I need a 4" min to leave 1/8" clearance side to side, might fab 4.25" just to have a little room side to side. Pivot point would need to be at 2-2 1/8". So nothing too extreme... Rear is a whole different deal. Gonna turret rear, and tub arch. Atleast that is the plan. Possibly raise subframe if that doesn't get me where I want. Thanks guys. Gonna go ahead and order 1 side of sleeves to mock up in a few weeks and go from there.
I would imagine that your coil overs will hit the back of the wheel with the diameter you are talking about using.
At full droop there isn't loads (about 3/4") between the back of my standard 12" steel wheel and my coil overs.
