Anyone ever tried a Lock Right diff in a D 60?

Thanks. Nothing like trying to run a spool on the street though right? U dont drag and squeel the inside tire when youre turning? Not gonna see alot of in town driving. Mostly non paved roads,mud, snow, cutting wood in the timber and when i go racing its a 50 mile drive down interstate but i litterally only have to make 3 turns. They dont do anything quirky in a straight line do they? Would u recommend them on snow and ice? I know the company does but id rather hear from people that have actually used them instead of the people that sell them
