Kelsey told me to add 6 grams to the heel, 2 grams in the center and none in the tip for the DI kit 5'-8'k. My spider needed to be machined to run a bolt and 2 washers in both sides of the heel.
One thick and one thin on each side just like the instructions say. Only one out of the three actually made contact but all were really close so I machined them cause who knows what happens under load.Were you running two of the thick washers? I think the max you can go with screws on both sides is one thick and one thin washer. If You put two thick washers under the screw it doesn't have enough thread in the hole and causes clearance issues.
