Warranty: BMW replaces free of charge 1M front fender liners (rubbing issue)

[mattm]

And I was thinking the Hoosiers ground that away like sand paper.

Yep, that is what mine look like.

Then I guess its safe to say its not a new part but rather a different mounting position. Hopefully we can figure this out before my wheels come in and I have to cut to fit.

Affirmative: different design of the middle three fins/notches + indent is OEM. Below some pictures (June 2011 build). Small black triangles at the bottom of some fins/notches: tell-tale signs of the "love story" between front tires and fender liners...

Actually, so far no clarity about that. Anyway, as for now, the heat gun might be your 1M's clearance friend (but do handle with care). At least resolved the clearance issue on mine.

Below two pictures posted on the German 1M forum (the second picture is of an early 2012 build 1M). Do you see any difference in design and/or mounting ?

They all look the same to me, do you see a difference??

Anyone in the US have this change made?

I am noticing a rub when turning to the left (mostly when backing up) in the front right fender. I have not noticed the left front fender rubbing. Not only is this annoying (least of my concerns) but I don't want to mess up the fender liner or the tire!

As quoted above, a German 1M owner reported (Apr 14, 2012) that his 1M front fender liners were replaced upon initiative of his dealership (he visited his dealership for another reason and they spontaneously raised the topic themselves):

"I visited my dealer for another reason.
There I was informed, without [my] request, that the front fender liners must be replaced. Info from BMW. Upon query for the reason [of the replacement] the answer was something along the lines of «rubbing of the front wheels against the fender liners at full lock during reverse driving»".
("Ich war wegen einer anderen Geschichte bei meinem [dealer].
Da wurde mir ohne Nachfragen mitgeteilt, dass die vorderen Radhausschalen getauscht werden sollen. Info von BMW. Auf Nachfrage warum war die Antwort war in etwa.....Schleifen der Vorderräder an der Radhausschale mit eingeschlagenen Rädern beim rückwärts fahren.")

So if you experienced/noticed fender liner rubbing (check especially the front right), then keep your ears and eyes open during your next 1M service visit to the dealership. It might be that they raise the issue before you do.

Here's a take on the issue, via two pictures of stock 1M wheels and tires, by a Belgian bimmer forum member (Andra): the "indent zone" of the fender liner should be sitting a little lower, more particularly in the tire versus fender liner "contact zone" (source: http://www.bimmerboard.be/forum/inde...opic=26797.315). Seems to make sense IMHO.



Furthermore, he correctly pointed out that rubbing tires can be a reason to fail a pass at the motor vehicle inspection in Belgium.

Maybe this is BMW's way of telling us that we must lower our cars. We need to make the touch zone fall into the indent after all.


BTW, can we post pictures while using the app?

Actually, it could make sense what you jokingly commented: it ain't excluded that the 1M was sitting a little lower in the fenders during development (no contact tire versus fender line due to compliant indent height), but suspension was fine-tuned a little higher in the final stages of the 1M development (more ground clearance). Fast development, as we all know. Consequence: rubbing due to a lower sitting "contact zone" ("indent zone" located a little too high) = compliance issue.

Aproved by the BMW inspector and gettin mine mounted may 25th.

The improved ones have a different mounting system.

Mine is lowered(HR sport) and no rubbing, but very little clearance!

Thanks in advance for checking also the following during the replacement:

Any change in part numbers ?

• front left = part# 51 71 8 051 591
• front right = part# 51 71 8 051 592

Any change in shape or its mounting holes (see picture below) (note the indications "E82M L" and "E82M R"):

I had my front liners changed today under warranty.
The parts have the same code but no changes in the moulding form or mountings.
So bottomline much a do for nothing.

But I have some other serious probs. The upper and back liners at the front wheels showed some major holes due to wheelrubbing. I think this could be related to tracktime @ Spa. I've noticed a hole in the left wheel liner whereas there was none on the right side and Spa track has more right curvers/corners.

Pic below shows rubbing and bare metal

Many thanks for the update, gs! I thought about you yesterday because you had mentioned the date of the replacement works.

Quite worrying to see the merciless impact on the fender. Also does not seem healthy for the tires longevity.

Have you noticed the reference on the sticker: "Achtung! E-82 M.Pyrat" ? Perfect idea for a decal on the outside of, for example, EINSER M.

mort de rire Artemis!
i added NITTO tires as sponsor on the car and working on one more from DPE wheels USA. soon soon soon i hope!

[Papethova]

Be careful, tire rubbing could lead to tire failure. I was in a car on the track with serious tire rubbing and we had no idea.

One lap after I got out the tire blew (120mph+) and the car slammed into the outside wall of a large banked curve , driver almost saved it.

So no corrective action, just free replacements throughout the warranty period!?
