Same here, since most of us still use our cars as street cars I want whats best for more "normal" use.

Best diff is plate - instantaneous and consistent regardless of surface or wheel lifting etc... Torsen seems to be next best compromise for tarmac but instantly stops working when one wheel loses traction...viscous seems to be least favoured.

thats all well and good for the front and rear but what about the center? how stiff should it be for a neutral handling car on pavement?

so the 2 way center is more for gravel than tarmac and we should have a 1.5 way center if we go plate

Or is there anyone still interested in a front TORSEN diff instead of a plate type?


Well, I don't think its necessarily dead in the water, it all depends on what ends up being available and what costs are involved, from my point of view in any case.

If the Kaaz option is too expensive, or doesn't happen for some reason, I am definitely interested in this helical option here....even though I would prefer plate, the helical will be a lot better than the front open diff, that much I do know.
But 900 euros + tax + freight both ways, may actually cost more than the Kaaz, but we'll see.....

It depends on what you want your car to do and how you like driving, I feel I would like a 1.5way, even for the gravel...
But its not one of those things where you can try it and then change it to see what the difference is unfortunately...
But I would say you are correct.

Its hypothetical, but I would say you will most likely experience the car pushing more with a 2way, a 1.5 way will allow more slip in over-run so it will probably turn in a little easier...

Actually, if you go to the cusco web site, there is some good literature on how the different types of diffs work and how they would affect the handling of your car...
