Hey Bill,
Who's cars are those? Do you know the specs on the wheels (Size and BS)? I would also be interested in knowing what suspension setup they used to achieve that stance... I really like how those cars look and sit. I think those HREs with black centers would look SICK on a GNX clone.
Sledgehammer (the car with the Simmons wheels) is owned by RobsIron on here.
Wheel specs as far as I know are: 18x10.5s and 18x9.5s. The rear frame was notched 1" No idea on the backspacing
The car with the HREs was just for sale on Ebay a while back and I think some dude here bought that. Not sure who though
