First I want to thank everybody for your response even if you haven't done this on a truck just hearing what everybody is saying about the handeling of the C4 I can tell I won't be going wrong with this IFS.
beltfed,
I will probably also be inncorriaprating the air ride supsension so that should help out with the ride height. I email the one of the people at the flat out place about a month or so ago and they said that in place of their coil over shocks that I can go with the Air Ride Technology "Shockwaves" instead. He also said to make sure I set the camber and all when i'm at ride heigh so it will go down the road correctly.
