Ive had a limited slip in my car since i was in highschool and i never had any problems with it in wet weather or snow. As with any car on slippery or snow packed pavement your gonna do some sliding, its just how u drive and how u control your vehicle. i mean if you drop the hammer around a corner filled with ice of course your gonna go sideways or worse yet spin out. LSD uses whats commonly called a clutch pack inside and the axles work against the clutches when going around corners and such and also they use a special fluid additive.
