My car will be 5-lug. The car is completly apart becuase I have to weld in a new torque box, 1/4 panels, floor boards(patches), some front sub frame, and a roll cage. So at that point it would be very easy to also do a mini tub. With a good set of Rear uppers and lowers I dont need quad shocks anyways, so I should be able to get a 315 on it fine.
