I am just going to chime in and tell ya that if you go wider with the arms. You can always make up an inch or so with different offset wheels. So if you go with +2 arms, you can get 4/1 offset wheels and really only be 1 inch wider on each side not two. I know alot of guys go with after market longer a arms to get the longer travel stuff. I am just telling ya for somthing to keep in mind when considering a set up.
