I just yesterday signed a contract to race the IDM engines but I was running sirio before that. My clutch (via Marc Cruz) for the STI engine was:
2D clutch but use 4 flyweights. No drilled out weights.
Red shoe
Black spring
It is a complete stock 2D clutch but using 4 flyweights. All the rest of the clutch is normal 2D.
Compress the spring down 1.3mm past the end of the crankshaft. Very little gap. Maybe .3mm gap. Endplay almost none. Essentially for endplay make sure that your thrust bearing is free, but with almost no play.
