I only remember seeing one Mk5 Gti with the Recaro seats when I was looking for my Gti, I love them - they are similar to the ones in the VXR Corsa.
I would love a set but don't expect they would be an easy or cheap retro-fit. 
So who has got them?
Oh, and has anyone tried retro-fitting them?
Cheers. 
A dealer near me has a red 5 door manual with them fitted, they are nice and after you get used to high front lip they are quite comfy. But as chrissy states if your a big chap you will struggle.
The way to reduce bolster wear is to always slide the seat back when entering and exiting the car, I 've doen this on my cars with these type of seats and it does reduce wear and tear...until it goes into the dealers and they can't be arsed...
They had sold the car but the buyer didn't like the recaros and asked if they could be swapped, it came back a no due the amount of labour and farting about that it would require to swap them with the standard seats.
