S5 - newer, updated electronics, updated engine. Hard to find a lsd in a n/a, and the viscous ones in the turbo(and n/a if you can find it) suck
s4 - better LSD, more common on n/a models. Doesnt have automatic seatbelts
Ive had 2 s4's and half a dozen S5's, and Ive always liked the s5's better.

so your saying the ones in the turbo suck as well? for s5
Yes, all S5 LSD's were viscous. Viscous LSD's require a a change in wheel speed before they start to lock up. Accelerating out of a corner, the diff feels almost like a rubber band being wound up as it starts to lock up. The clutch type in the S4 feels more predictable and consistent.

Couldn't you just change to a more viscous clutch fluid? It seems like it would solve your problems since it would take less time to "wind up". That said, a clutch could still be more predictable due to the mechanical rather than fluid nature of it. Haven't been able to find it anywhere, but how many clutch plates are there in the S4 LSD?

The LSD unit is permanently sealed. There is no way to change the viscous fluid, or even rebuild the diff if it becomes damaged.

Ouch, that sucks. Is that the case for the S4 pieces as well? Seems silly since clutch LSDs wear out fairly quickly.
