12 bolts are good for 450-500HP after that you need a 9" a s60 is pretty much a race rear 1k+ hp.
and a general rule I've come to believe in is 12 bolts are for auto's and a M6 needs a 9" when launching over 5k with a built motor.
There is some one on here I can't recall there user/name but they have broken a 12 bolt 3 or 4 times within a year or so. mike iirc??
That is my 2 cents
