Stock 18" Wheel Question

Does anybody know the offset of the stock 18" wheels, front and rear? I haven't taken mine off yet to see if it's mentioned on the back.

I ask because I want to buy a set of wheels/tires for the track and want to upsize (I'm thinking to 18x9F and 18x10R, 255/35F and 275/35R)

Sorry if this was posted elsewhere, I suck at searching forums.

The info is in a sticky post at the top of the wheels section:

You can easly go up to 9.5 F and 10.5 R without running into any issues.

Thank you very much. So if I go w/ 18x9s for the front, look like I'll something like a 25mm offset and then 20mm for the rear 18x10's.

That should work. See my track setup here for some more ideas:
