Do G20 M340i brakes fit?

[eforty6_m3]

Has anyone tried retrofitting the G20 M340i brakes on an E46 M3? Do they fit? This isn't something I'm necessarily looking to do, but at some point down the road I'd love the look (yeah, I said it...I don't track the car so it would be primarily for aesthetics) of a BBK. So I'd be curious to see if these would be a viable option.

On a completely unrelated note, here's a photo of my newest daily driver for attention 👀

You have both cars...10 lug nuts, 4 caliper bolts, 1 brake line, maybe 4 rotor securing screws later...you can give us an answer? But I'd assume there will be need for hub shimming, etc.

Correct, I do, but was hopeful someone had already done the work and had the answer for us.

The 340i is fairly new, so I doubt anyone has made brackets for those. There is the F80 M3/M4 setup. The F30 335i got 4+ different colors for those calipers. That F30/F80 generation caliper looks much better, imo and might even be lighter weight along with the rotors.

Good call. I'll check out those other kits when the time comes. Thank you for the feedback!

aren't g-series 5x112?

They sure are... but that doesn't preclude the calipers from being a fit, unless I'm missing something.
