Zero Caster / Camber

[Longboarder]

after thought - this is apparently a problem with the geometry on the 2b wishbones as the camber changes to positive as it moves down

Nope. Should go positive as the suspension droops because you also have roll on corners but the 2B goes negative on droop. On a corner the outside suspension compresses with increased negative and inside suspension extends with increased positive camber. Factor in the roll which takes upper suspension mounts outwards relative to the inners and both tyre treads remain flat to the road. 2B wishbones are fundamentaly wrong because the inner upper mounting point is too high, the wishbones converge toward the hub and the camber goes negative on droop. It would be better if the upper inboard mount could be lowered but failing that raising the outer mount with longer mushrooms sort of does the same thing. Ok, theres loads of other stuff happening but thats essentialy the problem with the wishbone design. Nothing! Its the upper mounting points.

Passed SVA Monday (3a monocoque with adjustable tie bars).

0.5 degree camber

3.0 degree castor

2mm toe in (on wheel rims)

Steering stiff to begin with (all new ball joints and steering rack). Freed up nicely after about 30 miles, tester didn't comment on steering. Stuck like **** to a blanket on way home, gonna get it set proffesionally when registered.

Hope this helps The Spanner Man
