Channelling Lowrider.
Channeling (also know these days as a 'body drop') is a fairly radical but very effective way of car styling to get your vehicle lower to the ground and 'in the weeds' as it were, without performing suspension modifications. The process in theory is pretty simple but in practice is much more difficult to carry out. Older cars like a Model A are much easier to perform this on as opposed to a later, full-fendered car.

Basically it involves cutting the body loose from the floor, dropping the body by the desired amount, then re-welding the body back to the floor. depending on the chosen amount to be dropped, this can also have a dramatic effect on the the interior space as whatever amount is lowered over the floor is obviously lost in the interior height. If choosing to roof chop the vehicle then this space is reduced even more.
