My fronts are 17x8, 25mm offset. The arms are 10mm longer, They didn't make the wheels in the offset I wanted so I had to add it at the arms. With 10mm less wheel offset my track would have been the same though.
Justin, I can get the tire to frame rail to tire measurement next weekend If there is another measurement you want off it I can get that too. I think the wheels on that SC are 7's.
