[RICK LAKE]

caprimanic The top of the line clutches are all SFI certified. Almost any race clutch has both stickers on them. YOu have to remember that these parts are designed to break first to save the motor and drive train. Ram, McLeod, Quartermaster, Zoom, and others have certified assemblies.
As far as the bell housing, call who ever runs your races and events and see what they say about this. It's their call. They may say it's OK. The only question "I" have is what size flywheel, clutch assembly, weight of complete assembly and MAX rpms are you turning?? The savings of 22 lbs may not be worth your legs. I DON'T want to startup this thread again, this is IMO ONLY.
To me safety is first period, no unneeded risks with this. Rick L. Ps I am also looking to go with a SFI stamped bell from QT this year. It's easier to loss 22 pounds in the car than me.
