I just put a big brake kit on my '12 G37x sedan. I currently have OEM 18" Sport wheels that are 18x7.5 ET45 and am using 15mm H&R spacers. Brake clearance is (barely) fine.

Current wheel style is this (not my picture, only decent pic I could find with the wheels):



So, I currently have my winter tires on these wheels and plan to leave them on.

I'd like to get another set of wheels for my summer tires but I want to ditch the spacers when I use this set of wheels. I'm going to use the stock tire size (225/50-18) since I have new Pilots.

So, is my math correct that I need to look for ET30 wheels?

Does anyone know of OEM 18" wheels that are around 7.5" - 8" wide with an ET30 offset?

I know that the spoke design is most critical when it comes to clearing the big brakes but I figured I'd narrow the search first by looking for the correct offset.

Thanks.

 

Why not get the sport 19" wheels? Looks great on the sedan.

 

18" Z wheels will clear your BBK

I think the 18" OEM Infiniti base coupe wheels also clear the BBK but not 100% sure.
