I'm a little confused on something so maybe ya'll can help me out. When you add positive caster into the suspension it jacks crossweight into the car when a wheel is steered, correct? And the more positive caster present at the wheel then the more weight that will be transferred to the opposite corner, correct? So, right now I'm running +2 on the LF and +4 on the RF. My question is would it make sense to run more LF positive caster than on the right front? My thinking behind this is that when your making your turn and you countersteer to the right and you have more LF caster it will jack more weight to RR to help that tire develop more bite on the track. Sorry if it doesn't sound real clear because the gears in my head are turning pretty slow right now (just one of them days I guess). Any input on this? Thanks in advance.

Your right on the theory and how everything works. The right front needs more because you need to load the left rear when you counter steer in the turns. The weight in the car "rolling over on the right rear" will load the tire. Now you need to put more left rear in the car to keep from spinning out. Counter steer to control the spin, and in the process the castor is putting more left rear in the car.
