Dave,
Have a look here:

"$219.95 - You can completely dial on your chassis tuning by using an adjustable stiffness front and rear swaybar. This is the RACE VERSION (very stiff)front bar kit that goes over the TOP of your trailing arms for maximum ground clearance."
I've not used it and was looking for more information but can't seem to find much of anything.
I was told by a local kat that this is the best bit i can get for the type of driving i like to get up to.
