Does anyone know if there were any wheel / tire combinations that were available as a factory option for the 2007 G35x other than the 17 x 7.5" Double 5-Spokes with 225/55/17's tires? I want to go back to the "stock" category for Autocross next season but 7.5" wheels really suck for tire choices, but I have to run wheels that were available from the manufacturer as either standard or optional for my trim... I'm pretty much stuck running 235/45/17's which are 5% too fast on the speedo which I don't think is a good idea running daily on the streets. Thoughts?

 

Get any setup that is square..
