S5 rotor is lighter and has a machined rotor pocket.

S4 is heavier and has a rough cast rotor pocket.

Search next time.

74-85 rotors are 3mm seals, cast combustion chamber, 12lbs

86-88 rotors are 2mm, cast CC, 10lbsish

89-2003 rotors are 2mm, machined chamber, 9.5lbsish. the 9.7 rotors have a shallower chamber than the 9.0 rotors.

if you search this gets covered like twice a week...
