I can tell you first hand as I did the install myself last weekend that it is a drop in fit. Everything was in spec and utilizing the included instructions and FSM I had no issues at all.

As for drivability I can only say that with figure 8's done and 100 miles or so of highway driving it is very quite. I have it set at 80% and with VDC on turning slow tight corners activates it a little.

I will be tracking it this Sat and Sunday on new BFG R1 285/18 square which should be a good set up.

I can give some further feedback on this LSD after this weekend if you want to hear more.

Wanted to follow up with my observations after tracking with the LSD this past weekend.

1st: Having a proper LSD is a night and day difference putting power to the ground on corner exit. Much more precise feeling like you are connected to the car and instantly know what your throttle input is doing to the car dynamics.

2nd: High speed breaking, I have the 1.5 way set at 80% and didn't have any negative feeling the car wanted to lock up on down shifts or hard breaking zones...very stable.

3rd: My cooler works great

nothing over 230 deg during 8 20 min sessions.

I mentioned that I went with this due to price. I bought mine through buyee.jp for $900 us + $75 admin fee + 250 Shipping = $1225 I may have had another small fee but, the total was not over $1300.

This is sold as a kit with new seals, bearings, ring gear bolts, and stub axles. You also get 2 qts of Nismo gear oil. You pay the extra cost of all these items with the other LSD's.

The big negative is the wait. I waited almost 2 months before I got it. Once they received and shipped, it was at my door in 4 days.

Install was pretty easy, just follow the included directions. I measured backlash and side bearing clearance on the stock one before I dis-assembled. side clearance was in spec backlash was .007 which is .001 over spec. With the new LSD installed I came out at .006 backlash and had a picture perfect pinion gear to ring gear mesh pattern. Fit was spot on

Anyway there you are hope that helps
