Point 1 from my earlier post explained:
Suspension-mount: The place on the car's body where you fasten the top end of the strut/shock (the place at the bottom is also a suspension mount but is not generally referred to as such - normally). If you open the hood you'll see the top of the strut with 3-4 screws holding it in place. That "place" is called the suspension mount. Its a solid enough structure in the frame so that it can withstand the suspension load without deforming - much.
Movement of Suspension Mounts: Since these mounts are an integral part of the overall vehicle body, that is, they r attached to it and the body is not rigid (It can bend/flex under force) these mounts can move as well and loose their original location (deform under load). As soon as the load is taken away they'll regain their location. plz note that its not a large movement, only a slight movement - mostly not visible to naked eye but enough to change the suspension-geometry.
Camber Angle: (I don't have a picture handy so you'll have to work with me). An angle formed between the vertical axis of the wheel (WHEEL/RIM not tire) and the vertical angle of the car. If you look from the front, and the top of the wheel points out it is called positive angle. If the bottom of the wheel points out it is called negative camber.
Camber angle affects the handling of the car. e.g: negative camber helps in cornering since the tire remains flat. (we can discuss this more)
for max straight line acceleration ideal camber angle is zero - but then you want to go in a straight line only and not turn!!!
Load on tire: when you turn ur vehicle you place a load on the tire - a force (class 7 physics - remember Force?)
So coming back to my statement: When you load your car's tire, it changes the camber angle. Lets say that the load is large enough (e.g: when you are taking a turn at higher speeds) it'll roll the car's body. Before the car body roles, it will flex - The car's body is not a rigid structure and it has some flexibility. The suspension mount itself will not move but it'll flex at the place where it is attached to the frame/body. This will change the Camber angle (since the car's body vertical axis has now changed). Since the camber angle has changed, the tire's grip is reduced (contact patch area is now smaller). Since we don't want to loose grip, we need the suspension mount to stay in its original state. To do that, we transfer the force to a "solid" place. To do that we place a strut tower between the suspension mount and the solid place.
When we place the suspension mount between the two suspension mounts - then we transfer the load from one wheel to the other. This is ideal in my opinion but I can explain it in a latter discussion when you have this one down.
I hope it is somewhat clear to you now. Let me know if you still want to know more.

P.S: Read it 2-3 times and i'm sure u can get it.
