I am one of the many that have pre-ordered this setup. Well, not the exact one you are asking about but the complete track attack kit, front and rear.
These were all components I needed to upgrade and I attempted to piece together the old Z Car Depot setup but there was way too many parts needed. After I bought the Z Car Depot I setup I ran into issues with the brackets not being correctly fitted. They had since fixed the issue and I had since sold that kit. That is where I learned Ohm was looking to do the 8.8 setup (which he already had a prototype in his personal car dating back a couple of years). I was fixated on the 8.8 for diff availability, gearing, price, and aftermarket support.
I should have it in my possession within a month's time and plan to do a pretty decent write up. Ohm and Apex has had my attention on this for a little over a year and it marks a lot of the checkboxes that I was looking for.
I am not a drag racer, I plan to actually track my car. I wanted an upgraded diff that could hold power (Ford 8.8 from the explorer has seen over 700 wheel hp), available gearing, pricing. The bottleneck is usually the factory limited slip but at 700hp, not many are actually going to hit that mark. I needed coilovers and this setup includes them and on paper seems to outshine. Of course no one has really ran this setup yet, but everyone has to start somewhere. I am okay being that person.With the coilovers being moved to the trunk area I will have access to wider wheels without needing to flare. He has said that a 315 could fit behind the factory fenders. I am sure your mileage can vary depending on wheel height etc.
Through my numerous communications with him, he is addressing the axles as well. You shouldn't need to take any axles apart. The beauty of getting everything from Apex, the measuring is already done. Something I know I would mess up when having to send them out to respline. He has an option to use DSS axles. I will be running that at least.
I recently sold my Hoke Performance mount kit as well (there was nothing wrong with hokes kit, in fact it was beyond amazing. Hoke made the first true bolt in LS kit for the datsuns imo) and opted to go all Apex. Was just a preference thing to go wtih all the same brand. I'm weird like that I guess.
I am not sponsored or affiliated with Apex in any way. I know saying this might create skeptics but you were probably skeptical before that. I am in CA, he is in WI.
