Long Tracking 01 Mxz 700

I am thinking of long tracking my 01 MXZ 700. I was just wondering if any one has any tips or experience doing this. I am considering a Tracks USA 136" rail extension, and tunnel extension and am going with a 1.5" Ripsaw track. I am also wondering do I need a different rear bumper and trim pieces for the sides of the tunnel. Also is the ride the same as a factory long track, cause I believe the suspension mounting points on a factory long track are in different spots.

please give me sum feedback, Am I crazy to want to do this?????
