I have a seller selling a set of Vossen CV3 19x8.5 in front and 19x10 in the rear from a Scion FR-S and was wondering if this set would be able to fit into the G37S.
It is a great offer i found and if all it would take to fit these on my car was a bolt adapter, then i am considering pulling the trigger on this.

 

Do you know the offset? The spacer to change bolt pattern would add perhaps another 10mm.

 

Bolt pattern is a 5x100 and would have to verify offsets. If you have enough positive offset to run the spacer/adapter it could be done.

 

he says it's +42

 

nevermind +45 in front +50 for rears

 

If you can find a 15mm adapter thats listed as 5x114.3 to 5x100 that would work~
This would net a 8.5+30 front and 10"+35 rear, those offset would work as long as the wheels clear the big brakes (they should be should contact vendor/seller to verify, these templates are handy to send them if needed

One of your posts you said a 8.5 & 9.5, the other you said a 10" rear.
If you have the 8.5/10 combo I'd run 245/40/19 front 265/35/19 rear, those tires would also work fine if you have the 9.5" rear.
Even better if you could find a 10mm thick adapter, not sure about that

 

it's a 8.5/10...i wrote the thread title incorrectly and couldn't edit it.
so i see that on the website you provided, there are 15mm and 11mm..if the 10mm thick adapter would be better than the 15mm, then would the 11mm be better than the 15mm as well?

 

With your listed offsets, you might want to run thicker adaptor like 25mm front and 20mm rear to bring your wheels semi flush.
