Default 2wd vs 4wd rear diff tightness?

As a general rule of thumb, in a 4wd car, the front diff is tighter than the rear.

Is the tightness of the diff in a 2wd and a 4wd REAR diff tightness similar for a given track?

Would you say that for a given track, the 2wd diff is more similar in tightness to that of:
A. the front diff of a 4wd car or
B. the rear diff of a 4wd car?

Just curious...

Thanks!

You don`t want the diff to slip in a 2wd buggy .

I've always run the diff on my 2wd tightened almost all the way down and it's always worked really well, at least for my driving style. I have a one-way in the front of my 4wd so that doesn't make for the best comparison.

I would say (b) similar to the rear unless you run your rear diff on your 4wd to the point where it slips a little. You just dont want it to slip like stated above.

I have always bult the front and rear exactly the same, and I have never had a diff issue.

Tighten all the way 1/8 turn back.

Just my .02

In 2WD, run the diff as loose as possible, but without any slipping. A tighter diff takes a bit of steering away, looser lets the car rotate easier.
