Check my Offset Math

Ok, so I have 30mm spacers behind 16x7 +33et Boost alloys. I also have a set of P38 Mondials that are 18x8 +56et. In order to run the monorails they would require a very beefy 65mm spacer.

So:

Boost wheels are just about flush with the outer edge of my flares.

+33 et and a 30mm spacer makes the Boosts essentially a +3 et offset wheel.
+56 et and a 65mm spacer makes the Mondials essentially a -9 et offset wheel.

so this means that the Mondials will stick out an additional 25mm past my current wheels?

That is sweet app Don! What is it?

Dale, I have the spacer adapter here. I'm not crazy about the design. It's at least a half inch thicker than needed to clear the flange bolts. I thought about making my own but my confidence in making a wheel adapter is low.

That's not really the issue. I'll snap some pics tomorrow. They just need a redesign. There is too much material to bridge the flange and provide a hubcentric centerpiece by ring.
