use the big kyosho washer (keep it fresh), a .2mm kyosho clutch shim washer and then your clutch bell , then shim accordingly as to only leave .2mm of play max
also to lessen the wear on your shoes pins and flywheel , use 2 undershoe shims .2mm from kyosho with a tiny bit of teflon lube so it creates a moving part under the shoes and also spaces shoes away from the flywheel more
