Our FD race car now has a Dana 44 rear diff but it's only about 55%. As w e see a lot of short circuit and short corner tracks we need a diff with a higher slip percentage.

Currently we have the Dana 44 which came with the car but this seems to be an old item and we can't get anything for it that we need.

Can anyone point a diff alternative with about 75% slip that will fit the FD, even one that goes with the Dana44 housing without to much modification?

Diff should hold up to about 500-600HP and has to be race proven (cooling etc)

Thanks

Can you post a picture of that Dana44 setup in the FD?

Did you use a C4 Corvette or Viper Dana 44 rear end? Something else?

Are you running stock FD style suspension with custom halfshafts to mate up to the FD rear hubs?
