Castor corrections

[stevewhite]

For a 3 inch lift will I need 3deg castor correction radius arms or the 6 deg?

Slot your swivels instead. Gives a better result.

IIRC you lose 1 degree for every half inch of lift - so you'd need the 6deg arms.
I've got ~40mm lift on my 110 and the castor was about 1/4deg negative, so needed nearly 4deg correction to get it back to standard 3deg positive (using slotted swivels).

As BigJon already said - its generally accepted that slotting the swivels gives a better result. The reason being it doesn't screw up the diff pinion angles like corrected arms do.
