the original 6061 spyder started coming apart on the mavericks.
they upgraded to the 7075 aluminum spyder to fix that. and the new 7075 spyder is a great deal stronger than the older 6061 spyder. although for extreme racing, or prolonged abusive riding, extremely aggressive riders, the hardened steel spyder is the only way to keep the clutch together. the guys who keep their foot in it for prolonged periods of time running high RPMs of the maverick engine, which we can only guestimate is the harmonics of the engine, is cracking the aluminum spyder and pulling the clutch apart. we have not seen a steel spyder come apart yet.
