Snakebit- I had the BBK adj cable. All the ones that I have heard break or stretch were UPR, Steeda and BBK. I had the same thinking too until I went to nail 3rd gear at the dragstrip only to see the clutch pedal stick to the floor and have no pressure coming up. SVTP has a few threads where people have broken their aftermarket cables atleast 5 times and another guy broke 2 UPR cables in 7 months. I have had friends that had the same thing happen to them. It is very well known that only the stock Cable or the MM universal cable are the two to use.
If you think it was a poorly made cable, then so be it. I offered the info on it and still will advise anyone else to get a stock cable from Ford or the Maximum Motorsports one.
