4.30's all the way on that S-197, it's a V-6 right, 4.30 don't fear the gears, there your friend

I think I have a used LSD for that car. Its a Ford unit but its out of an 8.8 with 28 splines. I dont know what size carrier the sixes use. And I agree, DON'T FEAR THE GEAR

 

[NYstang]

he has a 7.5


You would have to swap in an 8.8 to get a 3.90, but I would do 4.10's. that and a tru-trak LSD will have you pretty happy!

how much

Theres no definite answer to this without knowing what your goals are, what tire you will use, what RPM you'll rev to and how fast you want to go. Guessing what gear you want will only secure multiple future gear changes till you get it right.

your gonna need a tuner to fix the odometer as well. or next thing you know you will have 20,000 miles when it should only be 12

Ghostly Echo,I went with a 8.8" Rear Axle Assembly 3.73:1Ratio w/ABS w/Trac-Loc Pinion Flange For Mustang V6 rear from New Take Off. Brenspeed for a SCT X3 tuner. 07 Ferrario/Roush (Dealer installed stage 1 package, with a few mods of my own) AKA Mr. Ed.

Your stock gears are what? 3.31? If this is the case I would say at LEAST 4.10, probably 4.30. 3.73 would be a nice jump but I would almost guarantee you would wish you went steeper.
