i have fitted bmw leather recaros to my car, but had to track down recaro sub frames for ether a golf mk1 or a scirocco, these arent cheep or easy to find but bolt direct to seat base, and then on to car, and gives a factory fit finish, my seats came out of an older bmw 6 serise and include the back bucket seats, i have only fitted the fronts so far,(and these where easy) i have mesuard the back seats up (and they look as if thay will fit no problem) but will require some fabrication of a mounting frame to hold all 3 parts together, and not have them rattleing around in the back. i will update and let yous know if i encounter any problems when i get time to get them in!
