I’ve got a 2019 GT PP1 with the Torsen diff. Temps keep getting high on the track (275F-300F) the diff cooler isn’t helping. Sent the fluid off to Blackstone for analysis after a weekend event at Sebring. Results after 500 miles on-track showed significant viscosity breakdown and high levels of iron. So, to cover my bases, I’ve got all new parts ordered from Ford Performance. New Ring and Pinion, new Torsen, rebuild kit will all the bearings and seals, also going to upgrade the half shafts while we are at it. Unfortunately, it appears that a new loaded diff case with all this installed is not available from anyone. I can buy a loaded unit with the traction-lock and the 3.55 gears, but not one with the Torsen and 3.73 gears. Since this is a fairly intricate job and some experience is needed setting back-lash, pre-load, and pinion depth, I’m trying to find a shop that has some experience rebuilding differentials on performance cars. I’m in Athens, GA. Closer is better but willing to go anywhere in Georgia, South Carolina, Tennessee, etc.
Any suggestions?
