Lower arm bag cup v/ plates

[ibad57]

I done my first air ride drop this weekend and need some feed back on the front bag install. The bag seems to touch lower arm during 1/3 of its travel to top. I will describe components install and ask weather or not a plate would be better for lower arm
dom 2600 bags
suiside doors cups and top plate 3/8 cut off the cups
Southern kentucky classics 2 1/2 drop spindal's
This combo lowered top of wheelwell from 32 and 3/8 down to 24" this seems perfect tire clears fender when droped to 24" bottom turned and stright.
But bag sags over cup's top plate and touchs lower arm
with 3" between drop travel how much bump block should i add to protect bag?
I feel a lower plate better surface for bag to rest on because bag acually rolles over top of cup when lowered. any opions?
