ZF Diff, Price Check Options

[EdwardBlume]

I’m looking to sell off some extra parts.

What’s a ZF limited slip diff worth?
In a rebuilt 901 tranny with 3241 miles?
And a new intermediate plate at the time?

Thanks,

Curious if people have a preference once "factory-ishness" and cost are taken out of the equation.

Drove a car with a torque-biasing diff a few years ago and didn't like it. Might have been a matter of suspension setup, but the car had odd tendencies as you rolled into the throttle on the way out of tight turns. It made me wonder if I might prefer the Quaife or factory LSD.

All LSD's will induce understeer on corner exit. Nature of the beast.

It's a matter of degree depending on the the spec's of the LSD.

If you set up the LSD to not do much bias on wheel slip, you won't get as much understeer tendency. But . . . no free lunch . . . you loose the effectivenss of the LSD when you have lots of wheel slip.

The suspension can be set up (via springs, shocks, and bars) to have more tendency to oversteer to offset the LSD understeer. But of course that brings along a whole new set of problems. Oversteer is not desirable and it also become load dependent on a street car which is not as much of an issue on a race car.

Modern electronic LSD's solve this problem to a large degree by being able to tune how and when the LSD activates.
