Outer Limits 4x4 Board

i want 31's on my coily i have 30mm king springs and a 30mm bumpstop extension in the front and i am doing a virtual lift. will they hit the firewall. i would rather not cut the firewall if i dont need to.
also how much offset sould i get on the 15x8 rims . i want as wide as possible . iknow this will bring the edge closer to the firewall at full lock


thanks in advance luke

the fronts will hit on the firewall, think mine hit on the fuel house cover in back, not sure about offset tho...
