My friend rollintroopers (that's his screen name) has done this mod. He just pulled and modified a rear sway bar from a second gen trooper. Anyways, he says this was the single best mod he's ever done for the handling of his trooper. I have looked at what he did and it was pretty straight forward but I can't say I could tell you exactly how he did it. You could probably send him a PM and get a little info on the mod. It's supposed to make a lot of difference on how they handle.
