well if you drift alot weld it and if you drift once a month or every 2 months get a vlsd but curbjacker was right it will work when u want it to. oh and if you do weld it get NEW fluid and make sure its full or the diff will get really hot and lock up. its like pulling the ebrake perminently and chances are it will do it on the interstate. ive driven to gainsville from largo twice and orlando a few times and mines ok its your choice
