Just as the title states, I only have a one wheel wonder and the passenger side is the only on that spins and it is killing my times at the autocross track. I was told I need clutch packs to get them both spinning. I was looking at other alternatives. Like the Auburn or Eaton or Torsion diffs. I want something that is not going to let my tires go up in smoke when I am taking a corner at 40 mph. I don't drag race, I just want traction. Should I just get the Ford clutch packs or upgrade to something better?
