What's the widest wheels you can run on a stock FC and also the offset so they don't stick out too much. Thx

 

Anything?

 

Dude, there is an entire wheel fitment thread just for FC. For most people, a 9 +20 through +25 is about as big wide as they will go up front. If the wheels are any wider, non street friendly amounts of negative camber will be needed to fit them.

Reted's site has good information on wheel fitment: http://fc3spro.com/TECH/MODS/RT/rims.htm.
