I don't pretend to be a metallurgist or a "glass half empty" bloke
.....but i may be.
What high grade stainless steel ?
there are many types with differing behavioral/molecular characteristics and manufacturing processes that better align themselves to specifically tested applications.
What alloy specifically is being used for the carrier (again see above for important information)
further and important for me also, is to verify whether or not these are full floating buttoned rotors not semi floated. They are advertized as full...but could not verify other than deferring to the actual manufacturers statement for retail.
150pounds per disc plus +shipping to the USA makes them very close to Braking wave rotors or Galfer I would guess if you get a good internet deal.
while i would still want a pair if quality is there....i would rather have a light weight pair of full floating of standard shape than to get on the wave/petal bandwagon.
Just to note -there are many write ups confirming little performance benefit of the wave/petal design to majority mortal bike riders/track day enthusiasts. Weight would be the primary benefit but the other claims of cooling or cleaning etc....would not be of consequence to the majority.
Dang I want a set for the Duc 998 just to write up abount them now
but these are the yum yum
