The weights are just bolts, metal locknuts and spacers/washers that you can add on the arms
If you run only one disc you will probably need a lot of pressure--a combo of static and centrifugal that is comfortable to hold pedal down---if you use a lot of centrifugal you need to be aware that as you build rpms at line the clutch will try to engage and you may redlight---takes a balance between clutch, left leg and line lock pressure to keep car from moving( for you former slush box drivers)

Hope you like THE CAM
