for body kits, some kit will have better fitment then others even from same mold(body shop told me)
i have the replica amuse kit from shine auto(same kit UAM offers, UAM made it and offered it). The body shop was amazed with the fitment! but depends on the skill of the body shop. i took it to two shops, first shop fit the front bumper like crap, had like 1 finger gap below headlights.
second body shop fit it really well. but there was a crack due to shipping. BUT, Ken at shine auto handled my insurance claim and i got my money for fixing the crack
