i was talkign with this guy about stalls, becuase his old school muscle car has one and he told me that i should get one too. but that im required to have a lock up clutch stall, becuase i would be spinning all over ther place or be out of control or something like that. just wondering your opinions about this, i have a 98z ls1.

 

Lockup is simply for efficiency at cruise and has nothing to do with tire spin.

 

Use the search, there's way more info there than anyone could ever pack into a few replies here.

PS. you have a convertor with a lockup already.
