These are specialized products that require specialized skills to setup.
I wouldn't expect much documentation for it, you need a diff builder to set it up as you aren't getting much help from the manufacture.
Just installed mine for a Spec E9X build
dmytro98 any updates on your experience?
I went with a "less aggressive" setup iirc it is: 1.5way, 60% lockup, 60ft-lbs of preload.
I was also warned of all the noises, "it will sound broken" as you break it in. It's a metal plate diff, it will always be noisey.
Anyways I just backed it out of the garage after installing it last night. I plan to break it in this weekend doing the figure 8s. Then I will change the 10w30 conventional oil I was told to use during break in.
I already heard a bunch of funny noises driving it down the street and turning around.
Will update in a few months after I break it in and get it out on the track.
