I am mounting a set of hard mounted bags over my rear shock springs on my Barcalounger.   I expect to see some "loaded bag deflection" when going over bumps and I am seeking some actual knowledge of folks who have done this sort of situation before.  

How far out from the springs should I space the bags ???    Opinions ??

I seem to swing from no offset (let it rest lightly against the springs for constant alignment support) to 1/4" to 3/8" to only allow occasional contact during bumps.

They are "semi-hard" bags made up of fake leather viewing exterior with a polyethylene hard "inside toward the springs" wear surface.

I foresee a 3/8" offset naturally deflecting over time to partial constant engagement.  

If I set it up at a continuous light contact I fear having it turn quickly in the direction of simple wear through.

I guess I am thinking once I see some attempted wear through I would drop in a 1/8"thick  sheet aluminum wear surface that could be renewed as needed.  

Your point about spring squat making the spring diameter grow is a good one .....

Ditto that.  They should not be allowed to contact the shock at any time.  I did the same thing to my Mutazu bags, and some throw over bags.
If possible, you need to put a "dummy bag" where the real bags will be going, then take it out and bounce the bejeeze out of it so you see where it will touch the shock.
