I had 4.10 gears in the Barracuda for about a month, pulled them and traded them off. I could not get traction at all, I don't know how you guys with big motors keep traction on the street with a car made to take corners.
Once you go over 500ft lbs on a street car, if you aren’t breaking traction you are probably breaking something else. Better to fry the tires than the clutch/u joints IMO.
