no it's rubs because your camber is not negative enough....just roll your fenders it will make a difference:thumbup:

I have to ask... How would moving the inner edge of the tire TOWARDS the surface it's rubbing reduce the amount of rubbing? :dunno:
yea!

nick, it depends where the point of contact is. Usually when we talk about rubbing, it means that the outer edge of the top of the wheel is getting into the inner edge of the wheel well, the fender. the wheel well inside has more space that is concealed by the fender which closes over the wheel well. using more negative camber moves the outer edge of the wheel away from the fender and into that extra space that is in the wheel well.

If you are rubbing on the inside of the wheel well, your suspension setup if fuc*ed. That means you are running out of travel or you wheels are truly too wide. But with 255s that is not the case. some people are running 265 with no problem. Do a search on the forum if u don't believe me. It also depends on your offset though.

sorry I didn't reply, was not subscribed to thread since I used the quick reply at the bottom of the screen =)

I don't know potpie, I can't understand clearly where it is rubbing. So is it rubbing on the inside or outside? Anyways, if it is on the inside, I would feel it is a suspension problem. Are your shocks in ok shape? What about the bushings? Has there always been rubbing with this width tire, or only lately? I think wheel offset might play a role in this too. If you could supply more details I might be able to help more.

maybe take a picture of the wheel and where it rubs?

ok its 255/35/zr18 and its rubbing on the inside...how would i know if my shocks and bushings are ok? they feel alright i guess, where would i look?

and i dont have a picture right now but i think its from the negative camber, on the left side of the car, the right side of the tire rubs on the inside....i think my car is too low?

in that case, a camber plate would still help... one problem with lowering your car is that the camber can become incorrect since the suspension is not tuned to be so low. So you can dial in more positive camber. I truly think this would help your rubbing problems, since its only rubbing on the inner edge of the tire, correct? Not on the top as well?

Its hard to tell whether the shocks and bushings are gone, without taking a closer look and basically taking them apart. But you should be able to feel a ride difference. But from what you've told me now it seems that they're alright. Just get camber adjustable bushings for the rear and increase the camber, but still trying to keep it negative. It's only on the rear, yes?

And potpie, is that really you in the family pic? That's not current, right?

hahaa, no wonder!

Anyways, yes, the camber should be a little bit negative... So it still rubbed after the alignment? That's strange... did you get it aligned at a dealer? perhaps he was not aware of the proper alignment dimensions.... take a look here... http://www.my330i.com/alignment.php

if a dealer alignment doesn't work, request the readouts and go to a specialist... I think that more positive camber might work, but if not, castor adjustment might be needed as well. If that doesn't work, well.... raise the car back up and lose the drop! =(

no, not neccesarily. Some drops are just too drastic. Still, I think it can be remedied. flaring wont work because you're rubbing on the inside, so I believe increasing the camber is the key.

Is the rubbing on the whole of the top inside of the tire, or only the part of the tire closest to the front of the car? That would indicate too much toe in.

no its not that low at all... very weird.. esp with the BMW rims which are correct offset and all.... very strange...

What would make you think its rubbing? Describe the symptops, Ie, is there a rubbing sound all the time when you drive, or only when you have passengers or something else?

ah, potpie, that is really not a problem then. That's something you'll have to live with, it's not really rubbing in my opnion unless it happens frequently. What would prevent it from happening even in those circumstances you described, is getting better shocks, IMHO. some adjustable ones, which you can make harder, so you can adjust just up to that point where the hardness is still comfy but not causing rubbing to occur when the shock is under load. Try it... but I know its expensive =(

I'm running Eibach prokit, had 4 people in the car, and no rubbing, but then again, I'm not running 255 either, just 245.
