Need help with rubbing issues... Continued

Hey Guys,

I'm honestly desperate at this point for help. To try and sum everything up, I have had a set of MRR wheels manufactured to my heavily researched conclusions which are 9.5 et22 (235/35/r19) front, and 10.5 et22 (255/35/r19) rear. The tires I chose are Hankook Ventus V12. I came up with these offsets from looking over the "stance threads," along with the recommendations of one particular wheel vendor. (left undisclosed)

Car in question:



I have had my rear quarters heavily rolled along with the car aligned. My toe settings are in spec, and I have the camber specs at -2.7 rear on both sides. From my understanding I should not have any issues fitting these wheels on my e92 chassis, but my car is rubbing like I have never seen before, even at the hardest dampening setting. I have verified that the wheels themselves are in fact the correct offsets. I am running KW V2's and I am still at a conservative height as far as i am concerned. The top of my tires are just barely hidden by the bottom of my fenders/quarters. What my questions are; am I misinformed with my offset/tire specifications?

I am honestly pulling my hair out being that this is my daily driver and I have not had a car for just over a week now trying to get everything dialled in. This has been a total nightmare. I really do appreciate everyone's help, and look forward to resolving these issues. Thanks,

Jeffrey

I think your problem is the 35 height rear, those are too tall for your car.

Car looks sick! Can't you just pull the rear up a few threads? Seems like a good solution in your current situation.

Yeah if youre sitting on coils simple solution is to adjust them up enough so it no longer rubs. I'm in a similar predicament as you except I did not have coils and had to source a set of ride height adjusters for the rear.

That is something that I am really curious about. I just don't want to go order two tires without someone specifically saying that was their issue. It would be a costly test.

Thanks for the compliment! Raising the car is not going to resolve anything. When you lower the car natural camber increases. The range of motion will stay the same. Even with the car being higher, when I hit big bumps, the car will still rub. This is a clearance issue which i believe to be related to the tire choice as mentioned above, or the offsets.

I hope someone can chime in which has been in a similar situation.

Have you tried to look where it rubs? Any marks on tyre, fender or fender liner? I'm not sure but does E92 have same metal piece at the fender/ bumper bracket where the seam is. In this picture inside the fender behind the red arrows is small metal edge.https://i.imgur.com/ZSS1YOu.jpg

My setup only rubs there and it is 18x10.5 et15 with 255/35/18. I will be cutting piece out from there. My car is E90 so little bit more room, but i have lower offset and the tyre is correct aspect ratio for 18 inch. Your rear should be 255/30/19 as others have said, which probably solves rubbing issues. Or if you can get more camber with your stock adjusting that might help. I have -3 degrees and toe is close to zero.

One solution is to cut the inner fender out.

I remember when I ran 275/32/19 on stock sport suspension with a non aggressive offset and I would still rub. It does make sense bc your tires become taller thus you have extra height for it to rub inside your fender.

I'm also looking for the same specs as yours. Any rubbing issue on the front? any neg camber on the front?

It's honestly rubbing from front to back, the back bracket area being the worst. I partially grinded where the bracket is located, but it obviously wasn't enough. Im considering on cutting/re-sealing the rear quarters but I am afraid of corrosion being that this car will be driven through winter.

When I had the car aligned yesterday the max he could put the camber at without going out of spec on toe was -2.7 degrees.

I think I'm going to order the new tires and go from there. This is an expensive mistake. Obviously you can't always rely on vendors.

It does make sense. I should have gone with my gut.

The front is perfect with -3 degrees of camber. I have camber plates, and you will not be able to get the fitment perfect without them.

Ok. You might need to add some Fk bumpstops, but since it's rubbing constantly those probably wont help much yet. You should talk to Marcadelic. He has 19x10.5 et22 with 255/30/19. http://www.e90post.com/forums/showthread.php?t=864080

That's a lot of front camber i only have around -1 in my 18x9.5 et22 front with 225/40/18, but i guess your wider tyre requires it.

255/35 are over an entire inch taller than 255/30 which would be the correct size to use

You sir, are extremely helpful! I sent him a message, but I can already tell from his pictures that there is a night and day difference with the tire sizing. I know different tire brands stretch differently, but the V12's have pretty soft sidewalls, so I can see them being comparable to his tire choice. Thank you for pointing me in the right direction!

Here are some close of pictures of the clearance on both sides;

Thanks for looking! Any input is appreciated.

like i stated before I was on stock sport suspicion with 35 height tires and I would rub. You can tell it's way too tall and I can see how your car is barely dropped as is.

I don't even understand why vendor would sell you wrong aspect ratio tyres. They should know better and in my opinion they should compensate it some how to you. If we are really precise front should be 225/35/19, so it diameter difference is less and you could use less camber.

I fairly sure your rubbing issues are gone after new tyres and you might also need to cut part out from that inner wheel housing, which is some kinda felt material. I had to do that. You might already have burned through it tho. Just by looking the rubbing marks on the tyre.

By the way here is E92 with your current specs and same size 255/35/19 tyre. don't know if he had rubbing issues tho and it doesn't really matter anymore, since you are going to change it to what it suppose to be, so you can have less or no rubbing and you can go low again. http://www.e90post.com/forums/showpo...&postcount=558

But there are so many people who are running the same specs in this forum...how can they fit it? Also, do you think +22 too aggressive? Is it possible to run higher offset, e.g +25 or +28...for these offset ...enough space clear the strut or not?

As everyone says, it looks like a tire problem. It's hitting right at the top of the tire, so if you went to 30 series tires, that would buy you another .5" clearance right there which may be enough (1" overall height so .5" sidewall).

Are your fenders rolled? In some pics, it looks like no since there is a lot of metal there still. But in others, it looks like the fender has been rolled since the edge bulges out a bit. If not, that and properly sized tires would fix your problem. I don't think it's the offset.

I'm running a 295/25/20 V12 on a 10.5" wheel and it's not rubbing. Not sure of my offset since it's a custom wheel and they never told the previous owner and I never measured. I had to roll the fenders and pull them a tiny bit. I had to do the most work at the bumper/quarter junction. That area was rubbing the worst, it contacted more than the top of the wheel arch. Looking at your pics, I think if you flattened that out more, it would really help. I kept rolling there all the way to the junction.

My rim doesn't poke nearly as much as yours and I have strut clearance even with the big tire so if you decided to go less aggressive, there would be plenty of room. But I don't think you'd need to.

Go to willtheyfit.com and put your specs in with 30 vs 35. You'll be able to see the diff in height

No one runs a 35 height tire on 19 inch rims.

255/35/19 is too tall. You should try and go with a tire with a shorter sidewall.

Thank you kindly for all of your responses. You guys all gave me the confidence to go ahead and purchase the appropriate sized tires. The fenders are actually rolled quite aggressively, so I hope I will have no further issues. I should be receiving the tires this Monday, so I will get back to you all with the final results. Cheers,

Jeffrey
