spools are for people who cant afford an lsd diff simple as that.... if spools were so strong and good why doesnt everyone use them?? because they make your car drive like **** everytime you try and do a slow turn in the wet you are asking for trouble... an lsd has a set pressure at which point it single spins called "breakaway" that is so you dont have all the problems that you get with locked or spooled diff's.... there is a reason why they are illegal and not used in production cars because they are ****... sorry i get a bit shitty over stuff like this... also dont forget you eventually may crack your diff housing and/or twist and snap your axles as the the inside axle when turning should not spin at the same speed as the outside so eventually something will give.. i was a mechanic for a very long time working on performance cars and i lost count how many times i replaced locked diffs with cracked housing's and twisted axles not to mention the dent i have in the side of the tub on my ute becuase the bloke who owned it before had a spooled diff and snapped an axle at 80klm which went flying out the side... still want a spool???
