Last time, is a C-notch really necessary?

[Slammed67]

Ok, I think we decided a while back that on a stock height truck the distance between the top of the wheel arch to the center of the wheel is approx. 22" (on the rear). So to find the amount of suspension drop, simply find the measurement between those two points and subtract that number from 22". Obviously the same can be done for the front end, but I think we decided on about 19" for the front stock height. Tire size has nothing to do with the amount of suspension drop but will affect overall drop of the truck. In my opinion if I were doing a 6" drop in the rear, I'd install a c-notch and get the adjustable panhard bar.
