I have a bunch of OEM parts, but I will warn you that I am an exception to the typically poor products they put out. Reason being is that all the parts I have were made for my car while my car was at their shop. The control arms are working out well for me, they were approved by both a verified suspension engineer and my awesome alignment guy. They only fit correctly imo because as I stated earlier, they were fabbed up on the car. There was no jig which is why other sets don't fit. I have a set currently on my B14 and on the NX, the NX set will be up for sale as I am in the process of testing Chuck's adjustable ca setup.
I also have a lower control arm brace which is fine and a set of fender braces which are working as designed.
And even though all is well with the products I currently have, I won't be spending any more money with them because of the manner in which so many other issues went unresolved with my forum brethren.
