Just wondering how different this is from welding the spiders. Does it eat your tires when you turn like a full lock?

compleatly different. the retacked clutches will still slip, giving you the feel of an open dif. once you hit the throttle, and get wheel spin, the clutches engauge, giving you power to both tires. welding the spider gears wont slip at all (just like a spool). you will drag a tire around each turn, possabably break an axle shaft, and loose alot of streetability.

im wondering if adding plates to the pack will make the cltuches grab a little more aggresively.

most likely, possibly too aggressively could even be a near full lockup if there isn't enough space. how much space could you feel between them when installed? maybe a shim of some sort would add some aggressivness while avoiding a possible full lockup.

I'm not sure who is a sponsor here that sells em, but you can Google "Dana 80 clutch" and several options come up.
