I saw the clearance issue, just wondering what is different w/ those 18s compared to the 18s on the RWD S models that are made to clear the calipers.
Do the X models have different offsets, it would seem so.

 

I am not sure if I measured or reading it correctly but with the 15mm spacer, the front has 21mm of clearance and the rear has 55mm. Please correct me.

Here are some fresh pics. You need to zoom in for the front wheel to see the measurement.

Just notice from the pic they ding my caliper

Any of you guys able to tell if these are authentic stoptech rotors? They dont look anything like the pics I see on various vendor website.

 

Just realize I am not respecting OP thread and trashed it. My apology OP, was not my intention. Let me open another thread.

I have 18" x 8 from a 2012 coupe on a 2008 G35x. They fit without spacers and very clean.
