18" BBS wheels offset question?

[lamb chops]

I have a set of BBS 18" split rims, I am tring to find out the offset but they dont have an ET number on them.. Anyone have any ideas?

OK, these pix were supposed to be on the other post !

.. you can see from these that if you measure the rim, then its easy to calculate ET

BBS wheel with no ET stamp on it? You are kidding... they always have it stamped on the inside of the wheel...

Thanks for the reply guys, wheel are BBS as it has BBS stamped on to them under the centre cap. I removed a wheel last night to look at the back but there was no ET number.. Under the centre cap is says 18x18 9j is22 I thought perhaps the Germans used IS instead of ET..

Thanks

ET and IS are equivalent.

You have 18" diameter by 9" wide rims with a 22mm positive offset.

Enjoy!

ET is an acronym for "Einpress Tieffe", which is German for 'push-in depth'
