If it just falls to the floor... one of a few things has happened. Either your pressure plate disintegrated and thus there is nothing to push against... Your fork came loose... You toasted the throw out bearing... or you have serious fluid issues which could be a number of things: air in the lines, bad master or slave cylinder, or all of the above. I'd bleed the setup first... Then see if you can still drive the car. If you can drive it, its not your clutch. And if you are toasting clutches that quick... I have no idea what you're doing... Cuz I've done some hard romps on my OS Gieken, and its never even slipped... I've toasted the tires... but never the clutch. Replacing the clutch is an expensive ordeal. Especially four times over. Start with the smaller things first. Like bleeding. Then have the master and slave cylinders checked. Then, if its none of those. Get another clutch.
