I've tried changing the file name, with no success. I actually found out earlier that I couldn't update my computer not because of storage, but because it was already updated, so theres that. Storage issues may still be a reason it doesn't work.
I can see why you think that. This car has a larger gap between the wheels and the rims, so I tried to add a plate of space to replicate it. Also, the space around the front wheels is 1 stud longer than in the back. This is because the wheels do turn, and the added space allows them to rotate more. If I changed the wheels to be bigger, it may fit in the front, but not the back.
