The fear mongering around replica wheels is quite comical.
FWIW, I've run multiple sets of replica wheels on my cars with no issue whatsoever. Adding to that, I've hit some massive Toronto potholes and even had a head-on encounter with a 4" curb (at speed), without so much as a bend.
By contrast, I currently see all sorts of OEM BMW wheels for sale with hairline cracks, examples available in the own forum's FS thread.
My own set of OEM ZHP Style 135 wheels are out of round - no potholes hit since new, not even curb rash.
So many of my cars' factory wheels have become unusable for absolutely no good reason other than crappy build materials - OEM wheels from makes including Chrysler, Lincoln, Acura, Honda, and BMW.
Do your research on the actual wheel you're considering.
ZRacing sells everything from BST wheels (no name - offshore brand, no reliability information), to Fast Wheels (established brand - fully available manufacturing specs).
Also, check the stamps on the inner face of the wheel.
Make sure they have JWL / VIA certifications, and get a set that is load rated as high as possible (Minimum of 1500lbs / 685kg +)
