The rear stabilizer links I assume? I was looking at those the other day and they do look puny in comparison.
Maybe, if you have the money, go to a 4WD place and see if they if they can hook you up with detachable links. That's a must for going off-road when the terrain is ultra-even as even on a truck or Jeep you will have issues. Then, you'd have 4 wheel independent suspension!
Something to keep in mind when talking about the Element suspension, especially on rough roads - the front anti-sway bar is quite a bit stiffer than the rear one. You can tell by looking at its diameter, or by putting one front wheel up on the curb. You should see more suspension depression in the opposite rear wheel.
That, plus the heavier front end, means that on uneven terrain, you are more likely to fly a rear wheel than a front one. Put a front wheel in a hole, the opposite rear is likely to leave the ground. Given that the E is, by default, a front wheel car, that is not a bad thing.
