We used to have to do a lot of altering in the vehicle to install the brake Remove insulation under carpet for brake travel, drill holes in floor to mount. That has been eliminated because of the brake being mounted to the front seat bolts, better positioning for each instructor, and cable is much thicker for better durability when needed most. Makes uninstalling much easier also to move to next vehicle. We have the brake in our Toyota Rav4's and bZ4X
