vbp tubular A-arms
I'm going to change back to Original height springs. When going through things, my eye fell on the pointy bumper stop under the,upper A-arms. As I use the vbp tubular A-arms that are different in that area (Original A-arms have a different shape and have a dimple where the bumper sits) I was wondering if the tubular A-arms would pull the suspension up causing a higher ride height than normal ?

Well that is just it, if the upper control arm sit more deeply over the fullcrum of that bumper stop, and the spindle would move lower, which make the spring push the frame up, right ? Or am I seeing this wrong ?

The upper a-arm just swings on the bushings. It doesn't exert an up/down force.It only locates the spindle in a fore-aft (caster) and in-out (camber) plane.
I don't understand what you mean by the bumper stop being a fulcrum? The bumper stop does nothing until the suspension is in full droop, at which point it prevents further droop. At any other time there is no contact between the stop and the a-arm.
