Clutch vs. Viscous: Viscous LSDs are very low maintenance, but due to the inherent lag and low lockup in the viscous coupling, can be difficult to control on higher hp cars - fish-tailing on power; and almost open diff type of behavior where one wheel is spinning much faster. A clutch-type LSD requires more maintenance, but has much stronger lockup and no lag, which gives more consistent and predictable traction. They are also less streetable due to clutch chatter/lockup at low speeds or low traction conditions. Clutch-type LSDs are preferred for performance driving - road racing, drag racing and drifting.
