I'm sure that 70% of modders here know 'bout this problem:
Take car from (example) GRID and convert to zmodeler
Take
ORIGINAL elegy and it's dummies as reference (use dummies instead of makin it)
then install car ,and suprise all dummies u used shrink parts like doors,hood,boot...
What to do to make parts in normal size?
And if u need picture i'll upload(but i'm pretty sure that it isn't necessary)
