In the not too distant future I'm going to be installing a set of FRPP 3.73s in my 02 GT. It's got perhaps 25,000 miles on it, give or take, and I was thinking about freshening the Traction Lok while it's out with new steels & frictions. I can get a rebuild kit for about $50 which seems pretty reasonable.
Talk to me about the pre-load spring and the benefits and drawbacks of going to an F-150 S-spring (F3TZ-4214-A) versus the original Mustang unit (E0AZ-4214-A). Obviously, the torque bias will be increased quite a bit with the heavier F-150 spring but how will this be manifested as a drawback or benefit on the street? The car seems able to easily one-wheel peel around some corners now but in a straight line will lay a couple of fat, even burnout tracks. I don't want a real squirrely rain car either so the diff still has to slip a bit around corners...
What is the factory bias and what would it be with the F-150 spring?
Or should I just replace the clutch packs, leave the factory S-spring there and be done with it?
