You don't have to make a new thread everytime you want to ask a question. There are sections for small questions like this. Please do more research before making threads.

Like stated a spool is no different than a welded diff. Save your money, get your car RUNNING and stop asking about shit you don't need on or in a car with a tired stock KA.

A 2way locks on accel and decel. A 1.5way locks on accel and has partial lock up on decel. A welded diff(or one with a spool) is locked, will shred tires and is not ideal for a DD.

Once again, more research and get your damn car running before you go modifying shit you don't understand.
