What do you mean by trim?
Regarding JB4: My dealership told me that if I do get it, a strong suggestion is to remove it each time I would go for the service or any sort of issues and I am friends with the main guy there, but he said someone might notice and still flag it in the system as a tuned car.
Same thing is with the lowering springs, they are flexible with me because I am friends with the guy but if for example we have any warranty issues where they need to take pictures of the car, then they would need to have the springs switched back to stock.
