I have a quick question...why does the Pro4 have adjustable (by replaing the pivot block) front toe blocks, as well as front toe tie rods?
If you screw the droop screws right out (anticlockwise), and then move the suspension up and down you can see the wheel change toe in,out because of the angle of the hingepin, by changing the ngle of the hingepin (inboard toe) you are allowing the "effective" toe in at each point if the suspension travel to be different. If you do not understand what I mean try it. Jonathan
