30% bengkok!!!! Any cracks on the wheel? Maybe it's time to upgrade your wheels. I think I read the is someone selling M Parallels on the forum.
BMW memang lower on the driver side. Much has been discussed about this in the forum. Make a search & you will find quite a bit of discussions about this issue. Any idea how much is the difference? You can measure it by parking on a level ground. Use a measuring tape and check the height from ground to the front bumper lip. Then that's the difference.
If this difference bothers you and you must have it corrected, please send me a PM and I can share with you some metihods to correct it.
