I just got lucky and it happened to come with the car. The oem nav isn’t that great and I most likely would not have opted for it if I was given a choice, though the nav system between the ‘09 and ‘13 are quite different.

VLSD transfers some power from the inside wheel to the outside wheel in a turn. This effectively allows the wheels to rotate at different speeds to maximize traction and prevent slipping during a turn. Of course the VLSD isn't a proper track solution - the fluid overheats way too easily and it just turns into an open diff until it cools down.

A 1.5 or 2 way diff allows a lot more power transfer and is ideal for track driving.
Um, that's not how they work at all.

An open diff puts all power to the wheel with the least amount of traction if traction breaks loose. If one wheel breaks traction, no power goes to the other wheel.

An LSD enables some of the power to be split in that same situation, provided the needed breakaway torque to get power to the other wheel doesn't exceed the breakaway torque in the LSD. Clutch discs are used in the diff to provide that additional friction. Those clutch discs wear out over time and an LSD becomes more and more like an open diff. Nissan has always used minimal breakaway torque in their LSD units, greatly limiting their effectiveness. Same holds true for the old LSDs they used in D21 and D22 trucks. With those you could slide in 1-2 additional discs to "tighten up" the LSD, and with enough additions, you can basically turn an LSD into a spool where both wheels always get the same power. That's not desirable either because in a turn, that means the inside tire HAS to break traction to prevent binding.

Still wrong. Open diff sends power to the wheel with the least traction. It will send 100% of the power to the lighter wheel in a corner.

Not necessarily. I have a base with open dif, and have no troubles at all laying down perfect "elevens" in 1st and 2nd gear in a straight line.

In my experience. Sometimes you get both. Most times only one.

with an open diff, if both tires break traction equally, then power goes to both wheels. It's when one breaks loose more than the other is when you get the one wheel peel effect.

I don't make a habit of roasting tires. It's pointless and a waste of good rubber. But, the 6 or so times that I have, it's laid down perfect 11's each and every time.

Now in the rain, it's a different story. Both will spin for a second or so, then the left one stops and the right one just goes like a bat out of hell. LOL

I do need to get a solid LSD at some point though. It sucks trying to pull out in traffic on the main drag and the right tire lets loose when you're trying to get up to speed.

That is why it is called the one wheel peeler. LOL

The bad part about an open diff is this. If you are driving it very hard and the car steps out to the right. The diff will transfer all the power to the other wheel in an instant making the car snatch left. It is very dangerous and most folks just flat out loose it when that happens.
