Hi, Nick.
[quote=" 90Q45blue Z, Where did you get those wheels? [/quote] An eBay auction. The guy had both types of G35 wheels (45mm and a 30/33mm combo) up for sale. The 45mm ones came off a 2002 G35 sedan.
They are 17x7 and I am wondering if Infiniti has decided to change the offset for the 2003 to only the 30/33mm, since I am seeing 17x7.5 with the same 30/33mm offsets for 2003 wheels on eBay.Quote »Compared to the other prices I'm seeing 660 is a good deal.[/quote]Yeah!

That is why I went for them, although I actually thought it was a bit high, since they had more than the usual tiny miles on them.Quote »Also, I'm having trouble finding the 45mm offsets.[/quote]I suspect that this is because the the 45mm offset wheels were only used for the sedan and not the coupe. The coupe purchasers are probably far more interested in changing the wheels (to 18" or 19") so they put their OEM 17" rims on the market more often. The sedan guys don't care as much probably. This is, of course, a complete WAG!
You may want to ask the eBay or other sellers, if they have not specifically listed the offset, to look inside the rim for you - the offset is clearly labelled (embossed) in the metal.
Joe Tsensky at Scottsdale Infiniti has occasionally listed new G35 take-offs in the past for not too much money. You might want to drop him a line and see if he has anything available in the right size ...
