ok,,, this may become a bit contraversal but still here goes
i prefer to jack them up under the correct jacking point, under the floor cross-member... but a decent sized piece of wood or rubber is needed if you don`t want the floor to buckle
if your floor is rusty,,, then forget it
now,,, in saying all that, & """IF""" your floor isn`t rusty, then ---> the floor cross-member has 2x "down" pieces (if you get my drift) it`s a box & we want to jack up under the vertical pieces of that box
it`s under one of these (or both if you can spread the load) is where you want to lift at & it will lift the whole side of the car really well balanced
if you have a hoist then i suggest right at the very front of the floor,,, & again,,, under the "Down/vertical" panel at the inner guard , there is a very short flat section in-front of the foot-well but at the bottom of the rear-part of the inner guard
at the rear... it`s a case of under the subframe channels or under the little metal "Tabs" (body alignment tabs), or at the very rear-most part of the floor just infront of the subframe mounting point
ok now,,, go on,,, fire away
