15 mm spacers rear

The 167 M's are ET 17 (perfect) and the 166 M's ET 28 so they will need a 10 mm spacer.

I suppose those are the best choice for a E60 as well.

Interested to hear what happened!

 

M166 ET28 do NOT NEED SPACERS. I am driving them and don,t have any problems.

Something must be wrong withxBMWx test..

 

I am currently NOT having the M166 ET28 rims fitted, but having the type 128 ET32 fitted. To state the obvious, ET32 means the inside of the rim is closer to the inner arch than an ET28 rim... which is why you are ok with your M166 ET28 and I need spacers for the 128 ET32.

What you also have to remember, is that I am having to get this formally tested and approved by the German authorities (T?V) for insurance purposes. T?V may want to see more space between the rim and the arch than you and I would feel is necessary, i.e. they want to be "extra safe" before they put their approval to it for road safety etc.

To be honest I really don't care what size spacer they use, as long as its safe to drive with -- which is what the T?V testing and approval is all about.

Thanks for the feedback guys, it will be useful next summer when I go through the same process with my M166 ET28 summer set-up... something to look forward to

 

15mm spacers is the worst thing you can do becuase when oyu mount your sumemr wheels in summer, your wheels will stick out too far and T?V wont approve your 166s with 15mm spacers. and changing spacers every 6 months is one terrible thing. look at the pic of spacers i "bullied" off my car

 

well I'll just have to deal with that problem next summer... either I get my M166s to fit (by rolling the outer-arches) or otherwise sell the M166s and buy a set of M172s or another set of 128s with ET32. I just want to fit my 19" 128 winter rims... now!!

thanks for the advice mate, and yes, I am expecting to hear an " I told you so" from you some time next summer...

 

me???? i would never do that

how about 13mm as a compromise solution?

and remember - tell whoever is mounting the spacers to use lots and lots of grease - he might as well use all the vaselin he can find

 

If this was a Mini or something I could understand all of this, because there is less space under the arches. But using 2mm smaller spacers on a 5er to make it fit ?!?! I simply don't get it -- its all too much for my small brain to understand

Thanks for the advice on the grease, I will call them now! I'll also ask them to take off the existing rust from the hub and rim, i.e. get it all as clean as possible to reduce the bonding.

 

ok - let us go through this step by step:

10mm were too little becuase it rubbed on the inside part of the wheel. Which means that an et of -22 (-32 + 10) is not enough to avoid rubbing of a 9,5" wheel with 275s. So T?V recommended taking 15 mm. This means - the 128s now fit perfectly in your touring with overall ET of 17 (-32 + 15 = -17). If you now kept these spacers, and mounted your 166s in summer, then your ET changes, because the 166s have et 28, so your overall ET is 13 (-28 + 15). With ET 13 on 9,5" with 275 wheels, i can tell you now arealdy, that it will stick out too much (probs with the outside part of the wheel rather than the inside you had with 10mm in combination with your 128s).

So my recommendation is spacers with 13mm. This gives you for your winter setup an overall ET of 19 which works because my colleague wiht his touring had it approved by austrian t?v (if you think your t?v is tough, you dont wanna meet ours - they put 300kg of sand at the back of your car when testing the car), and the same spacers will work for your summer set, giving you an overall et of 15 (which i in turn had ok'd on my car without playing aorund extending the body parts)...

and yes, the 2mm makes a big difference, like with any man's body part

 

10mm should work

 

The 10mm failed the T?V approval testing -- they said it was too close to the inner arch. (I think 10mm may have been ok, but T?V probably wants to see more space to be on the safe side??) So the garage ended up fitting the 15mm spacers. As Rsyed pointed out about, this will probably give me problems with my M5 rims in summer, but I might just sell / swap these for M172 rims, which have the same ET32 value as the 128s I just had fitted with the 15mm spacers.
