Ideas for what everyone is using for traction devices?

Looking for ideas as to what to go to for traction device. I am using a pinion snubber now and it kinda works. I am noticing that the snubber is bending in the floor some, even after I added a plate. The plate I used is 10 gauge, but it seems it is not enough strength there.
I am looking at the ones that go on the spring, my springs are Firm Feel +1 HD.

Both my Mopars hook hard on the street. Only thing that's beat me out of the hole so far was a Nissan all-wheel-drive GTR with slicks. Properly adjusted bolt-on slapper bars, Nitto Drag Radials and (2800lbs - A-Body & 3200lbs- E-Body) SS spring rated hundreds of pounds below my car's actual weight (both weigh in around 3700lbs).

The 3200 lbs springs on the E-Body have a bit too much spring rate, (which gives a harsh ride with no weight in the car), so I'm going to try a set of the lighter 2800lbs SS springs on it for a more compliant ride. Use passenger side springs if you want a bit more ride height and driver's side springs if you want a bit less.

I know the old Wive's Tale about how this doesn't work on Mopar's, but even Bob Tarozzi checked out my A-Body and was impressed. Best rear suspension I've had in 4 decades of trying all the above and then some.
