I'm seriously considering putting on the OEM 18's onto my Coupe and was just wonderin' if it would affect the handling or suspension in any NEGATIVE way? Thanks

 

I am looking to go to 17's for the winter and was told by Infiniti there would be no problem.

 

If you replace the OEM 17's with OEM 18's your handling will improve a bit, but with a slighty stiffer ride.

I personally chose the 18" rims cuz they look alot better than the standard rims, IMO.

Also you'll have to replace 18" tires sooner then you would with 17's, plus 18" tires are more expensive too.
