The dust cap has to come off in order for a 10mm or 12mm spacers to fi ton the rear. Even the 15mm squeezes the dust cap, at least it did with the Ubercentric ones, H&R may have a different fit.

I don't mind removing the dust caps, really don't see the point of them honestly. I'm sure others will chime in and say if BMW engineers say they are needed, then they are needed and BMW wouldn't waste money on useless parts and maybe it's true...I just don't see why BMW's need it when no other car does.

Got mine on... 12mm all around...

[pikcachu]

had to put the dust cups on the spacers with some silicon glue

[HX_Guy]

Nice, you did it! How are you liking the 12/12 setup?

BTW I tried that silicon stuff though, though mine was epoxy. The first time I went to mess with the spacers, the caps fell off..guess the epoxy didn't quite resist with the heat that those things probably heat up to.

I really like it.... not too aggressive...not too tame...

The for wheels are still on

I decided against the 15mm front and 12mm rear...will do 12mm front and 10mm rear, but I am thinking maybe 13mm front would be a good compromise. Definitely 10mm rear though.

BTW the car looks terrible now without any spacers...just looks so weak, I don't know, looks so off. Spacers are definitely a must, or aftermarket wheels that are either wider and/or better offset than stock.

What was improper about the fit? Thickness, dust caps, if you can explain. Also what exactly can a spacer do to contribute to road vibration if it was not already there? Thickness variations causing small wheel run out frequency?

Just curious

[pikcachu]

if the spacer is not balanced you will get wheel vibration....as well if you don't clean the hubs and the spacer doesn't sit flush against the hub

On the 5mm spacers, the stud holes were not precise and one of the lug nuts would bind up when tightening it.

On the 12mm spacers, there would be vibration in the steering wheel between 40-50 MPH only and on the 15mm spacers, there would be vibration at 80 MPH only. Could be they weren't exactly in thickness or in balance, who knows.

Cool...let us know how the next ones work out...I didn't see any of the spacer manufacturers claim they balanced their spacers. Also I think the closer to the spindle center an item is (small diameter) the less effect rotating weight has on balance. But not sure about run out

[pikcachu]

well i mean the probably build them to be balanced... else it will create vibration when it spins
And some might be better balanced than others

Pikcachu - what size lug nuts did you use?

[pikcachu]

didn't check they came with the spacers... http://www.burgertuning.com/BMW_wheel_spacers.html

but there seem to be about 20-15 mm longer

[Roshi]

HX_Guy - did you ever get new spacers? Or just looking to get new wheels first?

[HX_Guy]

Looking at wheels now to where I wouldn't need spacers.

[horsepower_and_hounds]

What is being done with the spacers? I am still thinking of doing 12f 15r or close to that

[HX_Guy]

I returned them back to Amazon.

How about 15/15 - is that a no-go?

It's just a matter of taste... those will stick out a little bit more...

pikcachu looking at your pics it looks like the car can easily handle 15/15... just wondering if it will cause clearance issues..?

dont think it will cause any issues

First, thanks for all of the testing that has been done with the various sizes of wheel spacers.

Does anyone know how far can you space on the front and the rear before the tire would be at risk of coming up and impacting the fender/quarter panel?

I love the look, but the roads around me sometimes aren't the greatest, so I'm curious how far I can space out without causing problems going over larger bumps/potholes.

If someone interesting, there are new spacers from H&R from end of 2014 where you don't need to take off dust cups.

I have another question. I put 10 mm spacers on standard 461 wheels and got the feeling that handling became very sensitive for trace changing, like car goes to side where the trace not that flat. Is it a normal thing by using spacers and will it be gone without spacers, considering the fact that I rode 205/50 in winter and in summer now is 225/40 on the front and 245/35 on the rear witch is already much wider without spacers?
