I have it also on the front, cut 2mm of the rear of the front lower arms.
Didn't cut the upper arms because normally I run 2mm of caster shims behind the upper arm.

Have you considered fabricating a more elaborate battery tray that fills in the slot in the chassis and then overlaps the chassis a bit on the side and the back? You seem to be losing a bit of what you've gained by adding all that weight on top - but I could be wrong.
Well it's funny you mention this, my first idea was this:
But the lowest quote to get it fabricated was $120
So when I found the Tungsten for $40 and it is reusable if I switch to a different chassis it was a pretty straight forward decision.
But I think it actually lowers the CG compared to a brass tray or the brass hudy weight. The upper 5 blocks I might put them between the tank and radioplate supports instead of on top of the other blocks.
Another option is to machine down the brass battery tray so the Tungsten plates will be lower.
The problem is, that it is pretty much impossible to drill or cut the Tungsten.
Even with Diamond coated drills or cutting disks.
