Boxing the rear arms will help, not really a big fan of poly bushing in the back thou, too much binding which will lead to wheel hop

There's some info on beefing up the frame on 5th gen Elcos, where the rear control arms are attached, using 2-inch square tubing etc. I'll take a look for that article, and If I can find it, I'll post it.
If running big power & torque, even adding some gussets in the corners where the cross frames meet the main frame, is simple and helps stiffen things up. A beefier cross member at the rear of the frame, just ahead of the bumper, also helps.
Boxing the control arms is always a good idea, and fairly easy if you have some plate stock and arc welding equipment.

I forgot to mention, that I used 1/4" plate for gussets, on the lower control arm brackets on my 4th gen project. Those brackets on most frames don't look very substantial, if some high-torque is put on them.

It will certainly stabilize your ride, especially when you are hitting it hard.
