how do you

measure the et on a wheel ?

The datum is the face that mates to the hub......

Ok, imagine you have a cross section of a wheel, draw a line thru the cross section that goes top to bottom, with the face that mates to the wheel hub as the datum. the distance the mating bit is off the center line of the rim, thats the ET. i think its - for towards outside the rim.

Thanks. what it is I have just gone to fit my mim 1900's and the fronts are hitting on the cailper I cant see where it tell you the et on them. I need to work out what spacers I am going to need.

chances are you'll need a spacer shim to clear the caliper about 3mm thick?
