My car has negative camber in the rear. Why is this?

I think it's photoshop.

;-p

But perhaps your diff mount is weak also. You might try replacing it.

Cheers,

Are you asking why from an engineering or technical perspective?

I believe the negative camber is accentuated by design as the suspension geometry of the 2002 is loaded to increase the contact patch and increase the sure footed handling while accelerating out of the turns.

This is common in most performance vehicles with semi-trailing arm suspensions. When the ride height is lowered with sport springs, the static negative camber increases undesirably.

To counteract this effect I installed the Dinan rear camber adjustment kit on my rear axle. Inner tire wear can get rather bad and with staggered directional radials, too much camber becomes expensive with respect to tires.

Initially my drop caused the rear camber to increase to -2.5 and -3.0 degrees respectively on the L & R sides. I cranked the eccentric adjusters to drive the total camber back to -1.5 on each side.

Not sure if this answers your question?

yeah I appriciate the answer, but I have stock suspension accept my my shocks looked newer when i bought the car. I don't know if 2002's came with negative camber from the factory, so I don't know if this is normal, which is why i'm asking. I was wondering if it was a problem:dunno ( besides the fact that it wears my tread down )

i highly doubt that a car from the 70's or even any car comes with negative camber from the factory.

Oh contrare MFever, according to the factory service manual that I just referenced, the recommended camber (with normal load) is -2 degrees +/- 30 minutes.

As stated previously the production vehicle did not provide a means for adjusting camber and this value will increase significantly when the suspension sags or you lower the ride height.

Obviously installing wider tires will also exaggerate the inner tire wear.

Check out all the bushings in the rear as the rear trailing arm bushings are most likely well beyond their service life.

All BMWs came factory with negative camber in the rear, and still do
