Sorry if this bug has been mentioned before, this one thing is bugging me, when you change the camber in any car. the wheel povit at the bottom of tyre instead of axle...

wheel moves in and out of the arch but the track at the bottom of tyres are remain same...

I think you have the definition of track mixed up. Track is defined as the distance between the midpoints of the contact patches on the left and right sides of the car. Thus, when the wheel pivots due to dynamic camber or due to a camber setting, the track is affected because the ground is not the pivot point for camber.

Camber roll, on the other hand, is the angle of the wheel relative to the perpendicular of the road, but that's not really relevant to this discussion.

This is all made very clear in the suspension diagram in LFS, particularly with double wishbone suspension.

TRACK: Distance between the centers of the tires where they contact the ground.

The LFS Wiki also mentions it but oversimplifies the definition as being merely the distance between the wheels, most likely due to the much simpler suspension back in S1. This is probably what threw you off. See here:

uh erm i think i explained it wrong...

here is the pictures.. which i hope i help u understand.

I am sure you cant widen or narrowen the suspesion arms on average standard gti's. It would be LOTS of work.

Jay

makes perfect since, your only changing that negative to a positive, there shouldnt be any affect on the patch then (distance from car wise may change, but either way the same amount is touching the ground either way)

Ah, I see. I'm sorry, I didn't read your post carefully enough. Yes, you are right, with trailing arm suspension, the camber pivot is the ground. I'm not so sure this behavior is incorrect for this suspension type. The others (MacPherson and double wishbone) behave as I would expect.
