GRMN LSD is declared to be a little more "open" on the first phase, to help entering the curve. So I think it has different gears on Torsen leverage, basically related to wider rear wheels of the GRMN.

It looks that you don't understand the details of how a Torsen differential work. Torsen has a torque bias ratio (TBR) and in the normal case it is a 4:1 rate. This is also called its lock rate, but the better terminology is TBR. So, the diff in the GRMN 86 has a higher TBR. It is close to a 6:1 rate.

I am not trying to build a GRMN 86 replica. I wanted to solve a specific problem I had, caused by bad road pavement conditions. I found that the best option would be to use the specific diff and it works perfectly. Someone might say that an OS Giken diff or other clutch plate would be better, but everyone can have its opinion here. What I can say for sure is that GRMN spent a lot of R&D to build the specific diff and yes it makes a difference. Another thing to know is that Torsen (JTEKT Corporation) is actually owned by Toyota, so they know what they are doing.
