[Fast Freddy 944]

I need cv half shafts, I found some deals on cv's for $75 clams each side, somone told me that they were made in china and they would fall apart after use, when I drive my 951 I sometimes hot rod it, would the auto-zone, or pep-boys 944 style cv's work in a more powerful 951?, I'm on a limited budget nowadays. any help would great!
