Bill,
If you find out before I do will you let me know about the = additional depth=20 to be cut.
On the balancing; I have to cover all that with my one rotor ( no = biggie),=20 I can give you all that stuff a little down the track it will only = require=20 lightening the counter balance weights a little.
 
The e-shaft is the same, the rotors lighter =3D lighter balance=20 weights.
There may be some oil volume difference (read weight) , but I = should=20 have that soon, as well the rotor weight. BTW Tracy's apex seals are 33 = grams (=20 per rotor) - got them to-day.
 
Has anyone got a set of new Mazda apex seals handy to weigh - I = guess there=20 wouldn't be much in it anyway - just curious!

I am going to look into this = a bit more=20 and find out how much to mill a rotor.  A lighter rotor =3D> = more rpms=20 without increasing stress?
 
Ed Don't forget lighter rotors would require different balance = weights. I=20 have heard from various sources that the Renesis rotor was lighter and = then=20 that they weigh the same! Both from usually reliable sources, go = figure.
