So I got HR sports springs installed this weekend, and I have some rubbing in the rear. 220m wheels: 19x9.5 et 23 rear. 275/30/19 sumitomo htr zIII. Already rolled the fenders. -2.7 rear camber

I don't think going down to 265/30/19 will get rid of the rubbing, and I don't want to put on 255s because I don't want to put 225s in the front.

It rubs where the fender meets the bumper. Rubbing on the fender and the bumper... Any suggestions?

Thanks to Dave (dave96dcm) for all of his help! Fender roll, springs installation, alignment.

If there's a machine shop in your city you might see if they can "SAFELY" machine 5mm off the mounting surface of the wheel without compromising strength. I know for a fact my 19" AluFelgen wheels use the same casting for ET30 and ET35, one is just milled/machined more. It's a long shot and I did capitalize SAFELY...

you have to shave off some bumper and fender and carpet liner where they meet up on the inside. robc1978 made a thread on this subject.

[Delusive]

What the two said up there or get a little more negative camber in the rear if possible.

I never had wheels machined before so I'm not sure about that one. I'll probably do some research and see if anyone is having any problems. I feel like it'll compromise strength, but like I said I have no idea. Worth a shot though.

I'm trying to find a body shop that's willing to shave the fenders and the bumper but so far every body shop I've been to said no. Maybe I can do it myself.

I found one place that does custom body work:

I'm going to stop by today to see if they can help.

Correct me if I'm wrong, but I think -3.2 is the max camber I can get. Need to get that done, definitely.

Thanks guys, I appreciate all the help!

I wouldn't recommend shaving anything from wheels. It can be done, but depending on the wheel it might be very small amount that can be shaved like 2-3mm. Max stock camber at rear is about -3.

This is the thread #Tee was talking about. http://www.e90post.com/forums/showthread.php?t=814434

Great looking car and nice wheel setup. By the way it might also help if you go with 265/30/19.

Thanks for the link man. I don't think shaving the fenders will help. The tires extend further then the bumper and the fender, so making the fenders thinner won't work. I may be able to pull the fender out a little, but I don't think I can pull the bumper out. Since the bumper is plastic I'm guessing it'll just go back to it's place once I stop pushing/pulling it out.

Looks like my only hope is more camber and 265s or 255s.

Let me know if I'm wrong with my assumptions, this is my first bmw so I'm not very experienced.

I'm a machinist. I could cut anything you want off those. I have 220m on my e92, not lowered, on 265, and it doesn't rub. I was going to remove some material if mine didn't fit but they did. There is plenty of stock on the back of those 23 offset to cut safely

You should also consider that even if the wheel's back pad has enough material to safely be machined down 5mm, the lug holes have already been drilled. You would thereby increase the number of threads that you're allowing to pass into the hub, which poses other issues.

Mine is like this and it rubs only slightly to that fender bumper bracket.

I wouldn't recommend pulling the fenders, like you said it will look stupid, because the bumper wont be flush with fender anymore. Yeah, narrower tyre probably is good choice. Try to add max negative camber and 265/30, then maybe cut the piece of that bracket away.

Your 19x9.5 et23 is the same as 9.5 et15 on pre-lci. I know you don't want to go with 255/30/19, because then you need to change the front to 225/35/19. If you go with that setup i would add 10mm spacer to front.

Here is pre-lci E91 with 9.5 et16 and 255/30 rolled fenders and no rubbing.

on a serious note tho the easiest way would be to go down in tire sizes, if the rims are staggered there is no reason why you need to go two sizes down. Go to 255s on the rear and 235/245s on the front.

I just don't want to risk anything. I'm going to skip on cutting the wheels.

Yeah, I just realized I could have thought of a better title I have an xi so I can't put 235s or 245s because of the rolling difference.

Thanks for the pictures man! Since I'm at -2.7 camber, I can only get another -.3. Do you think -.3 camber will provide any clearance? It's such a small number, I'm not sure if it'll do anything. I don't want to buy 265s, and then buy 225s and 255s because it still rubs. I think -.3 camber will provide like 1mm of clearance.

[///M3NACE]

You're thinking too much. I would def do 265 30 19 on the rears. I know discount tire will return the tires for free before 30 days. Go with something the stretches like the falken.

My setup used to be
20x10 w/ 285/30/20 with falken I forgot which tire.

I rolled my fenders and would barely rub with 5 passengers. No camber. All meat.
You have an LCI so it will be different.

I think do the camber first, then shave as much as you can, then decide between 265 or 225/255.

Yes, definitely. I need to change the front springs anyway, I don't like the reverse rake. I'll get the camber out of the way at the same time. Maybe the camber will be enough anyway. Thanks guys! I will post pictures with updates!

+1 falken. I have 452s. They run smaller width wise.

Actually, if you compare the specs, sumitomo htr z3s run smaller than falkens.

sumitomo: 10.2 section width
falken: 10.6 section width

I've decided to put my winters on to get rid of the rubbing. When it's time to put summers back on, I'll increase the negative camber and hopefully I can save enough money to buy kw v1s. I think if I raise the rear a little bit, I can get rid of the rubbing.

Thanks for all the help guys!

Most likely not that much. Like you said so small difference. They added about -0.5 camber to my car when i did alignment, but it didn't really do anything. Then again it doesn't hurt to try.

[VTECaddict]

Set it to ZERO toe in the rear with max camber. That will give you a little bit more space than just camber alone. Mine max'd at -2.8 with 0 rear toe.

0 toe already, with -2.7 camber. Dave (dave96dcm) did my alignment and spring install, and he said max I can do is -2.9. I'm not sure how that's calculated, but I guess the number changes depending on the springs and the tires?

This is going to sound ridiculous and I'm not gonna advise anyone to do the same if they have rubbing issues, but I got so pissed about the rubbing that I stopped slowing down for bumps. I'm not speeding or anything, but if the speed limit is 40, I drive over the bumps going 40 if it looks like I won't bottom out or scrape. Believe it or not the rubbing decreased incredibly So far it only rubs on highway speeds. No cracks or bends and everything seems the same on the outside. I need to take the tires out and check what changed.

You might be rubbing liner... And now just have worn that spot down enough to make it clear.
