This is the All New Long Arm Conversion for your Gizmo Genesis and GZ2 Kit (for GZ2, you must get angled ball ends for rear toe link).  

The new longer arms have been designed to use in combination with the V2 Uprights.  Contrary to typical longer arms, these arms actually make the suspension act softer as the distance between lower shock mounts and outer arm pivot has been increased.  The pivot of the uprights has been moved out further which in the front end allows for less wheel scrub as well as more wheel support.  The result is a more precise car, with more stability and higher corner speeds.
