I have some Recaro Pole Position in my car so, so not quite the seats you have but I know what you want to do...
Basically, you mush find some Corbeau rails for the Mk5 platform. If you manage to find these, you only have to unscrew 4 bolts to take the seats of.
But, pay attention what you buy because some seats have a cover over the exterior bolts to make them nicer. These covers prevent you from unscrewing the bolts closest to the door.
In the picture below you can see the cover (just below the rails, hiding everything below):
Then, you must take the airbag into consideration (when the Corbeau seats are in the car). You must deactivate them and then reactivate them when using the normal seats.
Best of luck!
