Whew, Chris, you get archivist of the week award! I used bira system2
(996 cal/s4 rotor) on the eS2, and weighed it when I did the swap. It
was definitely less in weight than the G60 setup, but I can't find the
details, and can't remember where I posted them. I just checked the
bira website but no luck. I do remember the same relationship between
component weights, ie the S4 rotor was much heavier than the G60 rotor,
and the 996 caliper was much lighter than the g60 caliper, for a net
reduction of a couple pounds.
Interestingly, I just put new front rotors on the S2, and one side
rubbed the caliper very slightly such that I had to grind it down. (jack
corner up, start engine in first gear, hold a file against the rotor
edge!) Amazing that manufacturing tolerances could be so sloppy. It
must have been at least 1mm in diam bigger than the one it replaced...
