The basic effect is a more stable tail end under power.
Is the effect mild? Sure is you have to be a good driver and have a well set up car to feel it. The negative diff NEVER locks up the diff like a solid will.
Interesting. . . . My driver (son) runs a negative diff which currently has the clutch removed. The previous owner replaced the out-drives which were flogged out with some "normal' ones which do not have the drive pin hole for the clutch. He couldn't get the kawa ones at the time and didn't believe there was much benefit in the neg. diff, anyway. I intend to get the correct out-drives and put the clutch back in 'cos we want to try it out. Oh, I guess I'll have to remedy that non-existant bearing for the clutch end outdrive, too.
Here's the question:
If your car goes "into a corner off power very nicely", then won't it come out of that corner without much influence from the neg diff, also? I guess, I'm thinking about the last 8 feet going into the corner and then the first 8 feet coming out. I'm imagining that the mild and progressive action of the clutch going into the corner will be duplicated coming out given the similar range of diff rotational speeds - I mean, it won't go into the corner like a 10K diff and then come out, suddenly bighting like a centax, will it?
Maybe all the significant clutch action happens within only 3 feet of going in and coming out of the corner, in which case I could see the point a bit better.
I'd be pleased if you could shed some light on this.
I have also wondered if increasing the weight of the clutch shoes might make a good neg. diff even better. Thoughts?
