Yes, the 373m wheels were my first choice. Unfortunately, they only come with the M-sport package which means I have to give up all the BMW Individual options including the illuminated BMW Individual door sills. I will find a way to swap them out after the car is delivered.
Confirmed that cars from July production onwards will receive the same N63tu engine that they put in the GC. So yes, it will be the 330kw (445hp) version. That's one of the reasons why my order was held up till now.
