Cross reference of an ACT clutch

I need a new clutch for my 2006 mazdaspeed 6 but i dont know how to know for sure if the clutch that i found is the right one that will fit my car. Is there any way to cross reference the part numbers or something to make sure it fits before i buy it???
Here is the link to the one i think fits.

I have this one in my car it's amazing. I know it's more money. but I don't think the one u found comes with a flywheel and u have to use the act clutch with their pressure plate, flywheel, throw out bearing, an pilot bearing. an well ur down their u might as well do it all. Like I said I have this one in my ms6 an it was the best investment for my car. Also get http://www.***************/MACL_107_p/macl-107.htm
Because the stock line will fail with either kit u get. But yes that is the one for ur car.

One more thing. Ur going to need to adjust Ur pedal us this guide. It's really easy just do as it says an ur set.
