hole = 348mm rotors
- top dimple hole = 374mm rotors

With 374mm brake discs you can have 18" wheels. I have M Technology package and style 796m 18" rims for winter set

Nice information to know! I'm sure the clearance is super close

That guide is incorrect. The 348mm and 374mm pads are not the same. They are not interchangeable. See the below video.

No doubt you and the video are correct.
