LSD Differences?
Can someone point out the differences in the S4 clutch type vs the S5 viscous LSDs? I know how they work, but wondering whats the main differences in how they will act. Will you be able to really tell a difference? I have a stock S4 LSD in my GXL, and am about to swap in a 89 GTUs rear diff, for the 4.3 gears. I keep hearing alot of people say that the viscous sucks, and was wondering if that is true, and why?

The problem with the viscous LSD is that it doesn't react fast enough. If you know how they work, then this should make sense. Since the bias torque by the viscous fluid slipping over each other, the LSD won't react until AFTER one of the wheels has already lost traction. When one weel starts slipping, the fluids take a while (relative) to match speed, so there's a delay. That's the main downfall of a viscous unit: Reacts too late.
