No squirming in the rear . I'd say the rear cradle can move around about 1/4 inch . The lock out kit keeps it square . But on the street the rubber is still there to absorb the vibrations .
It's pretty easy to install . The worst part is getting the limiting plate off the front of the cradle . But do as the instructions say and drill it ( I used a small bit to make a pilot hole then went with the bigger bit ) . Once you split it , it will pry right off . The rest is pretty straight forward .
You could always wait till challenger fest and I will do it for you right in the paring lot !
