To be quite honest, I'm not sure....
I tested mine on a high traction surface (aka carpet ) and it lifts the LR slightly on a hard instantaneous reverse, but I've never really noticed it in a comp situation. Does yours do it under normal driving conditions?

That's really odd. I would make some suggestions such as link placement, shock springs, shock oil, etc., but I think you've pretty much built yours like I built mine.

Have you checked to make sure nothing is binding anywhere? Also, make sure your axle shafts are spinning freely.

Cocking a rear wheel in reverse is usually caused by under/overdrive. When your reversing the front is going faster than the rear. This can cause the chassis to "wind up" and cock a wheel in the air.

Could it be a weight issue also ? I'll let you know if mine does it when my wheels show up

I may decide to go a little stiffer in the rear, but with this rig being significantly lighter than my previous sporty, I wanted to try these first.
This set of shocks is about 10 grams lighter than the other set.

Wish i could find some lower shock ends like you got on the front. i need the clearance badly
