One thing to keep in mind is when you lift the front end, the wheels will actually go closer to the engine so a non-stock offset on wheels can help reduce rubbing. That's what I found anyway with the Bilstein shocks. So having 0mm offset on my Method wheels seemed to fit on the truck perfect with a 2 inch lift.
what size tire are you running?
another questioni, what does the brand of shock have to do with rubbing?
