DriveTrain?

[KaDrifter]

Yeah Yeah some of this is a lsd question but i cann't get a deffinate answer and the ones I do get don't add up so here goes.I have a 96 S-14 base model has SE white face gauges, no ABS, 4 lug,and cruise control.Now as far as i know when i power brake it I leave 2 marks, when I get on it in dirt or when it is wet both tires spin. Had it at my job on the lift when it is in gear tires turn in opp. directions. When o have someone hold the other side with a wrench they won't move. But there is no orange sticker and my engine plate dosn't say it should be lsd, but it acts like it does any help would be grateful.Also i seen a gto direct drive on JSpec.com it is what looks like a pulley that goes in the rack. Would this make the rack faster or a shorter ratio? If not can you make the ration on the rack faster?

Thanks
