Spacers vs Wheel offsets

well this ones got my head spinning.. maybe you guys can help me out..


Suppose i had a wheel 17x8.5 with a -6 offset and i added a 1.25” spacer to it for poke or stance.

Now let’s take a wheel 17x9 (with the same size tire) that had a -38 offset. Wouldn’t the poke or stance be very similar?

My math says yes: -38mm=1.49” plus the 1/2 inch in wheel width..

Help me out here.. i know someone has the formula or can steer me in the right direction

Thanks

 

Thanks been using that site for some time now.. but dint know the had an offset calculator too

 

They will sit pretty close.

1.25-inch wheel spacer is 32mm effectively, so a 17x8.5 ET-6 with 1.25" spacers effectively becomes 17x8.5 ET-38. If you account for the wheel width increase of a 17x9, the 17x9 ET-38 will sit 1/4" further out when compared to the 17x8 ET-38

 

Thought so.. I’m glad i stayed in school lol

So to answer your question, if it already hasn’t been or your still looking, I have 1.25” spacers on the stock rims and it’s not super aggressive but it is about an inch. I do plan to do more tho eventually. Also have a pic to give you some idea of what it looks like.
