There is 2type of LSD in the world.with sub cat below it.
Speed sensing LSD and power sensing LSD.Under speed sensing LSD are viscous LSD,quafe,Eaton Locker, and etc..cant remember already........and under power LSD is clutch,TORSEN type LSD.
What LSd do???Limited Slip differential. like it says la....to limit the slip..in this case is between 2 tyre ether front or back or front-back like in 4wd.
LSD is a very big subject.but once you learn about it you WILL love it!
after reading this thread..there is some misleading info.so i will try to help fellow friend if im wrong.just laugh at me and correct me ,please.:)
LSD is there to help gain traction.imagine 1tyre on dry and another on ice.What will happen???Open diff/non LSD will give more power to the ice part..why??? coz it sense that the tyre dont have enuff traction,so need more power to get it going...hehehh Its correct what?????u hungry,ur mom give you more food to eat,right??? heheh but in LSD case..LSd will sense the tyre that don have enuff power instead giving it to that tyre...LSD give to the either side of the tyre..to get it going..heheh clever right??
So there shud be no people askign the Q..is LSD good for road?? OF COZ!!.....every car shud have a LSD from the factory itself...but what kind of LSD???hehehhe
I always recommend to get a viscous LSD which is a speed sensing LSD.How to know viscous??jack 2 tyre and spin 1 tyre...........what happen?? both tyre rotate in diff way..hehehe u may ask...aiik i tot LSD both tyre in the same direction???heheh read and learn!........for viscous...the feeling can be feel when you ride the car......the harder you speed,the harder the lock will be......thus why u cant feel it on the straight road......but once the LSD sense there is a different between 2 tyre..the LSD will kick in..hard or not depend on the speed!.
hahah type sooo long......ill stop here will continue later.......
ahh btw im using a Viscous LSD in my Seg.....LOVE IT.......regret i didnt buy it 1st instead buy engine 1st....cheh!!
just for info..in term of handling...
LSD is 100% more better than open diff disregard of the LSD type..
