Hi
I have been looking around for suspension bits for herald and came
across this a couple of days ago. Never used it, never seen them, but it
might be a start.

Chris,
I don't recall seeing anything like you describe in the books I have
from Kas. But it all depends on which suspension you are working with.
On the standard early Spit swing axle, the two control arms in the rear
suspension are the spring (forming the upper element) and the axle
(forming the lower one). Since the position of the suspension has a lot
to do with the camber that is achieved, lowering the car by reducing the
spring arch or by adding blocks between the spring and the diff are the
only two choices you have short of lengthening or shortening either the
axles or spring.
Kas recommends reducing the spring arch to 3.5" which does a good job of
increasing negative camber and lowering the car.
I have also seen some photos of people who have drilled the uprights to
place the spring eyelet lower on the upright and thus changing the
relativity between the upper and lower control elements. I haven't seen
any data on what effect that would have and am not sure that I would
want to go that route. It seems that might have some odd effects on how
the suspension works.
If you get any actual data on that or any other more radical
modifications, I'd love to hear about it.
Cheers,
Joe
