    I own a 97 mustang GT with a 02 engine ready for racing supercharger making 510hp.
    and the only thing is missing is a good limited slip posi traction differential. and of course i need to upgrade to 31 spline
    Dayli drive Mustang and weekend at the track
    i have 373 gear

    My question is which is the best limited slip posi traction differential i can get to put all the power to the pavement?

    The Ford Racing Traction LOK LSD is a pretty stout piece. Eaton is a great company too they've been doin rear ends since the beginning if money is no object, Eaton, if it is. Ford Racing.

    OP: FYI, "Posi" is the name GM gives to their version of a limited slip differential. Ford's is called "Traction Lok".

    I'd think a Traction Lok would be fine but you'd want the carbon fibre discs and, if you're already planning to go to 31 spline axles anyway, consider the FRPP M-4204-F318C differential.
