Just took the MY25 delivery, immediately spot the door panel fitment issue.
First thing noticed, driver side door does not align with the rear quarter panel. BMW spec it as +1.3mm to -0.3 mm, where + means door bump out and - means quarter panel bump out. I don't have the Supra special version of ISTA so the spec was from BMW Z4. This is barely within the +1.3mm.
For reference, passenger side has a perfect alignment, almost flush. These panels should always follow the principle that the one in the front should bump out a tiny little bit or flush to reduce wind noise and drag.
Now here is the real issue: This is not caused by door striker alignment. I moved to the front end of the driver side door. It sticks out to the hood. BMW spec it to be +0.8mm ±1.1mm, meaning either the hood should stick out for a max 1.9mm, or the door can stick out for 0.3mm max. In my case, this is the exact opposite. Door sticks out way more than 2mm, more than 7 times over the spec. That explains why there was excessively amount of wind noise on my way back to home.
Again as the reference, the passenger side looks perfectly fine, within the spec:
Now look at them at the front, Driver side door panel is bumping out from the hood, while passenger side is not.
There are two door hinges hold each of the door. It's a simple fix, loose the upper one so it's just able to move, push the door in and secure these bolts again. These are T40 Trox so the bits should be easy to get. They do require low profile bits and I'll have to get a new set, current set doesn't fit into the tiny gap between the door and the body. Torque spec is 19NM.
Panel gap spec, and torque for the door striker if these need to be adjusted as well. 21 NM is standard for most BMWs. I took them from Z4 since unable to get the ISTA for supra. They should be identical.
This is such a typical issue for BMW, I own another BMW and it was much much worse. 5 panels were not aligned from factory, and hood won't close unless you slam it. I blame the Spartanburg plant at the time. But nope, BMW just don't care about checking if all the panel gaps even for these low volume vehicles, and apparently Toyota QA is not playing a role here.
