Can anyone verify if the ZTK option comes with the larger 374f/345r rotors and larger Mperformance calipers on the 2022 M240i US model? That option code has been used for a few years and is formulated differently depending upon specific model and perhaps markets (US vs Euro etc). In the US order guide it only shows subsets of 1W0 and 33T within that option, while other models show other subsets for that option such as 2vc (mobility package) and even the 7m9 (shadowline); as part of the ZTK option.

It is really strange that there is absolutely NO mention of bigger brakes in the description of the ZTK option in the US order guide. I am amazed at the dearth of any description of the 33t (M tech package) for this specific model for the US.

Also i can find NO stand alone option for the larger performance brakes on the M240 on the order guide i have?

Note: i have searched this forum but found no conclusive answers to the above. I did see a schematic of components for the 33T but no validation it was specific to the 2022 M240.

So for anyone (US) that has received a M240 with the ZTK option can you verify if the brakes are the 374/345 and larger calipers? I think the Euro spec ZTK does include the larger brakes. Or has anyone seen a 33T description specific to the 2022 M240 (US)?

Also what is the rotor size for the standard M240 (non ZTK), is it 348f/345r?

I just measured best I could with the wheels on and straight edge / tape. Looks like they are the 374/345. Calipers are enormous.

Agree the ZKT package is short on details. I'm really glad I got it as I think it's the only way to get the wider 8.5 / 9.5 wheels and 245/255s.

Actually those wider tires/rims are a no cost option, option 1VZ is a no cost option for the M240i that is 245/255 on 8.5 and 9.5 rims.

Right, 792 rims vs 893
