Let us know if you find a space saver spare that works. There's no longer a place to mount a spare in the trunk so it will just be loose.

I have attached a picture of the spare tire that I had bought from eBay about a month ago.

I have also attached a picture of the potential spare tires that should fit our cars and clear the brakes (145/70R18 spare tire for G37 or 370Z or Q50) by doing a search for:
Q50 Spare Tire
on Ebay.

And yes, i test fitted the spare tire that I received on both the front and rear of my car, and it cleared the brakes. So, I am pretty sure those spare tires from eBay should work on a Q60 RS RWD (but unsure about fitment/placement in the trunk of the Q60).
So if you had to use the 18 inch spare on the rear, wouldn't it be an issue having a 18 inch tire on one side and a 19 inch on the other?

Took the plunge and bought the 145/80R17 wheel off ebay. It fits great on the 3.0T Premium with the 12.6'' front brakes. I couldnt add pics below but there is clearance for the brake caliper, also because of those welded blocks, having the spare and jack in the trunk doesnt leave much room left over for anything else.
There's still a cutout for a Nissan scissor jack and tools.

Just got a Q60 with the 255/40/19 RFs. I stopped by our local discount tire direct branch and they compared our OEM tire to the Spare 145/70/18 size listed and gave me the following differences:
Spare OEM
26" Dia. 27" Dia.
81.6 Circ. 84.9" Circ.
776 RP/Mile 746 RP/Mile

he said I should check this is okay before he orders me anything. Anyone want to chime in with thoughts?
Since I have a RWD I'm only going to use the spare on the front. So, If i get a flat on the rear that I can't repair, I'll just move a front wheel to the rear and the spare on the front.
