> Nicely put John! Cudo's to John for taking the time to put numbers and real geometry to this problem! Now we have some real idea of just how much caster we lose when we chose the different options and just how much change in rubber clamps is required. I chose to shim the lower clamp for ease but I agree with Johns reccomendations of using the upper tube. If this is done before the beam is on the car things will be much easier to deal with anyway.
