Hi,

I am looking to buy some wheels off ebay. My car is a 04 545i.

I have the following choice combo

19X8.5 +12mm and 19X9.5 +28mm (72mm hub)

or

19X8.5 +15mm and 19x9.5 +20mm (74mm hub but will probide ring)

What do you think is the best and would not rub (with 275 in the back) if I decide to lower the car with eibach springs later on.

Thanks

 

hi,

you have to give us the spec of the wheel, ie. the offset of the wheel. if you are for example looking into the 167 m6 alloys with offset 17 in the rear, then 20 mm is far too much, whereas if you get a set of 172 with offset 32 then, 20 mm might just be ok. again, really depends on the offset of the wheel..

Well, I think he has given the offset of the wheels.

9.5x19 ET20 with 275/30 are not the slightest problem on the rear.

I had 10x20 ET20 on mine last weekend and even those fit perfectly fine. (i also have the Eibach on)

 

oops, you are right. i was thinking that those were the spacers he wanted to have put on them... sorry

 

HI Many thanks for the help. However, at ET20 in the back, will I need spacer to make it look right ? What about Et28 in the back, does it show a lot of difference from a viewing stance ?

Thanks

 

am a bit confused - with et20, you are less likely to need spacers than if you have et28 provided we are talking about the same wheels but just with different offsets. but fyi, with e20, spacers of 20 mm is way too much. check out http://www.syed.at/e60/images/IMG_0717.JPG -> that is with et 28 and 13 mm spacers..

cheers rumman

 

To my Understanding,

When the Offset if positive, the higher the number is, the further the bolting points are from the center of the wheel, wich mean once the wheel mounted on the hub, the portion of the wheel that stick out is less compared with a lower Offset wheel. When you have offset ET20 and put spacers of 10mm, that will make your wheel sitck out further toward the fenders, wich mean that the bolting point is now closer to the center of the wheel. Adding +10mm spacer to a positive offset wheel will reduce the offset by 10mm. IE, if a wheel is ET20, adding spacers of 10mm will mean that the wheel is equivalent to ET10.

This said, if a wheel has the same width, and if the offset is ET20 Vs ET28, the Et20 will stick out 8mm more toward the outside of the vehicule(fender) that the Et28 wheel.

Hope my understanding is correct...

 

You've got it. That's exactly what it is.

20mm spacers on an ET20 wheel would transform it into a ET0.

 

i totally agree with you, i was just confused from the first quote where i thought you were writing about spacers for et 20 but no spacers for et 28.

 

So now... Maybe someone can answer wich wheel setup is the best choice for me
