Did you get the high performance unit or the OEM? Are you satisfied with the performance? If you got the OEM do you wish you had gotten the high performance one? Any help would be appreciated thanks, Tony

 

I have the HD Torsen differential and am very happy with it. It works great in the corners and I've pulled 1.96-second 60-foot times out of my small-cam 305.

I've got the HD Torsen in my 92Z, and the take-off for my wife's 96 T/A w/RamAir.

I like the HD unit, have about 35-40k on it,and it has withstood both the pounding I gave it with the L98, and the pounding with the 383. It is smooth on the street for engaging & disengaging around turns. No surprises as I've had with other units.

I've put down 1.914-1.934's repeatedly with my SZ50's with no problems. I like it.
