Well this is the poor mans mini tubs but this is how it goes.
You make an 8-9" vertical slit in the front corner of the inner wheelhouse. You take some flat stock and a sledge hammer, move the inner wheelhouse where it attaches to the floor and move it toward the frame. I used a straight edge and lined them up with my leafs.
The front moved over an inch and the back maybe a little less.
The slit you made will open up like a
pie cut. Weld in a like piece of sheet metal, undercoat and you're done!
If you want to hide the very slight buckle on the trunk side, just lay down a bead of silicone, smooth out with your finger and coat the trunk with speckle paint.
I highly suggest running a pan hard bar to keep movement to a minimum.
With the 17x9 with a 5" bs and a 275x40x17 I have well over an inch to the wheelhouse on the front edge. I had 1/4" before moving them in!
If you just move the amount stated, your inner qtrs will squeeze right back in. They are touching but you cannot tell.
