[Healeys] camber

[Dave Russell]

The term camber as referred to a leaf spring is the amount of curvature 
of the spring leaves.

An unloaded spring placed on a flat surface might have the eye ends 
several inches higher than the spring center/axle attachment. This 
difference is called free camber. Eg- A spring might have 3 3/4" of 
difference, positive camber.

When the same spring is installed & loaded it flattens out to the 
position called loaded camber. This might typically be zero - flat,  
slightly positive - still a bit of curve upward on the ends, or negative 
- center higher than the ends.

The shop manual for a BN1-2, shows a free camber of 3 3/4". When loaded 
to 490 pounds the spring should have about 1/4" of negative camber. A 
total of 4" deflection from no load to full load.
