Volk Rays 18x7.5 (F) and 18x8.5 (R).

Offset is +45.

Will these clear the brakes on a '12 G37S Sedan?

In order to use the calculator on this site - I need to know the offsets of the stock wheel?

Any info is much appreciated.

Thanks

 

Not sure about the Volks but here's all the OEM wheel specs, your 12s are the same as the 2nd Gen Sport Sedan listing at the bottom of the page
