Cornering problem

I have 2 Q and hope you quys can help:

1.A month ago I mounted a new M suspension and M-135(all from a new 330i Clubsport ) and after a week I started notice problems when doing a right corner. The car sways more and when going fast(not much) the car is going up and down in a vertical way ( like the wheel is losing and geting grip, but not like ASC ). Since the suspension is new and so are the swaybars and the alligment is OK I dont know what to do. Is it possible that a bushing of the swaybar is broken? Also when I drive slow on a bad road the rear is swaying...

Problem 2:
Also I noticed that the front wheels are ( when slow parking in reverse or at driving uphill-at the top of it ) having like a small "losing"-like real small right-left losing. Maybe just because I changed the original 15-inch to M-135 and all is more direct or i could be the "bumerang"or what ?


Thanks in advance

For #1: You did get a new alignment done, right?

For #2: Please explain again, I'm not sure what you mean.

1.Yes i did, and it was like ok for a week, then it started.

2. Ok , i will try: you ride uphill and when you arrive at the top the front wheels are for a moment like "bobleing" right and left ( mind that the steer. wheel is not moving, but you can feel wheels like moving )... sorry, but its hard to explaine in english..

Is it that you feel like the wheels are moving or do you actually hear noises, maybe like some clunking coming from the front? I would check the sway links first. Make sure they are torqued correctly. The shifting or having some play could be control arm issues... Sorry... I hope some of this information helps.

No noises, just a slight felling on the steering wheel like something is loose. What you think with torqued corectly ? ... btw. thanks for help.

Well, with all the different changes you made, this is going to be a tough one to figure out. What size are the M-135 wheels? 17, 18? Jumping up that much from a 15" wheel will make the car perform very different. You are going to experience more tramlining, as you have a bigger contact patch on the road, so the tires will follow the imperfections on the road. Have you balanced your tires, or at least try and rotate them? This is a stupid question, but are you sure your lug nuts are torqued correctly?

18 (225 front, 255 rear). You think that the nuts are loose?-that will be too easy for a solution ( Murphy ) anyway i will check..

Its the second problem that puzzles me most /since is the danger one /...i know:go visit local BMW...the problem is that they charge like a PRO and that the knowledge they posses is rather, khmmm, lacking to say the least.
