depends on the exact setup you want/need.
there is not enough space to just put in two more stock clutchpacks.
so you need to have a clutchpack with special, thinner but more durable clutchdiscs. and if you want a belleville spring fitted as well, you need to get some parts machined (or get the machined parts from me as well).

if someone orders such a kit i will ask him what he wants to do with the car and then i send the according parts that he will need to build a setup that fits his needs.
Looks like the kit I'm referring to has thinner clutches and lock plates as they advertise zero machine work is necessary. They also say it was designed for zero preload.

So what is the design of the E46 M3 diff? Is it a 2 plate clutch like the E39 M5?
