This is basically the "Partially Upgraded" that the other markets get so the spec sheet for that is basically the same.

Almost $5,000 in labor holy shit.
Those are just the wire harnesses in the engine bay too. No need to take panels and crap off inside. It took them about 20 hours?
82122-WAA04 has taken me about an hour before. lol
Apologies, I meant 374mm, it was a typo. It has larger calipers, they accommodate that size rotor. You can see it in the press photos and videos. The 374mm calipers have space between the piston half circles and the edge of the caliper, and the 348mm calipers do not. I am not incorrect.
Again...
274mm front rotors with larger calipers. This has been documented in another thread about OEM brake upgrades. Short version: Already on a bunch of different bmws. M240i/M340i/M440i offer it as part of the cooling package.
