I had the Recaros in my Focus ST (and didn't get them in my Fiesta ST because my husband didn't like the tight fit). I do just fine throwing the car hard into turns with the base seats without moving around. I don't miss them terribly much, but on my next car, the husband will just have to deal with them since I would definitely get them again. I never had any problems with wrinkling with them in my Focus ST.
