Lude Generation

Hi everybody!

Actually i have two ITR torsen and a M2K4 gearbox (4th lude gen H23 ).
I was wondering what is the difference between ATR and ITR torsen.
I know that i can mount them without any problem into the M2K4 gearbox but i don't know if the torsen gears are different or not.

Thanks for your help!

Ok, so it seems that nobody here have the answer to my question

So, when i'll open my U2Q7, i'll open up the torsen and i'll compare it to compare it with my other spare ITR torsen
