Hey guys im planning on gettin new rims and tires in a few days and i dont know what offset/backspacing to get to match as closely to what i have already.. I have 20x9s on a6 in procomp stage1.. Im wanting 17" rockstars

 

Want them like stock or sticking out?

 

I would like them it sit just like the ones i have now do but i dont know the backspacing and offset

 

Go measure them and see what they are, or check and see if it's stamped on the inside of the wheel. Or post what wheel it is and we can try to narrow it down from there.

 

Email me a pic of the wheels and I'll post it. If they're Motometal 951's, they're almost always a -12 offset with our bolt pattern IIRC

 

Se i dont know if i did it right but i came up with like a 16 offset but i dont know what im doin

 

I'm stuck at a classical music concert right now . . . but I'll post that pic up when I can get on my laptop. I can't ever seen to accurately measure offset and back spacing when I've tried with a ruler, etc either

 

just look on the inside of the wheel. dont bother measuring

 

Ill go do that but since im going with a 9 in rim from a 10 where do i compensate for that because id like so keep the same stance or even a hair wilde

 

Lower offset or backspace to compensate for that loss of an inch. But go to low and your wheel bearings will hate you.

Are the wheels you have now 20x10 or 20x9 though? Because your first post says 20x9, but you just said they're 10"..

 

They're like 962s with grooved spokes, not sure what they are

 

Moto Metal 954's, discontinued.
20x10
-18 offset
4.79" backspacing

I wouldn't recommend a wheel with less than 4.5" of backspacing due to bearing stress, so your gonna lose some of your width going to a 9" wheel.

 

Ope, found em. They're discontinued 954s. Looks like they were available in only 20x10 with a -18 offset for our bolt patter.
