The e90 has a MacPherson strut style front suspension. The nature of this type is to gain positive camber through part of the wheel's travel. Below is an extreme example of this. Notice the loaded wheel (front passenger) has the top angled outward.
Below is what you want to see. The wheel is perfectly perpindicular to the ground at the point of greatest weight transfer.
If you don't adjust for this, you end up rolling over onto the outside of your tires, and minimizing your contact patch. Since chassis balance is all about grip, a small contact patch means lower grip. Lower front end grip means more understeer. This is especially important for our cars (x-drive).
One of the easiest ways to fix this issue of dynamic positive camber gain, is to have a fairly large amount of static negative camber. This way, as the car loads up the front outside wheel, the wheel naturally drifts into it's optimum contact patch.
Hopefully, that makes sense! |
sweeeeeeeeeet visuals! so doesn't that create more wear on the outer tread of the tires during normal driving?
