G'day guys and girls, Just wondering if anyone has bought and installed the 1000hp half shafts (cv) that KPM supply on their web page? I'de like to know what others thought of them before forking out the $3700.00 price tag, I've looked into other options for strengthening the weak ass IRS and it seems that this may very well be the most cost effective way of doing so. Also any other ideas and comments would be appreciated.
