New rims+ coilovers =rubbing...any suggestions?

mhamouda · 07-18-2013, 08:23 PM

I recently installed my coilovers and its rubbing a lot from the rear tires when I have 1 + passenger in the car, ex (go over a plaza pavement or go underground between p1 and p2)

Here are the specs of the setup:

2000 540i
ST coilovers lowered all the way (5 threads left from the bottom)
Rondells 21- 18x10 et 18
Tires are 265/35/18 pirellis

Rear bottom end suspensions are stock (control arms and sway bars)

Here are pictures of the car before and after lowering it and the gap I have between the tires/ fenders

Is the tires setup ok for the car or should I go thinner?
Will rolling the fenders be enuff to get rid of the rubbing even with 2 passengers in the back?

Thank u

Do you know where it's rubbing? Outside edge of the tire on the fender? Or somewhere else?

since this is the first step to troubleshoot -
i rolled the fenders yesterday using the eastwood roller -

the rubbing is alot less, but it still rubs in certain areas.

i didnt think the setup is gonna be that hard to fit considering the width of the rim and the tire size for a 5 series

It's your suspension. Too soft.

At this point, roll the fenders as much as you can and dial in some more negative camber.

I wish I got to this thread sooner before you rolled. Anyway, I run coilovers on the absolute lowest setting (with some tire tucking) with 265's in the back and it's no longer rubbing. I've fought this issue for a while and had my fenders rolled. While that helped, it lead to bigger problems in the wrong run.

The problem with rolling your fenders is that the whole lip of your fender is painted. When you roll the fender, it cracks the paint. The problem with that is after a while, water gets in there and you'll end up with rust on your fenders.

90% of the time, the fender isn't as much of the issue as is your bumper clips in the back. If fenders are indeed the issue, the best way to deal with it would be to get your fenders shaved entirely on the inside and repainted. This is all just my humble opinion though.

I would definitely take a close look at those bumper clips. They're located where the bumper meets the rear fender, they stick in quite a bit. I am willing to bet that if you haven't touched them at all in the past, that they're rubbing like crazy.

I've had rolled fenders on three cars. Never cracked any paint. The key is to heat the metal and paint before rolling. Works flawlessly every time.

and even if you do crack the paint, its on the inside of the fender. just paint it. no one will see it anyway.

Problem 90% solved...very minor rubbing now.
Fenders were rolled all the way in but that didn't solve the issue so we just cambered the back wheels in a bit on stock parts.

This seems to be more of an e46 issue since e39 don't have the same bumper clips
