Hiya
I've never used the simulation kit, I use e wireless cinema kit, very good too
Yes buttkicker amps will power aura pro shakers no probs , just check the wattage on the kit amp you buy to be safe etc
I'd maybe go for the buttkicker kit again ( the simulator one if you don't want to stretch to the cinema one) they are very good
Can't wait for simvibe release !
Yes you need a 2nd sound card, a cheap one is fine but don't go for one that relays on your CPU this will steal fps
