did this a while back, I used some thick plastic washers and glued them together. I also put them on the rear (or would that be middle bolts) and you can see lean difference
don't have a picture of it flexing, but here is a video link

MetalCloak 2.5 ARB lift
I am retiring in a few months and building a expedition type Jeep.
*The skid was added for a little extra protection when out in the middle of no place or just down the road.
*Lift was added to give just a little extra clearance, I pick MetalCloak because of a deal I found and that it was more...
just a short wave from NM & CO. got a 2013 Rubicon Unlimited 5-speed auto with 3:73 gears. So far only an s-pod and MetalCloak 2.5 ARB lift, in the process of adding a Viair air supply system. Later will come a ARB or AEV front bumper and AEV read bumper.
