Very interesting about the Diffs. If my car does not turn enough. I go from 10,000 to 30,000 and it has more turn-in. The only thing I will change. So someone saying that thicker oil has less turn in, I don't aggree with that. Viceversa. If I dont have enough traction, put the 10,000 back in it and it is alot more hooked up and turns less.

The Neg Diff seems good in theory, you should be able to go into the corner harder and still have traction.

There is the LSD for the 05R.

I really don`t know.. I just bought one for my G4 (V1RR) last time.

Well that is definately not the way that it is "supposed" to work and in my testing it works the way I described (also in many tuning books/guides). However there is always a reverse effect on many tuning options when you go to far however. If you put a stiffer diff in on lower grip conditions it will induce oversteer on and off power which may account for your additional steering.

I`m not the kind of guy who said something that I didn`t try myself.

Pyramid

Yes you are 100% correct about the oil thickness BUT do remember, they are working back to back with your front caster setup. In simple word, if you try to gain steering with more caster (which you should be able to achieve), you will not feel the effect if you were not having thicker oil in the back.

Neither am I. I have been using a Negative Diff for 2 years and I can tell you that the motor power makes no or an unnoticable difference to how hard the diff locks up. It only locks partially and slips anyway.

What car did you test it in?

what is a negative diff ?

Pyramid

On the G4 and I believe it doesn`t matter on what car, the way the clutch engage is by RPM.. so different engine power /pipe /even tire diameter will effect how soon the clutch will automatically engage. What I desire is when to engage just like the two speed clutch so that we can take particular corner exactly at our needs in the right time always at full throttle.

This negative diff did work, that`s why mainly I`m having consistancy problem because the lack of its non adjustable clutch.

AMGRacer

The clutch is always "engaged" even at low speeds since it has no spring. The rotation speed of the diff housing determines how hard it is biting so you are in theory right. Your car would have to be pretty special to have that much more or less speed on corner exit to affect the takeup point of a Negative Diff and for you to feel it. I guess you are much better than me.

We also use the negative diff in a V-One RR/EVO.
I like the idea of the linear friction effect, dependant on revs. My driver thought the effect was rather mild, though. I've since installed some extra weight in the clutch shoes and this accentuates the clutch take up nicely.

You have me wondering about a "solid lock" arrangement like the 2-speed.
This might be good if you could control/tune it sufficiently. I have visions of a medium sweeper where you don't want the gearbox to change and the prospect of the diff locking a split second after might be hairy. . . . anyway.

AMG: It does not overSteer at all. I have never had to much steering out of the car. The rear of the car is alwasys been hooked up. When the traction is low. It just pushes.

This is what you all need.

Now that's just showing off.
