He guys,
I just had the Walker Evans rebuilt and revalved. I'm still dialing it in and can't seem to get it to hold in the corners. The sled feels very tippy now! Any suggestions would help. I did notice while putting the skid in that the rear scissor stop was in the lower hole. Should I move it back to the upper hole.

Make sure the spring tension is way loose on your front skid shock. If it is tight, it acts like a fulcrum.

as said but the prox itself is not a fast flat cornering sled, the edge is. the prox will never handle like an edge will just because if its design. as said less center preload, more torsion preload, move rear block forward
