How much tire clearance

[fordsbyjay]

How much tire clearance is recommended in the back of my car. I will be running a torque arm with a watts link. I am trying to determine if I am going to just to trim the factory rail some or replace it or just move the whole thing over. The latter seems like the most work so I am not too keen on that idea. LOL.

I trimmed the wheel well back to the frame rail.


As you can see I still have some room if I trim the frame rail lip.


There is about 1/2 on the outside. I will have to remove the outer wheel well as well because it tapers in too soon crowding the tire.
