I have lowered my Z3 3.0 by 30mm. It would seem the best thing to do is allow a few weeks for the car to settle then have the tracking/camber checked with a laser align. I'll definately have the tracking checked but there is no camber adjustment front or rear, so is there any point in having a full laser align?

I know there are camber adjustment kits available but is it needed with a 30mm drop? :-?

probobly not with only lowering springs as they dont change a great amount, but for the sake of having it done while the car is in the garage you might aswell spend the extra £30 or so to get some peace of mind.

BMW do a camber correction bolt for the front which is basically a special bolt that allows the hub to be pivoted out more but that only allows 1-2 degrees movement I think. Item 5 in this link;

The main concern will be the rear as it is not designed for adjustment unless you go for one of the correction kits which entails welding plates on the rear trailing arm pickup points.

I thought as much. If I were going lower than 30mm I would probably do something about it, cheers for the advice guys.

Now I can :coolsteer) my :coolsteer) and won't :-s at every corner.
