I forgot to mention that the camber link settings will only work if you also use 4.5d caster and 2d in-board toe-out. I achieve 4.5d caster by using 6d c-hubs with 1.5d anti-dive. But 4.5d c-hubs and flat arms or 3d c-hubs and 1.5d pro-dive combinations will work as well. The in-board toe-out is accomplished by using 2mm shims in between the forward hinge pin holders of the front arms and the bulkheads (similar to how you adjust rear toe-in, but in reverse).
The overall effects on the front end with .5d static camber are:
* On corner entry: as the wheels are turned partially and the front end compresses with a bias towards the outside wheel, the outer wheel hub will gain just enough negative camber to maintain approximately -2d camber to counteract the positive camber from the tire/rim flexing under side load.
* Mid corner: as the wheels turn to full lock, the inside wheel raises up and the outside wheel maintains its compression, the outer wheel hubs camber doesn't change, but the inside wheels camber changes to approx +1d. Now both front wheels are leaning into the corner with near maximum contact patches.
* Corner exit: as the wheels are close to or at full lock on-power (to keep from swinging wide), the outside wheel raises up slightly and the inside wheel raises up to its downstop, the outer wheel hubs negative camber reduces slightly to -1d, and the inside wheels camber stays the same. This allows the inside wheel to continue to lean into the corner with positive camber and maintain a wide contact patch as it is now pulling the car out of the corner.
* Down the straight: as the wheels are lifting up to their downstops under acceleration, and without any side load, the outer wheels negative camber reduces further to 0d and the inside wheels positive camber reduces to 0d. This ensures wide contact patches on both wheels down the straight allowing it to track true.
* Braking: with both front hubs changing camber to keep their tires flat throughout the different phases of the corner, they will further resist locking up on braking if used.
