HI everyone, I have a 2002 330Ci with a rear wheel problem. Since my tires are 255/30r18's in the rear, when I hit a bump or rough patch in the road my tires will tend to rub the fender lip. This is vary trouble some since it will ruin my new tires. I was told from the dealership to either get the fenders rolled, which might chip the paint and cost more then I originally planned to spend, this option doesn't guarntee it won't rub again. Or raise the back end up a half an inch so I can put full load on the rear end and not rub. What do you guys recommend or if there is another option besides changing the tires please let me know, I have to get this done soon, leaving for a west coast road trip in June.
