Hi,

Any recommended shops for front fender rolling in the San Francisco Bay Area?

Thanks

jangy

Make sure you honestly want it before you do it. Also, make sure they use the little hand held rolling tool and heat. Most good wheel places can do it.

tbone

Yeah, I need it...I'm rubbing when I turn into driveways.

there's absolutely no reason you should have problems with 19" 245's. i've got a buddy with a lowered e500 running 20" 255's with no rubbing. i would SERIOUSLY consider setting your rims up with the proper offset before rolling the fenders!

Jrocket

I agree.

There seems to be a common theme...so let me ask, what are the drawbacks of rolling my fender?

My front offset is aggressive, but I think it's correct. I ordered my rims through Wheelexperts. I don't rub with daily driving (right turns, left turns, U-turns, etc.) I only rub upon compression if I'm turning right ONTO a driveway. To avoid rubbing, I need to do a full-lock turn into the driveway.

I appreciate your help!

jangy

If the offsets are right, then you need to look at the overall diameter. 245s should not rub, regardless of the wheel diameter. I would NOT roll fenders, yet.

On your car, rolling fenders is not as simple as on the E55s. The E55 already has the lip curled under, so you aren't making any new crease if you roll them. On your car, that is not the case. They have a little lip on the inside and that is it. If you roll, you MUST make sure to fold that lip all around at the perfect edge or else it will look funny or even split the metal.

I'm running 275s in the front and 295s in the rear with no rolling at all.

Am I running the right-sized rim (8.5") and offset (+28)?

If so, what could be the cause of my rubbing?

jangy

That offset is way too aggressive. You need the wheels tucked in a bit more. Consider shaving some of inner wheel (~4mm). Make sure from the manufacturer that you can.

Be careful, because rolling your fenders will likely not fix that. What is going on is your entire tire top is coming out of the fender and then you hit a bump that compresses that fender onto the TOP of the tire. A little rolling will do nothing. You have to either change offsets, or go with a smaller diameter tire.

tbone

Thanks for the explanation. Follow-up question. I recently lowered my car a bit more (~1/4-1/2"). Prior to lowering the car, I did not have the rubbing issue when entering my driveway. Would re-raising the car be the better solution?

jangy

It would fix it, but it may not be the best solution. To me, the best solution is to redo the offsets.

OzE55

The cheapest solution is to push the raise suspension button when entering driveways at low speed - wont rub then!

tbone

True, which is what I've been doing, but just not as fun

I have done a lot of research on the boards about offsets and rim and tire sizes and have seen that there is no right offset, just preferred, aggressive, etc. I have also seen some offsets that some say should never have worked but seem to function just fine on the owner's car.

So I am confused as I too am now having a tire rubbing problem with my new wheels.

I am running Falken tires on:
20x9 w/ 245/30-20 [+32]
20x10 w/ 285/25-20 [+37]

I also have a Renntech ELM on 3 front; 6 back.

Immediately after the install i drove around at moderate speed (30-35mph) and noticed rubbing on the rear when I turned with the body roll and also on the front when turning into driveways.

I have had numerous cars lowered with aftermarket wheels and this is the first I am experiencing the need to tailor my driving because of my wheels. Is this right??

Oh yeah, the shop I got the wheels from rolled the rear fenders due to the rubbing, but I have not yet had the opportunity to test drive again.

Any help with this is greatly appreciated.

Thanks in advance!

jangy

You are right, there is a bunch of hearsay, etc. on the right fitment for a W211. You just have to sift through it all and decide what stories to belive and why. Keep in mind that most people buy the rims that the manufacturer offers and consider that to be "MAX". Others actually play with the various configurations (like me) and build a database of what worked and what didn't. Unfortunately, I have not done that with 20s, but i think I can shed some light on what is going on.

Fronts:
You increased the overall diameter by 0.28% (minimal), BUT you also went more aggressive with the offset. What this will do is have more of the top of the tire exposed on turns than OEM. If you hit a bump while turning the wheel, your fender could rub on the TOP of the tire. Fender rolling alone will not end this. With that skinny of a tire, I would tuck them in a bit more.

Rears:
You increased the overall diameter by 1.21% (minimal) and the width by 7.55%. In this case, you went with an inch wider rim, but dropped the et to 37. You effectively ran a more agressive setup. Again, I would suggest more tuck. BUT, if the roll works and you are happy, I say leave it. You are really on the cusp of rubbing with et37. A few more mms and you will be in safe land.

Thanks Jangy.

Do you think +34 on the front would alleviate the rub on the turns?

chiromikey

add 3mm more to your offsets and you'll be perfect. 35f/40r with 255/35/19 and 285/30/19 works PERFECT on my lowered e55.

Whats up Jangy??

Just thought I would clear up one thing. The E500 and the E55 have the same body panels. The AMG has not more fender rolling than the normal run of the mill E320/E350/E500/E550. Since the E500 AMG sport came with the same sized wheels the body is the same through out the model line.

But in this case the best solution would be to change the wheel off-set since I have never really seen a front fender get rolled at all and not have the paint crack. My C32 cracked when I rolled it 100% flush with the body in the front. The rear fenders roll far better without cracking the paint. I even rolled the part of the fender that is up by the door jam and it did not crack at all (and we were wailing at the body like red necks drinking beer!

WIS says to use a heat gun and a rubber mallet to roll fenders on the R230 (when using 19 inch wheels) and I have heard that the roller actually cracks paint worse than a mallet.

How is the E55? Mine is sold and gone. I do miss that engine as it was an amazing motor. I don't miss some things but for a fast 4 door the E55 was a fun car.

Any new tweeks to yours?

We are running almost identical setups. I'm on Falken FK452 with 245/30/20 and 285/25/20. My wheels are Radenergie R10s, 20x9 [ET:34] and 20x10 [ET:31]. I'm lowered on RLM as well. With this setup I'm fine in the front but rubbing in the rear. The rear fenders have already been rolled so my rear wheels are off and getting 3mm shaved. I'm hoping that an offset of 34mm will alleviate the problem.

mprsev

So do I need to send the wheels back or can they shave down the pad? What to do?

mprsev

Do your front tires rub when turning into driveways, dips, etc? I really want to see if shaving 2-3mm can make the world of difference. I can see that I have a lot of brake clearance, but not sure on the inside well.

This is frustrating.

vegastrashed

I have zero rubbing in the front. All my rubbing issues are in the rear. I wish that the R10s I got didn't have such an aggressive offset. I'm going though the same ordeal again with the E63 that I did with my previous 545i.

jangy

I think so. i would have picked 35, so you are close.

jangy

What up bro!?!?

I am going on a ride from San Diego to Palm Springs and back with a bunch of exotics this saturday, so i will wash the car and slip on the HREs. Not much done to the car. we have some plans. I am probably going with a bunch of custom stuff to save money and have fun doing the playing. The car is already fast, but i still want to play with the suspension. Still hope to get a track car. Hope this thing lasts until then.

jangy

You can typically take 4mm from the inside of a forged rim, especially one with aggressive offsets, but check with the maker.
