Does anyone know of a wheel hub that would fit an xb but with a bolt pattern of 4x114.3?

 

I don't know, but I'll tell you this much. A 4x114.3 bolt pattern is the worst bolt pattern that you can get. I know. There are many wheels that I would like to slap on my Sentra, but about 99% of those don't come in my 4x114.3 bolt pattern. Most of those only come in a 4x100, 5x100, or 5x114.3 bolt pattern. I personally would not bother trying to get a hub in that bolt pattern. By the time you end up scoring some hubs & some money that you spent getting them & installing them, you could have bought some 4x100 wheels with that money instead.
