One caution though - I am using laser interceptors. My 9500ci came with ZR4s but they don't have enough range to cover the whole front section from the mounting position in this pic. The best position if you use ZR4s is in the edges of the upper grille next to the headlights. The alternative is the LIs which are invincible even from the mounting position shown.
I can tell you the vast majority of people who install shifters, no matter what brand they buy, botch the installation and get very little protection from them.
