Just had Forgestar F14's in gunmetal mounted on my 2001 base. Was running stock 17's before, went with 18's on the Forgestars.

The Forgestars are light...even with much bigger rims and heavier tires, I'm only up 2lbs per in the front and less than that in the rear. Appologies for the grainy cell phone pic...
