I have the V-Force front suspension by Speedmerchant. I used it in the first 2 qualifiers in the Orion race at The Track last March. You use the shims I described to set castor on that suspension. You set the camber with the links on the top of the cantilevers. The V-Force has a lot of camber gain with small movements of the suspension. Therefore, the linkage has to be perfect to control bump steer. This is not an easy task. It may be too difficult for the unexperienced driver. Speedmerchant has not officially announced a release date for production units. Mine is a prototype.
