go to new products 2009 guide it explains it there.
Looks like the street twin is for big hp, super chargers ect. up yo 1700 hp and the rst is for up to 900hp

Have had excellent luck with center force. Have one behind each of my 2 340's. Hold up great. Friend had one behind a nasty 440. He was very happy also.

I have had great luck with the centerforce behind a strong street 440. Flawless performance, however I have heard they can be sensitive to bellhousing centerline run-out. I dialed mine in and it was the best clutch I ever had.
