What are body dampers?

I don't see how a body damper that is made to supress chassis stiffness is going to eliminate rear wheel hop.

I've got SPL rear traction links (SPL RTR Z34) installed, but haven't been able to utilize them since I'm still on the stock "bars of soap" Bridgestones. If I still get hop after installing the Yokohama ADVAN AD08 summer tires (coming in APR 12), I'm going to install the Energy Suspension 350Z polyurethane rear differential carrier bushings (7.1119) in the winter of '12.
If that don't stop it, then I'll try replacing the rear lower link bushing (nothing available yet-TMK).

The dampers stop vibrations that can cause cracks the frame, not anything you can feel in ride quailty or noise. The higher spring and shock rates cause the problem. The RX-7 R1 (1993) could have used them as frame crack developed when the cars were still under warrenty.
