Anyone running 20X10's without having to cut/modify the factory wheel tubs? I have a Chris Alston Fab9 housing that I purchased brand new. When I bought it, I had it narrowed 1" on both ends. I've also purchased a set of 20X10 rear wheels with a 5.25" backspace (I think?). Anyone know if I'm going to run into problems with this? Am I going to have to widin the factory tubs? Thanks in advance for the help?
