I agree with the above post about defeating the mobility of a mid rise lift by installing it in a pit. But on the other side of the coin, most modified cars that an enthusiast would put on a lift are too low to roll over a mid rise lift.
I know for all my regular cars, driving over a mid rise is easy, but for my pride & joy Mustangs, I run into all sorts of issues with longtube headers and torque arm rear suspensions. Adding planks of wood as a ramp can fix the problem, but they take up a lot of floor space.
