To tell you the truth I'm not exactly sure the offset as I let Forgestar pick them for me. I know the offset is more aggressive than the stock wheels by approximately 15mm but given that the wheel is wider I don't know what that translates to as an exact offset but you should be able to calculate it.

Hey there! I was wondering what wheel setup you use for the track. I think in one of the threads you mentioned running 10" fronts and 11" rears with 275/315. I don't think I'll have a problem with fitment in the rear, but what offsets are you running in the front? Thanks for your help!
