is the YS1 tranny LSD???????

 

Only if it's stamped LSD. Some of the JDM ones are (again, they will be stamped accordingly. You can also tell by removing axles, if you can see straight through, you have LSD..... if not, you have inside wheel spin(or maybe it's the other way around). Factory Honda LSD's aren't really that great anyways..... get a Quaife

 

aight thanks
